Slam testing of a door module is one of the most significant fatigue-related testing process to meet the qualified performance guideline that is stipulated by major car makers. And every testing procedure of the slam testing is done as slamming the moving part of a door module by hydraulic actuators in practice. Current testing situation is required considerable efforts on the way to prepare the slam testing and even more, even a single specimen result sacrifices at least two weeks or more physically. In this paper, a accelerated similarity testing methodology of a door module is proposed using vibration test equipment instead of the honest testing procedure, that is purely slamming the target system repeatedly up to a failure mode. The response of a door plate module during slam testing indicates that fundamental resonance behaviors of the specimen accumulates the fatigue damage on hot spot of the door plate module. So, the accelerated similarity alternatives of the slam testing is proposed by the block cyclic excitation of which spectrum is consisted of resonance frequencies of a target system. Also, the calibration of block cycle testing is conducted through the comprehend the fact of failure mode obtained by the multi-axial vibration testing. |
