Abstract

Изобретение относитс  к области измерительной техники, а именно к способам измерени  деформаций с помощью различных датчиков. Цель изобретени  - измерение фактической деформаций детали, имеющей остаточную технологическую деформацию, - достигаетс  за счет того, что в данном способе предварительна  деформаци  чувствительного элемента, закрепленного на детали и изготовленного-из того же материала, что и деталь, равна остаточной технологической деформации детали.The invention relates to the field of measurement technology, and specifically to methods for measuring deformations using various sensors. The purpose of the invention is to measure the actual deformations of a part that has residual process deformation, is achieved due to the fact that in this method the preliminary deformation of the sensitive element attached to the part and made of the same material as the part is equal to the residual technological deformation of the part.

Изобретение относитс  к измери- т льной технике, а именно к способам и|змерений деформаций твердых тел с помощью различных датчиков.The invention relates to measuring techniques, in particular, methods and measurements of deformations of solids using various sensors.

Цель изобретени  - измерение фактической деформации детали, имеющей ойтаточную технологическую деформацию ,The purpose of the invention is the measurement of the actual deformation of the part with the test technological deformation,

При этом закреплен- на детали чу вствительный элемент п|о существу  вл етс  частью ее по- в1ерхностного сло , деформацию которо- гк и регистрирует.датчик: вначале ее 1 сходное значение, а затем - измене- деформации в процессе испытани  р етали.: The goal is achieved by the fact that in the datfm measuring method the sensitive E | Lement in the initial state has a distortion registered by the sensor that is numerically equal and equal in residual technological deformation of the part. At the same time, the sensitive element of the subassembly is fixed to the detail; it is a part of its surface layer, the deformation of which is registered by the sensor: first its value is 1, and then the deformation change during the testing process.
