Abstract: With the continuous updating and development of the standard system and testing methods for car crash safety testing in various countries, the application scope of flexible coordinate measuring machine in automotive crash testing is increasing, and it has become one of the main testing equipment for automotive crash testing. This article briefly summarizes the application cases and methods of flexible coordinate measuring machine in automotive crash test processes , including compartment intrusion measurement, seat adjustment, H-point position measurement, dummy installment and measurement, photographic targets positioning, vehicle collision reference line positioning, and moving progressive deformable barrier (MPDB) honeycomb aluminum barrier deformation measurement. It provides a reference for engineering and technical personnel who are about to engage in automotive crash testing to understand the application of flexible coordinate measuring machine in automotive crash testing

Key words: Flexible coordinate measuring machine; Compartment intrusion measurement; Dummy installment and measurement; Photographic targets positioning
