High-power output inertia tester

Abstract

The invention relates to a high-power output inertia tester. The high-power output inertia tester comprises a variable frequency motor (1), a motor coupler (2), a motor end short shaft (3), an electromagnetic clutch (5), sliding bearings (6), a fragment detachable fly wheel set (7), a fly wheel main shaft (8), a hydraulic clutch (9), an output end short shaft (10), a torque and rotating speed sensor (11), a diaphragm coupling (12), a tester output shaft (13) and a hydraulic clutch hydraulic system (16). Fly wheels of the tester can load different inertia combinations according to test needs, supply needed accelerating torque to fast accelerate tested equipment to the appointed rotating speed and keep constant-torque or constant-rotating-speed output of the output shaft within a short time by controlling the clutch. The tester is large in output torque, high in power and response speed, stable and accurate, and can be used for testing the dynamic property of starting, with loads, of the high-power mechanical equipment and used for calibrating the damping coefficient of a tested brake device.

Description

technical field [0001] The invention relates to the field of flywheel energy storage, in particular to a high-power output inertia test device. Background technique [0002] In large-scale heavy industrial machinery and equipment, some high-power mechanical energy-consuming equipment or actuators have dynamic response requirements during on-load starting. Whether the dynamic performance parameters such as torque, maximum acceleration capacity and rise time meet the technical requirements, and at the same time check whether the strength of each component of the equipment meets the design requirements. [0003] In order to meet the requirements of equipment performance testing, the test device is required to provide power for the equipment under test, and can output high power energy in a short period of time to accelerate the equipment under test to the specified speed and torque state, and test the equipment according to the specified test speed and torque. The startup proc...

Problems solved by technology

[0005] In the field of aviation industry, the test bench for testing the performance of aircraft brakes and tires uses tires to directly mesh with the flywheel, and the friction between the tire and the flywheel acts as a clutch to transmit torque during the meshing process, but the biggest shortcoming of this test bench is the flexible body of the tire. In the process of torque transmission, it is easy to slip with the metal flywheel, and the torque that the tire can transmit is small

It is difficult to meet the test requirements of high-torque equipment above 150,000 Nm
