Abstract

The invention discloses a variable-frequency loading intelligent brake testing system and method. The system comprises an installation pedestal, and the installation pedestal is provided with a transmission central shaft, a limiting switch, and a to-be-tested intelligent brake. The transmission central shaft is provided with a braking disc; a motor and an angle coder which are in transmission connection with each other; and a twisting force limiting shaft coupler. The intelligent brake is used for braking a braking disc, and the motor is used for controlling the rotating speed of the transmission central shaft. The angle coder is used for collecting the rotating speed of the shaft. When the braking disc is braked and the generated shaft torque is greater than a limit value, the twisting force limiting shaft coupler generates shaft rotating slipping, and the limiting switch is used for collecting and judging whether the twisting force limiting shaft coupler slips, and an external control end is used for sending a command and giving an alarm. The torque sensor records the size of the torque between the braking disc and the load in the whole testing process. According to the invention, the system solves a problem of how to test the braking performances of the intelligent brake.

Description

technical field [0001] The invention belongs to the technical field of test systems, and relates to a test system and a test method for intelligent brakes based on frequency conversion loading. Background technique [0002] At present, the normally closed electro-hydraulic brake is a commonly used safety device in the industrial field. It is usually used for the braking of crane trolleys, carts, hoisting and luffing devices, the braking of wind power equipment, and the prevention of sagging of anchor chains when ships break down. Its function is to brake the moving parts according to the driver's command. [0003] Traditional normally closed brakes only have opening and closing functions, without a controllable intermediate state. This causes the brake to directly lock the brake pad when braking, which will generate a huge impact force, and also cause the local part of the brake to heat up rapidly and be damaged. In some applications, such as emergency stop conditions, it ...
