摘　　要：在分析塔式起重机载荷摆动特性的基础上,将载荷摆动非线性动力学模型进行线性化处理,推导出载荷摆动表达式,并应用Matlab软件进行了载荷摆动特性仿真。在VC环境中利用Vega的函数编程实现载荷摆动,在虚拟操作系统中真实再现载荷的运动特性和摆动特性,增强了塔式起重机虚拟操作系统的真实性。Based on the analysis of characteristics of tower crane load swing, linearization is made on the nonlinear dynamics model of load swing, the load swing expression is deducted and the emulation of load swing characteristics is performed with Matlab software. The load swing is realized with Vega Functional Programming in VC, load motion characteristic and swing characteristics are made in reality in a virtual operating system and the trueness of the virtual operating system of tower crane is strengthened.
