空间发射装置管口缓冲特性与参数影响
Buffering characteristics and parameter influence of launch canister of space launch devices
摘要
Abstract
To address the issues of strong impact force and significant vibration at the launch canister of a space launch device,this study proposes a launch canister energy-absorbing structure.The aim is to reduce the impact force generated by the projectile at the launch canister and mitigate launch canister vibration,thereby further enhancing launch accuracy.An internal ballistic model served as the loading condition to establish a launch dynamics model un-der varying loads.Both simulations and experiments demonstrate that the deformed state of the energy-absorbing ring consistently exhibited a petal-shaped inward deformation.The deformation height error was 14.23%,the recoil force peak error was 0.30%,the forward impact force peak error was 10.72%,the velocity error was 4.14%,and the ac-celeration peak error was 4.88%,verifying the model's accuracy.Based on this validated model,the influence of key structural parameters on the forward impact force and pitch displacement was analyzed.Results indicate that an energy-absorbing ring inclination angle of 35° yields optimal energy absorption.At this angle,the peak forward impact force is reduced by 9.22%compared to the pre-optimized state,and the minimum launch tube pitch displacement am-plitude is 3.45 mm,representing a 1.71%reduction.When the collision contact surface radius between the energy-absorbing piston and the energy-absorbing ring is 7.5 mm,the peak forward impact force decreases by 6.83%com-pared to a radius of 5.5 mm,with the change in radius having a relatively minor effect overall.This research provides theoretical support and practical engineering reference for the design of high-efficiency space debris removal payloads.关键词
