应用机械网络及阻抗方法分析起重机动力学

Analysis of Dynamics in Cranes by the Method of Mechanical Networks and Impedance

应用机械网络及机械阻抗方法,可以较简便地求出起重机系统中各点的位移,进而可求得各元件所承受的动载荷。本文将首先画出起重机起升机构及运行机构系统的机械网络图,按照Kirch-hoff定律列出Laplace变换的矩阵方程式,然后解出这些点的位移和这些点零件承受的动载荷。

It is simple and easy to solve the displacement of every point in the cranes by the method of mechanical metwork and impedance. Therefore we can obtain the dynamic load being supported by every component. At first, the graph of mechanical network of elevatory mechanism or moving mechanism is drawn. Then we obtain the matris equation in Laplace's transformation by Kirchhoff's law. The displacements and dynamic loads of these parts are solved from matris e- quation, which gives a reference to design or research.
