火炮动力后坐试验台波形发生器优化设计研究

摘要

针对火炮动力后坐试验台波形发生器设计问题，基于ABAQUS建立火炮动力后坐试验台有限元模型；通过橡胶试验，选Arruda-Boyce模型作为波形发生器材料本构模型；以火炮模拟试验与实弹射击时后坐动态特性的平均相对误差为试验指标值，基于正交设计法建立初始样本数据，采用QPSO-LS-SVM算法对波形发生器进行优化设计。该研究将为我军火炮动力后坐试验台的设计研制提供理论参考。%For the design of waveform generator of a gun-power-recoil test machine,a finite element model of the test machine was built based on ABAQUS.According to the results of rubber tests,the Arruda-Boyce model was selected as a material constitution model for the waveform generator.Taking the average relative error of recoil dynamic properties between the results of simulation test and live firing as a design objective,the initial sample data were acquired based on orthogonal design method,and the QPSO-LS-SVM algorithm was applied to optimize the design of waveform generator. The conclusion will provide a theoretical reference to the design of gun-power-recoil test machine.
