Vertical Vibration Characteristics of Traction Elevator Car
The study of vertical vibration of lift is the key to improve the performance of the lift,based on the traction ratio of 2:1 lift system,establish the dynamics model in the vertical direction,analyse the influence of parameters such as car load and lifting height on the car vibration and the harmonic response and inertia force response of the system when the parameters change,and study the change of dynamic load coefficient of the lift braking.The experimental results show that the traction machine is also an important source of lift car vibration,and the car vibration is directly proportional to the load mass and lifting height.
