摘要

火炮动力后坐试验装置通过高速冲击头撞击炮口推动火炮后坐，为新型后坐模拟试验方法。为分析该试验方法模拟后坐的准确度，通过实弹射击试验及基于试验装置的模拟射击试验，获取两种射击条件下后坐位移及速度时间序列；用时间序列相对误差的加权均值表征数值相似度，据时间序列曲率误差值求取形状相似度，并基于多属性指标评价理论计算综合相似度，进而对试验装置的后坐模拟准确度进行评估。该研究可为试验装置用于靶场试验提供理论依据。

Abstract

Gun-power-recoil test machine is a new-fashioned recoil simulation test machine, with high-speed mass impacting the muzzle to promote gun recoil. In order to analyze recoil simulation accuracy of the test method , through practice firing test and simulation firing test based on the test machine, recoil displacement, recoil velocity time series of two firing conditions were obtained. Numerical value similarity was represented by weighted average relative error of time series. Shape similarity was calculated by curvature relative error of time series. Comprehensive similarity was obtained based on multi-index evaluation theory, and recoil simulation accuracy of the test machine was analyzed. This research will provide a theoretical reference for the range application of gun-power-recoil test machine.
