Shaft dropping test device and design method thereof

The invention discloses a shaft falling test device and a design method thereof, relates to the technical field of rail transit, and aims to solve the technical problem that a traditional shaft falling test is inaccurate in vibration reduction effect evaluation. The drop shaft test device comprises a foundation soil simulation layer, a vibration reduction rail component and at least one pre-pressing loading component. Wherein the vibration reduction rail component is arranged on the foundation soil simulation layer; the vibration reduction rail component comprises at least one unsprung mass simulation assembly. The pre-pressing loading component comprises a loading assembly and a vibration isolation bearing assembly. The vibration isolation bearing assembly is arranged on the unsprung mass simulation assembly, and the loading assembly is suspended at the top of the vibration isolation bearing assembly in a lifting mode. Therefore, the method has the advantages of accurate and scientific test results. 本申请公开了一种
