| Abstract: | A new multi-condition drop test bench is designed and its structural mechanical property is also checked.The test bench consists of five parts i.e.,platform system,lifting system,dropping system,load acquisition system and security system.And Solidworks is used in 3D drawing of their components.Based on the simulation results of a virtual prototype of a lunar lander,a transient dynamic analysis on the device is presented by using the finite element method and its impact resistance performance is checked.The result shows that the test bench meets the requirement of lander’s drop test. |
