Research on high-speed elevator MDOF horizontal dynamic characteristics and simulation

Elevator horizontal dynamic characteristics has a greater impact on the high speed operation elevator.Based on the horizontal vibration analysis of high speed elevator car,the important factors as rail irregularity,rail curve and the defect of guide shoes themselves were converted into the contact force of the rail to the guide shoes.Having taken the driving forces generated during the operation process in the rail length direction into account,the multi freedom horizontal vibration model of high speed elevator car was established.Then,through MATLAB simulation,the dynamic model curve of horizontal vibration model of high speed elevator car was obtained,which has much higher fitness with that of measured horizontal vibration curve of high speed elevator car,having proven that the modeling method is correct and practical.
