Abstract

The invention, which belongs to the mechatronics field, provides a friction loading apparatus and a method thereof. The apparatus comprises: a hydraulic pump station, a brake mechanism and a measurement and control system. The brake mechanism comprises: a rotating shaft, a brake disc and two groups of brake calipers. Each group of the brake caliper comprises one brake pad and two brake pistons. The method comprises the following steps: firstly, correctly installing a tested system on a test station; then through the measurement and control system, starting the hydraulic pump station, adjusting a system test pressure so that hydraulic oil drives the brake pistons to move towards a direction of the brake pads and the brake pads are extruded, generating a loading force because of the friction between the brake pads and the brake disc and real-timely calculating the friction loading force through the hydraulic oil pressure; finally, reducing the system test pressure through the measurement and control system so that the friction force of the brake pads and the brake disc reduced to zero. By using the apparatus and the method of the invention, the tested system can be applied with the friction load corresponding to an actual condition. Actual performance of the tested system can be reflected. An apparatus structure is simple and application is convenient.

Description

technical field [0001] The invention relates to a friction loading device and method, belonging to the field of electromechanical integration. Background technique [0002] In order to truly reflect the actual performance of the system under test, it is necessary to simulate the actual working environment under laboratory conditions, and apply a load corresponding to the actual working conditions to the system under test. [0003] The loads on the tested system under different working conditions are very complex, including frictional load, inertial load, elastic load, unbalanced load, time-varying load and shock load. [0004] For the friction load of the tested system, there is no relevant loading device and method at present. SUMMARY OF THE INVENTION [0005] The purpose of the present invention is to provide an equivalent friction load to the tested system, and to propose a friction load device and method. [0006] A friction loading device of the present invention in...
