门式起重机多用在工厂、港口、钢铁运输等场合,频繁发生的事故引起人们的高度重视,究其原因,大多是因为载荷运动没有得到有效的控制。对其运动进行有效控制必须建立合理的动力学模型。根据动力学原理建立门式起重机的动力学模型,借助MATLAB对模型进行仿真,该模型可以较为合理的模拟门式起重机的运动特性。 Gates used in factories, ports, steel transport and other occasions, frequent accidents caused by people’s attention, the reason, mostly because the load movement is not effectively controlled. To control its movement must establish a reasonable kinetic model. Based on the principle of dynamics, the dynamic model of gantry crane is established, and the model is simulated with MATLAB. This model can simulate the movement characteristics of gantry crane more rationally.
