| 摘 要： | 根据动能定律和刚体平面运动微分方程,建立了圆锥杆倾斜侵彻半无限厚水泥靶时的动力学方程。对这些方程进行数值求解,求得侵彻时的轴向撞击力和横向撞击力,讨论了初始侵彻角度对轴向撞击力和横向撞击力的影响。在此基础上,建立了圆锥杆的波动方程,分别研究了正应力和剪应力在圆锥杆中的传播规律和分布规律。研究表明,初始侵彻角度对轴向撞击...

| Abstract: | Dynamic equation on the penetration of a conical rod against half-infinite cement target was established by using the theorem of momentum and the law of kinetic energy.The axial impact force and the lateral impact force were determined by the numerical solution of the nonlinear equations,the influence of the initial penetration angle to the axial impact force and the lateral impact force were discussed.On this basis,the wave equations of the conical rod are established,and the propagation and distribution o... |
