Electrical inertia simulation ventilated disc brake test bench and electrical inertia simulation control method

Abstract

The invention belongs to an electromechanical integration system, relates to braking torque, synchronous measuring combined braking torque and mechanical friction braking torque of other braking systems except a tested brake under electric transmission simulation and simulation combined braking state of a mechanical rotation inertial system, in particular to an electric inertia simulation ventilation disc brake test bed and an electric inertia simulation control method. By collecting flywheel rotational speed, motor output torque, and tested brake combined braking torque, the overall energy required to be compensated by a motor can be calculated according to a mathematical model, meanwhile, the overall energy compensated by the motor is calculated, and the difference between the overall energy required to be compensated and the overall energy compensated is obtained, therefore, torque output value of the electric motor is calculated and given, so as to enable the test bed to be close to an ideal flywheel and run under a state without inherent system resistance. The electric inertia simulation ventilation disc brake test bed has an automatic compensation function for compensating errors, thereby enabling the total error to be controlled within a very small range; accurate matching of the rotary inertia is achieved, and the control accuracy can met the requirements of high-precision test; investment and running cost are reduced.

technical field [0001] The invention belongs to an electromechanical integration system, and relates to the electrical transmission simulation of a mechanical rotary inertia system, the electrical transmission simulation of a compound brake, and the measurement of the combined braking torque of a ventilated disc brake and the mechanical friction braking torque, especially the electrical inertia simulation of a ventilated disc. Type brake test bench and 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 i...
