运动载荷作用下的悬索动力分析

DYNAMIC ANALYSIS OF THE TELPHER UNDER THE ACTION OF MOVING LOAD

通过计算悬索的阻尼效应和运动载荷的质量、惯性力，研究了货车通过索道时整个过程的动力计算问题．用小参数法求出了单个运动载荷作用下的索道动力方程的一般解，建立了多个货车通过索道时的动力方程．结果表明，小参数近似解与离散的数值解相比，具有连续性、解析性和计算量小等优点，便于系统分析问题的性态。对无阻尼问题的一阶结果也进行了讨论．

The dynamic calculation of whole moving process of a cable carriage through the telpher is studied in consideration of the damping effect of the cableway, mass and inertial force of the moving load. The general solution of dynamic equation for the cableway under the condition of a single moving load is obtained by means of the small parameter method.Dynamic equation for the multiple cable carriages passing through the telpher is also set up. The results of the non-damping condition are discussed. The approximate solution is of the advantages of continuity, analyticity and minor computation..
