Description
technical field [0001] The invention relates to a tangential fretting wear test device driven by a voice coil motor, which belongs to the technical research field of tribology in mechanical engineering. Background technique [0002] A voice coil motor is a device that converts electrical energy into mechanical energy and realizes linear or circular motion. Compared with other servo motors, voice coil motors have high response frequency and fast response speed (millisecond level), and are especially suitable for motion systems with small strokes, high precision and high response frequency, and can perform high-speed oscillating reciprocating motion (up to tens of hertz) ), and the control of the voice coil motor is simple and reliable, no reversing device is required, maintenance-free, long life, and can work continuously for a long time. Its accuracy depends on the feedback and control system. With proper position feedback, the positioning accuracy can reach 10um, and the a...
