Research On The Principle Of Recoil Energy Reduction For Rocket Launchers

A new type of field launched rocket launcher with linear propulsion is developed,which produces huge recoil energy from the new launch technology.In order to solve this problem,this paper designs an energy absorbing device that can bear and consume large recoil energy.In this paper,the process of the emitter recoil is analyzed in detail.The principle of energy absorption is to use the mode of hydraulic buffer to control the flow of the system by the throttle valve to achieve the purpose of buffer.This paper makes a detailed analysis and Research on the recoil process of the energy absorption device.The boundary is confirmed by the finite element analysis software Abaqus,and the motion trajectory in the recoil process is designed.Because of many uncertain factors and complicated working conditions,we will do detailed research on the different ways of buffer stroke,different temperature,different hydraulic oil and different load conditions through Amesim and Adams joint simulation of liquid and solid.According to different conditions,the program is programmed by MATLAB,and the opening area of throttle valve under different working conditions is obtained,and the area of opening area under single variable is compared.Through the comparison of the different conditions of recoil process,found that the influence of different hydraulic oil under different temperature of recoil process is different,choose the kinematic viscosity slightly affected by the temperature of hydraulic oil is more appropriate;through different buffer stroke compared with different load analysis,the meet emission conditions as far as possible so that the buffer stroke increases,and the load is small,the stability is better;the fixed mandrel structure strength should have higher requirements.The method of regulating the opening area of throttle valve and controlling the recoil process can provide reference for other product design with cushioning structure.
