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 electric inertia simulator stand and an electric inertia simulating control method of the ventilating disc type brake electric inertia simulator stand. The method includes the steps of synchronously collecting the rotating speed of a flywheel and the output torque of a motor, calculating total energy which needs to be compensated by the motor according to a mathematic model, calculating total energy which has been compensated by the motor at the same time, obtaining the difference between the two types of total energy, and calculating and setting a torque output value of the motor according to the difference so that the simulator stand runs under the situation where the simulator stand approaches an ideal flywheel and no system inherent resistance exists. The mechanical and electrical integrated system has an automatic compensation function for an energy compensation error, controls the total errors within a very small range, achieves accurate matching of rotation inertia and saves investment and running cost, wherein the control precision can meet high-precision test requirements.

Description

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