利用计算机进行数值计算来研究科学技术中的复杂问题,已经成为现代科学技术研究的一种重要方法.本文用两个例子来介绍比较复杂的力学问题的数值计算研究方法.1双振子弹簧系统运动的数值分析文献[1]研究了图1所示的双振子弹簧系统中物体的运动问题.在图1中,物块A、B的质量相等,在物块A上施加一水平恒力F作用,物块B足够长,放置在水平地面上,所有接触面都是光滑的,轻弹簧开始处于原长,运动过程中始终处于弹性限度内,开始
It has become an important method to study the complicated problems in science and technology by using computer numerical calculation.This paper presents two numerical examples of the more complex mechanical problems using numerical methods.1 Two vibrator system motion [1] studied the motion of objects in the double-vibrator spring system shown in Fig. 1. In Fig. 1, the mass of blocks A and B are equal, and a horizontal constant force F is applied to block A , Block B long enough to be placed on a level surface, all contact surfaces are smooth, light spring is at the original length, the movement is always within the elastic limit, the beginning
