Embodiment Construction
[0034] Below in conjunction with accompanying drawing, the present invention will be further described;
[0035] like figure 1 and figure 2 As shown, the test method for the dynamic performance of seat belts includes the following steps:
[0036] Step 1: Obtain the waveform of the seat belt dynamic performance test
[0037] Weigh the rigid seat 3, simulated B-pillar 4, Buckle mounting plate 8, foot pedal 9, wedge-shaped mounting plate 5, rectangular mounting plate 6, etc., and input the mass of each tooling and dummy into the trolley system 1 In the control software, iterate the seat belt dynamic performance test waveform according to the known waveform (that is, the target waveform) until the two waveforms basically coincide and the speed change of the test waveform is within the range of 55±1Kmph.
[0038] Among them, the target waveform is the standard waveform of the seat belt dynamic test produced by using the acceleration waveforms simulated by the actual frontal col...
