Design and Finite Element Analysis of Drop Test System for Fully Loaded Packages.

To comply with the reliability test standards for military supply packages, a drop test system for fully loaded packages is designed. By analyzing the free fall state, a structural scheme of overall screw lifting, 4V guide-wheel and guide-rail guiding, pneumatic overturning and pneumatic locking is proposed, CREO modelling and CAE simulation mechanics analysis are used to design, optimize and verify the structure, and pre-drop pressurization and delayed release are adopted to meet the requirements of strength and safety factors of special test devices. The new drop test system meets the test requirements of a load of 150 kg, a drop height of 4 m and an intelligently adjustable lifting speed, which solves the problem of the lack of package drop test system in China and can provide a reference for the design of similar products.
