Abstract

The invention belongs to a mechanical and electrical integrated system and relates to electric drive simulation of a mechanical rotation inertia system, measurement of braking torques of brakes except the tested brake and synchronous measurement of a combination braking torque and a mechanical friction braking torque under a simulated composite braking state, in particular to a ventilating disc type brake test stand and an electric inertia simulating control method of the ventilating disc type brake test stand. The method includes the steps of synchronously collecting the rotating speed of a flywheel and the output torque of a motor, calculating a torque output value of the motor according to a mathematic model so that the test stand runs under the situation where the simulator stand approaches an ideal flywheel and no system inherent resistance exists. According to the test stand and the method, accurate matching of the rotational inertia is achieved, control precision can meet high-precision test requirements, and investment and running cost are saved.

Description

technical field [0001] The invention belongs to an electromechanical integration system, and relates to the electrical transmission simulation of a mechanical rotary inertial system, the electrical transmission simulation of a composite brake, and the measurement of the combined braking torque of a ventilated disc brake and the mechanical friction braking torque, especially with a ventilated disc brake. Test bench and its electric inertia simulation control method. Background technique [0002] In the bench test of ventilated disc brakes, it is necessary to test the braking performance of the brakes under different conditions, the essence of which is that the brakes consume the energy set under specific working conditions. Therefore, the brake test bench should have the function of providing specific energy under different working conditions. [0003] The mechanical simulation of the load is realized through the flywheel. Since the moment of inertia of the flywheel or the f...
