In an elevator system, if the machine or pulleys (sheaves) have some faults, the vibration will occur to the car. However, it is not easy to investigate the quantitative relationship between cause and result. In this report, we construct a dynamics model and clarify the relationship between the vibration of the car and the amount of disturbance caused by the core dislocation of the encoder and torque ripple of the motor through some experiments and simulations.
