Vibration or Noise Testing Method for Column Type Electric Power Steering

摘要

The present invention is an electric power steering having one end to be coupled to a steering wheel side, an assist motor for providing electric power according to the rotation of the steering wheel, a reducer, and the other end for transmitting power from the reducer to the wheel side It relates to a method for testing vibration or noise on a device. The test method of the present invention includes the steps of excitation with an input excitation torque using an excitation motor for an electric power steering apparatus, measuring the vibration of the electric power steering apparatus, and comparing the measured vibration data with a reference value. Evaluating an electric power steering device, wherein the excitation motor is at least one of a motor having the one end, a motor having the other end, and the assist motor.
