Definitions

  • the invention relates to a method for the design and construction of complex technical products and their components, in particular internal combustion engines, tools for computer-aided engineering work and tools for computer-aided design being used for the simulation calculation, and program logic for carrying out the method.
  • the object of the present invention is to change the development and construction process for a complex technical product in such a way that all the requirements mentioned can be met reliably and in compliance with high quality standards in a given time frame.
  • sub-requirements In the case of highly complex products in particular, it is advantageous if, after the product requirements have been defined, they are divided into sub-requirements, the sub-requirements preferably being functionally coordinated with one another. Subsequently, it is provided that sub-models to meet the sub-requirements are selected from a predetermined group of aids for computer-aided engineering work. The submodels can be assigned to individual subrequirements. By merging the partial models into a digital model structure, a development model for the entire model can be generated.
  • the invention provides that the product is subdivided into main assemblies within the product structure and that each main assembly is assigned a main skeleton part with auxiliary geometric elements. In this way it is possible to define the structure of a construction by means of relationships between basic geometric elements at a lower level and between components at a higher level, and to automate a construction process even when the parameters of these relationships change. This approach allows you to build a rough design that can be refined step by step without breaking relationships.
  • Fig. 5 shows a communication scheme at the interface CAD / CAE
  • Fig. 6 shows a construction method for an overall engine.
  • the method according to the invention is described using an internal combustion engine.
  • the process is of course also suitable for other complex technical products.
  • Metamethodology is a general approach, the scope of which should be independent of the CAD / CAE tools used.
  • the metamethodology comprises 5 sub-aspects that also interact:
  • the development of sensible sub-models for complex main engine components and their combination into a digital product model enables the component properties to be clearly controlled in accordance with the technical requirements (e.g. function, package, manufacture, assembly, customer service, testability, etc.).
  • the control is carried out by control parameters that are derived from the component specifications or specifications.
  • the goal is the parameterized control of the entire basic engine, consisting of the main assemblies cylinder crankcase, crank drive, cylinder head, valve train and timing drive.
  • control parameters of the individual main assemblies are hierarchically subordinate to the strategic considerations, such as staggered displacement, determination of the number of cylinders, designs, etc. This clear reference flow enables "top-down" control and prevents sources of error through circuit references.
  • the number of control parameters is deliberately limited so that the main motor functions can be displayed on the one hand, and rapid and reliable changes on the other hand Parameters summarized in sets.
  • the basis for a continuous process chain is the mapping of the individual production steps of a component, depending on the complexity different model strategies of the component as well as the manufacturing and machining process are used.
  • the design methodology CON is influenced both by the control parameters SP and by bilateral output variables BO.
  • the tools of the computer-aided engineering work CAE consist for example of accompanying calculation CAC, thermodynamic calculation TDA, finite element method FEA, flow dynamic calculation CFD and acoustic calculation ⁇ CA.
  • simulation tools from the field of CFD (Computational Fluid Dynamics) and FEA (Finite Element Analysis) can directly benefit from the advantages of 3D geometries for the creation of their input data, the difficulty with other tools increases even further, since the for Some CAE calculation tools sometimes require geometry-based data to deviate significantly from the geometric information inherent in an element of the product structure.
  • a characteristic of some simulation tools used in the concept phase of the development process is that they have a very high degree of abstraction. This is partly the case because less information is often available for the definition of basic design features, so it does not have to be calculated very precisely, but short throughput times are of great importance for fast optimization.
  • a known CAE tool for example, is used for the dynamic calculation of valve and control drives of internal combustion engines. It is used in the earliest concept studies and is used with increasing engine maturity with increased detailing in terms of modeling and data. A calculation of the single valve started and, with satisfactory results, proceeded to the full valve train calculation. This is followed by a further increase in complexity with the addition of the control drive or the drive of injection elements.
  • one of the parameters that influences the dynamics of a valve train from the start is the rocker arm stiffness.
  • the aim in the example above is to automatically map the CAD model structure or its data to the CAE data model.
  • the solution shows that in addition to the need to assign components and transfer their parameters appropriately, methods must also be selected and parameterized that are used to determine the required data.
  • FIG. 3 also shows a number of additional orientation points PNTO, PNT1, PNT4, PNT5, PNT6, PNT12, PNT13, PNT14, PNT15, PNT22, PNT24, PNT25, PNT29 , APNTO, APNT1, APNT2, which were assigned to the valve train as part of a methodology. This means that they are retained even if the design is changed. This fact can be used here to easily determine the rocker arm stiffness over the cam angle.
  • the orientation of these orientation points in addition to the component geometry, for example in the form of a data file in STL format (stereolithography format), the representation as shown in FIG. 4 succeeds when the correct coordinate system is taken into account.
  • STL format stereolithography format
  • a CAD data exchange layer e.g. as part of a CAD management system, provides the information in the CAD / CAE interface and manages access and communication. Since the development process is iterative, the calculator or his tool needs direct access to the design to quickly optimize the component shape. He can carry out parameter studies in a simple manner and without involving the designer. However, this is always done in a system that allows the configuration to be adopted when released by the designer.
  • the set-up methodology takes into account the requirements of the metamethodology, but refines the level of detail in terms of practical implementation so that the scope depends on the CAD tools used.
  • the construction methodology makes it possible to define the construction of a construction by means of relationships between basic geometric elements at a lower level and between components at a higher level, and to automate a construction process even when the parameters of these relationships change. This approach allows you to build a rough design that can be refined step by step without breaking relationships.
  • the construction methodology should meet the following objectives:
  • the basic structure of the overall engine is carried out via several main assemblies (crank mechanism, crankcase, cylinder head, valve train, timing mechanism), each of which contains its own main skeleton part.
  • This main skeleton part contains all auxiliary geometries (axes, planes, etc.) that are necessary for the components of the respective main assembly and serves as the top reference for these components.
  • the motor skeleton assembly MSBG is the key element of the applied design methodology. All main skeletal parts HSGM, HSMA, HSKG, HSKT, HSZK, HSVT, HSST are integrated in it. Within the motor skeleton assembly MSBG, the construction parameters PSl to PS7 are exchanged between the individual main skeleton parts via assembly relationships. Since only parametric values are exchanged at this assembly level and no copying geometries are allowed between the individual main skeleton parts, each of these main skeleton parts can also exist on its own. In order to avoid redundancies, a comparison of the parameter values PSl to PS7 is enforced in the motor skeleton module MSBG so that all main skeleton parts functionally and logically match each other.
  • Main skeleton parts are available for the following main engine assemblies:
  • Each main skeleton part is completely independent and contains all the reference geometries relevant to it in the form of curves, planes, axes, points, coordinate systems, etc.
  • the corresponding design parameters are then derived from the respective reference geometry elements and transferred to the other main skeleton parts.
  • the reference geometry elements are then passed on directly to the sub-skeletons or components via copy geometries in order to ensure a clear "top-down" reference flow.
  • the main skeleton part and the relevant component skeleton are basically integrated into each assembly.
  • the copy geometries created in the assemblies refer from the main skeleton part to the component skeleton. All other parts in the assemblies only refer to the component skeleton and must be independent of the main skeleton part.
  • the assembly itself consists of all relevant parts such as cast cores, unfinished parts and finished parts as well as attachments that belong to the assembly. This makes it possible to design several people on one assembly at the same time ("multi-modeling"); the maintenance of the correspondence of the interface references is nevertheless guaranteed.
  • features are an extended class of elements that carry more than just geometric information: they are construction elements that, in addition to their geometric description (shape features) also contain information about their behavior in construction (semantics).
  • shape features are construction elements that, in addition to their geometric description (shape features) also contain information about their behavior in construction (semantics).
