Tips: Application of stepper motor in car testing
As for testing of numerous car braking elements, booster assembly of brake master cylinder in hydraulic brake system and brake vale in pneumatic brake system, it is necessary to use ball screw of motor drive in the test system to simulate the actual braking process of car brake by stepping on the brake pedal. Ball screw drives the master cylinder brake valve to reach various working conditions necessary for car brake so that various performance indexes can be tested. Meanwhile, there is no accumulated error in stepper motor during its motion the following performance is good as the angular displacement is in strictly and direct proportional to the input pulse. Therefore, the stepper motor is the actuating element with good performance in car brake element test system. System hardware is comprised of displacement sensor, force sensor and stepper motor. The IPC and data acquisition card is used to control core.Stepper motor drives ball screw through coupler to constitute augmentor; install force sensor on front end of screw mandrill to measure “input force of the test piece” of the output torque of stepper motor, control the start, forward and backward, stop of the stepper motor with IPC, and control the forward and backward speed according to the test program, measure the displacement of the stepper motor with displacement sensor, and indicate corresponding data of force and displacement through display, and then judge whether the air brake valve is qualified or not according to the related industrial standard.
