摘要
Abstract
Aimed at the testing machine for crash test to test the dynamic performance of passenger car materials,the applicability of JB-W450GL high strain rate impact tensile machine in the evaluation of crash deformation and energy absorption characteristics of passenger car materials was introduced.From the aspects of impact tensile testing machine principle,load input mode,tensile stress wave generation principle,specimen size and engineering stress and strain measurement method,the specific implementation plan was put forward.At the same time,the core functions,main parameters and advancement of the testing machine were introduced.关键词
