Abstract

The catapulting device is widely used in the aerospace field. In the process of simulated impact test of a certain type of missile, a design method of the pulley group ejection device is proposed for the test system with large load mass, large impact speed and short acceleration time, which elaborates The design idea of the catapult device with pulley group. Based on UG, the structural design of each part of the ejection device was carried out, and the composition of each part was elaborated. Based on AMESim, the mathematical model of the pulley block is established, and the offset load force generated by the pulley block model is obtained. Based on Nastran, the finite element analysis of each part of the ejection device is carried out, and the structural deformation of each part of the ejection device is obtained. At the same time, it provides a good idea for the design of high-speed catapults.
