摘要
根据动量定理和动能定律,建立了圆锥杆垂直侵彻半无限厚水泥靶时的动力学模型,并对所得到的这些非线性动力学方程进行数值求解,藉此分析了等效撞击力,进而根据牛顿第二定理建立了圆锥杆的波动方程,研究了应力波在圆锥杆中的传播特性和规律.
Dynamic equations for the penetration of a conical rod against semi infinite cement target are established by using the theorem of momentum and the law of kinetic energy.The impact force is determined by numerical solution of the nonlinear equations. Then according to Newton's second Law, the wave equation of the conical rod is established and the stress wave propagation in it is studied.
