| 摘 要： | 本文以85加农炮为实例,根据实测结果,估计了土壤的物理参数,从而确定了火炮的边界条件;用塑性杆元及线性阻尼器模拟了驻退机、复进机的作用;在此基础上,建立了火炮整体的有限元模型。所得计算结果与实测结果符合较好。

| Abstract: | In this paper, with cannon 85 as an example, according to the actually measured result, the physi- cal parameter of the soil is estimated and therefore the boundary condition of the gun is determined. And also, the function of the recoil mechanism and the counterrecoil mechanism have been simulated by using plastic rod element and linear damper. On this basis, the finite model of the whole gun has been established. The obtained calculated result is in good accordance with the actually mesured result. |
