To reveal the failure mechanism of Al50Si silicon aluminum alloy under impact loading, MCM modules, and a crystal-integrated receiver/inverter were used as the research object, the pendulum-type shock response spectrum test bench was used to conduct a large number of impact loads test of 1600 g, and the fractured samples were examined by scanning electron microscopy (SEM). The results show that the Al50Si silicon aluminum alloy exhibits direct brittle fracture characteristics under a large impact loads; in order to realize the vibration impact protection of Al50Si silicon aluminum alloy, numerical simulation of the structure with impact loads was carried out using response spectrum analysis and wavelet synthesis time domain method, and the simulation method is highly accurate, with a maximum error of 2.3% compared to the experimental results. The product design has been optimized according to numerical simulation results and verified by 1600 and 2000 g impact tests, which can effectively improve the reliability of the product against large impact levels.
