摘要
单兵无后坐炮发射时运动十分剧烈、复杂,传统不平衡冲量测试装置不能准确测量各方向力系,从而对测量结果的准确性造成影响,因此,基于十字梁型结构研究了一种可实时监测各方向力系的六维力传感器。利用有限元软件建立初始模型并进行单因素分析,基于响应面法以关键尺寸参数完成响应面试验设计,结合最小二乘法得到响应面模型,采用多目标粒子群算法优化策略进行优化求解,研制原理样机并设计标定系统进行标定。仿真与实验结果表明,优化后力矩通道测量灵敏度最大提升32.24%,力通道测量灵敏度最大提升31.02%,解耦后的维间耦合最大1.01%,标定结果符合测量要求。
With the drastic and intricate motion of the man-portable recoilless gun during firing,it is difficult to accurately determine the force systems in each direction using a traditional device for unba-lanced impulse testing.Therefore,a six-axis force sensor that can monitor the force systems in real-time based on the cross-beam structure is studied.The preliminary model was established using finite element software and subjected to single variate analysis.In addition,the response surface test design was completed based on the response surface methodology using key dimensional parameters,where the response surface model was obtained by the least squares method.The multi-objective particle swarm optimization was also implemented to optimize the solution.An experimental prototype was developed,and a corresponding calibration system designed to calibrate the prototype.In conclusion,the simulation and experimental results show that the maximum improvement of the measurement sensitivity of the torque channel is 32.24%,and that of the force channel is 31.02%after the optimization,and the coupling between dimensions is 1.01%after decoupling.The calibration results meet the measurement requirements.
