Description

Emulation dummy for ejection test

Technical Field

The invention relates to the field of ejection life-saving tests, in particular to a simulation dummy for an ejection test.

Background

As early as the 40 s of the 20 th century, the catapult seat test of germany and uk was initially carried out by volunteers. When the aerial catapulting test is carried out, the head, neck, limbs and lumbar vertebrae of a volunteer are subjected to huge impact during catapulting, and the test has great harm to human bodies. With the continuous rise of the aircraft speed, the aircraft gesture becomes more complex, and the aerial and ground ejection tests in the process of developing ejection seats are more dangerous, so that volunteers cannot conduct the tests. Therefore, the simulation dummy becomes an essential experimental tool for carrying out a large number of high-speed catapulting and high-speed air flow blowing tests in the air and the ground, and plays an important role in the development of protective life-saving equipment and physiological identification thereof.

The simulation dummy is a test tool for simulating human body in dangerous places, and has the external dimensions and structural functions similar to those of a real person, can reflect the human body replacement of an external environment, can bear certain material wave energy, and is a test tool for simulating human body in dangerous places. The pilot's protection life-saving product needs to go through the evaluation, the examination of many times ground test from first appearance stage to batch delivery stage, and test dummy is the key in this test system, through carrying on sensor, data acquisition system etc. and obtain the physiological response parameter of human body when protection life-saving equipment work, replace pilot's in the high-risk ejection environment inspection product function with design index consistency to provide the basis for protection life-saving equipment's optimal design. The dummy for the ground ejection life-saving test must have the appearance size, mass distribution and limb movement characteristics close to those of a real person, and has the test verification capability of individualized customization model size diversification of pilot protective equipment.

In GJB 4856-2003 "Chinese Male Pilot human body size" and GJB 6895-2009 "Male Pilot human body inertial parameter", the 3 rd percentile fighter pilot human body size and the 98 th percentile fighter pilot human body size and the regression equation quality prescribe the sizes and weights of the P3 simulation dummy and the P98 simulation dummy, specifically as shown in FIG. 1 and corresponding Table 1; FIG. 2 and corresponding Table 2; fig. 3 and corresponding table 3.
