Abstract

In this paper, a dynamics model of a launcher on a combat vehicle using hydraulic jacks is established. Theoretical foundations of multi-object mechanics are used to set up mathematical equations describing the vibration of a launcher when firing. The ground in the surveyed model is considered as an elastic element with K hardness and viscous drag coefficient C. The research results are applied to calculate the BM14 combat vehicle, the stability of the BM14 launcher when single and multiple fired is specifically surveyed in the following cases: Using hydraulic jacks, the ground is considered to be inelastic; Using hydraulic jacks, BM-14 combat vehicle is placed on the elastic ground; Without using hydraulic jacks, BM-14 combat vehicles are placed on the elastic ground. Survey results show the reliability of the launcher when firing. The content of the paper is a theoretical basis to contribute to the process of improvement, design, manufacturing, and exploitation of combat vehicles that use hydraulic jacks with high efficiency.
