The roof crush resistance test of passenger cars is one of the important tests in the national mandatory automobile inspection and automobile evaluation specifications.With the iteration of the standards,more and more relevant standards begin to focus on the crush injury of the passenger head during the test.Through the research on the relevant standards at home and abroad,a passenger head injury measuring device with the electric actuator as the main control unit is developed.The head positioning of the device is fast,and the operation is simple,it supports six degrees of freedom adjustment,and can be fixed with the seat mounting holes of different body in white.It can automatically and quickly collapse when exceeding the specified load;there are two trigger modes,external trigger and manual trigger.Through external trigger,the data of the device sensor and the roof jacking device can be collected synchronously.The collection frequency is high,and the function of data revisit and export is available.
