Description

technical field [0001] The invention relates to a performance test system of auto parts, in particular to a cold shock resistance test system of non-metal parts of the car. Background technique [0002] Automobile non-metallic parts refer to all plastic, fabric, rubber, glass and other parts of the car. The previous cold resistance test can only measure the low temperature resistance performance of non-metallic parts of automobiles, but cannot solve the performance when subjected to external forces at low temperature. Even though non-metallic parts have better low-temperature performance under non-impact conditions, the lack of performance test experiments when subjected to external forces at low temperatures will not truly reflect the cold-resistant performance of non-metallic parts, resulting in automobiles running at low temperatures Hazardous situations can occur during the process.
