Abstract

The invention belongs to mechatronics systems, and relates to electric drive simulation of a mechanical rotation inertial system, in particular to an electric inertia tyre braking bench and an electric inertia control method thereof. Drum rotation speed and motor output torque are synchronously collected, a motor torque output value is calculated according to a mathematic model, and the braking bench operates under the state that an ideal drum is close and system proper drag does not exist. Precise matching of rotational inertia is achieved, control precision can meet the requirement of a high-precision test, and investment and operation cost are saved.

Description

technical field [0001] The invention belongs to an electromechanical integration system, and relates to an electric transmission simulation of a mechanical rotary inertia system, in particular to an electric inertia tire braking test bench and an electric inertia control method thereof. Background technique [0002] In the bench test of tire braking, it is necessary to test the braking performance of the brake under different conditions, the essence of which is that the brake consumes 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 drum. Since the moment of inertia of the drum is fixed, it is impossible to simulate the load accurately all the time. This problem can be well solved by the simulation of the electrical inertia. [0004] The braking torque of the tire brake is composed o...
