Abstract

The invention belongs to a mechatronic system, and relates to electrical drive simulation of a mechanical rotary inertia system and simulation of braking torques of other braking systems rather than a tested brake in a composite brake state, in particular to a brake electrical inertia simulating test table and an electrical inertia simulation control method thereof. Through synchronous acquisition of a rotation speed of a flywheel and the braking torque of the tested brake, the angular velocity of a motor at the moment is calculated according to a mathematical model and accordingly determined, so that the test table works in a state that the test table approaches an ideal flywheel and a test table system does not have an inherent resistance. By the brake electrical inertia simulating test table and the electrical inertia simulation control method thereof, exact match of a rotational inertia can be achieved and the control precision can meet a high-precision test requirement.

Description

technical field [0001] The invention belongs to an electromechanical integration system, and relates to the electrical transmission simulation of a mechanical rotary inertia system and the electrical transmission simulation of a composite brake, in particular to a brake test bench and an electrical inertia simulation control method thereof. 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] The mechanical simulation of the load is realized through the flywheel. Since the moment of inertia of the flywheel or the flywheel set is fixed or 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] Due to the influence of mechanical friction and wind resistance during operation,...
