计算机仿真方法在冷库电梯系统的应用研究

Application of Computer Simulation to an Elevator System of the Cold-storage

通过建立某电梯系统的动力学模型及状态方程,设计了一个具有普遍意义的仿真程序并利用此程序对电梯实例进行提速改造的模拟仿真,结果呈现低衰减率自由振动形态,有关参数均满足GB10058-1997和ISO2372等规定的要求;同时计算出系统固有频率的取值也在许可范围.从理论上论证了改造电梯是安全可靠的.

Through building a dynamics model and state formulas of an elevator system, a simulation programme of universal significance is designed. Simulation results show that vibrations are low attenuational forms and all parameters meet completely the requirements of GB 100581997, ISO 2372, etc. Meanwhile, reckoned intrinsic frequencies are under control, which theoretically proves that the speededup elevator runs in a safty state.
