[0002] The reciprocating motion of an object or a particle relative to the equilibrium position is called vibration. It is a test conducted on the actual object or model of the vibration system in the field or laboratory. The vibration system is a mass elastic system excited by the vibration source, such as a machine, structure or its parts, organisms, etc. It has been extended to various industrial sectors such as power machinery, transportation, construction, and environmental protection, labor protection, and its application is becoming more and more extensive.
[0003] With the development of modern industrial technology, the emergence of various large and small industrial equipment has greatly improved the production efficiency of industrial production. Various parts are needed to be assembled before use, and various parts need to undergo a series of test experiments before use, such as vibration tests. However, the electric vibration table usually vibrates the components to be tested linearly from different directions, and the vibration direction is relatively single, making it difficult to fully simulate the vibration environment of the components to be tested, which may lead to inaccurate tests. Therefore, we propose a vibration simulation test bench to solve this problem. Utility Model Content
