钢绳罐道上容器的摆动和晃动

本文研究了钢绳罐道上提升容器的横向运动,它包括容器质心的横向摆动和绕质心的转动。建立了此系统的动力学微分方程组,并用龙格——库塔方法求得了运动的数值解。通过对数值解的分析说明:(1)容器的摆动量与提升钢绳的横向力,以及罐道长度成正比,与重锤的重量成正比。(2)在容器长度确定的条件下,增大上下罐耳之间的距离可使容器的晃动减小。但是,如果容器长度与罐耳间的距离同步地增加,将不能达到使晃动减小的目的。

Oscillating and Shaking of a Container Along the Rope Guides

In this paper, we discussed the lateral motion of a container along the rope guides. The motion of a container compressed two parts: the oscillation of the center of mass and the rotational vibration round that center of mass.For this dynamic system, the differential equations are established, and determined the numerical solutions by Rung-Kutta method,Analysed these solutions find that ( 1 ) The amplitude of the oscillation of container is proportional to the lateral force given by hoist rope, and it is also proportional to the length of rope guides, but is inversely proportional to the weight. (2) If the length of container is kept constant, increasing the distance between two ears of cage, then the shaking of container will decreases. But, if the length of container and the distance between two ears of cage are increasing similarly, the shaking of container can not decreases.
