摘要
通过单独计算构件受撞击部位的接触局部变形,建立了弹性运动构件相碰撞的系统动力有限元方程,并采用近似的数值求解方法,使得有限元矩阵方程的计算线性化,从而有效地减少其运算量,通过实例计算,证实了本文方法的计算结果合理、准确。
A dynamic finite element equation for the collision among moving elastic objects is established, calculating independently the local contact deformation on the collided position of the objects. With an approximation method, the finite element equation is linearized, and the computation much simplified. The rationality and accuracy of the computational results of the proposed method are confirmed through concrete examples.
