Embodiment Construction
[0041] like figure 1 As shown in the figure, the electric inertia simulation brake test bench includes at least a torque sensor 1, a drag motor 2, a speed sensor 3, an electric inertia simulation control unit 4 and an electric transmission control unit 5; A torque sensor 1 is installed between 6 and the drag motor 2 to measure the braking torque of the brake under test. The electric motor 2 runs to the set speed and starts the braking process; the electric inertia simulation control unit 4 obtains the braking torque and angular velocity synchronously collected by the torque sensor 1 and the speed sensor 4, and the electric inertia simulation control unit 4 calculates the motor according to the mathematical model. The calculated angular velocity at this time is given accordingly, so that the test bench operates in a state where the ideal flywheel is approached and there is no inherent resistance of the system.

The invention belongs to a mechanical-electrical integration system, relates to electric transmission simulation of a mechanical rotation inertia system and brake torque of other brake systems except a tested brake under the condition of simulating hybrid brake, and particularly relates to an electric inertia simulation brake tester and an electric inertia simulation control method. The calculation rotating speed of a motor at the moment can be calculated and can be determined according to a mathematic model by synchronously collecting the rotating speed and the brake torque of the tested brake, and thus the electric inertia simulation brake tester can be operated under the conditions that the electric inertia simulation brake tester approaches an ideal flywheel and the proper drag of a tester system does not exist; the accurate matching of rotation inertia can be realized, and the high-accuracy test requirement can be met by the control accuracy.
Description
technical field [0001] The invention belongs to an electromechanical integration system, and relates to the electric drive simulation of a mechanical rotary inertia system and the electric drive simulation of a compound brake, in particular to an electric inertia simulation brake test bench and an electric inertia simulation control method. Background technique [0002] In the bench test of the brake, it is necessary to test the braking performance of the brake under different conditions. Therefore, the brake test bench should have the function of simulating different working conditions. [0003] Due to the influence of mechanical friction and wind resistance, the mechanical system of the test bench will generate the inherent resistance torque of the system during operation, which will affect the test accuracy. Therefore, the interference of the inherent resistance of the test bench system should be excluded in the control process. [0004] Whether it is a train or a car, t...
