Experiment Design of Wave Generator Parameters of Gun Simulation Test Device

通过高速大质量块冲击炮口来推动火炮后坐是一种技术可行的火炮后坐模拟试验方法。为保证该模拟试验方法精度,基于ABAQUS软件建立了火炮模拟试验装置及力学模型;基于橡胶试样的拉伸、压缩试验得到橡胶材料的应力应变关系,建立了波形发生器的超弹性模型;选取波形发生器左右两个橡胶块的直径、硬度及厚度等结构参数为试验因素,根据火炮动态特性的平均及最大误差建立了目标函数,通过均匀设计试验获取了一组最优的结构参数,为火炮模拟试验装置的工程设计提供了依据。

It is a technical feasible gun backseat simulation experiment method by high-speed big mass impacting gun muzzle to push gun recoil.In order to ensure the accuracy of simulation experiment method,gun simulation test device and mechanical model are built based on ABAQUS software.superelasticity model of wave generator is established based on relationship between rubber＇s stress and strain obtaining by experiment of rubber＇s tension and compression.Selecting structure parameters such as diameter,hardness and thickness etc of wave generator＇s two rubber block as experiment factor,objection function is built according to average and maximum error of gun dynamic characteristic.The most optimal structure parameters are obtained by even-design experiment,which provide basis for engineering design of gun simulation test device.
