[0002] With the rapid development of industry, people pay more and more attention to the quality and durability of products. During the use and transportation of products, they will be affected by dynamic environments such as vibration and shock. Such effects often lead to failures such as wear of product connection cables, loosening of product fixing bolts, intermittent contact of product contactors, short circuits in the circuits of electrical products, failure of components, fatigue fracture of structures, and wear of bearings. These failures greatly reduce the reliability of products and cause serious consequences.

[0003] In order to ensure the quality and prevent performance failures and structural damages from occurring or occurring less during the use of products. Almost from the production of product components, the durability of products is detected by vibration tests according to standards.
