| 摘 要： | 电梯的绝大部分事故都出在门系统上,而门机系统的摩擦力和摩擦系数是反映门机性能的重要指标.建立了电梯门机系统的动力学模型,通过模型计算的加速度和传感器实测的加速度进行比较获得误差函数,对其优化查找最小值,与最小值对应的未知量为门的倾角力和摩擦力,进而计算出反应门机性能指标的系统摩擦系数,为研究电梯门机性能和系统智能维护打下基础.

| Abstract: | Most of the accidents of the elevator happen on the door system,the main specifications that reflect the performance of elevator door system include frictional force and friction coefficient. A dynamic model of the door system was built,According to the comparison of the calculated acceleration and measured acceleration,an error function is obtained,whose minimum value is found. The unknown parameters corresponding to the minimum value are tilt force and frictional force,then,friction coefficient that refle... |
