The invention discloses a device for testing friction characteristic of a hydraulic cylinder for engineering machinery and a guide rail. The device comprises a detected hydraulic cylinder, a loading hydraulic cylinder, a docking mechanism, a tension and pressure transducer, a spoke-type force transducer, a slide block, the guide rail and a displacement sensor, a piston end of the loading hydraulic cylinder is connected with the spoke-type force transducer, the other end of the spoke-type force transducer is connected with the docking mechanism, the other end of the docking mechanism is connected with a piston of the detected hydraulic cylinder, the tension and pressure transducer is connected with the outboard of the spoke-type force transducer on the docking mechanism in a detachable mode, and the other end of the tension and pressure transducer is connected with the slide block. The device for testing friction characteristic of the hydraulic cylinder and the guide rail has the advantages that operation is convenient and easy, and tests can be carried out on the frictional force parameter of the hydraulic cylinder and the guide pair simultaneously.
Description
technical field [0001] The present invention relates to an experimental device for testing dynamic friction parameters of engineering machinery hydraulic cylinders and guide rails and a testing method thereof, in particular to an experimental device capable of testing dynamic friction parameters of joint surfaces of engineering machinery hydraulic cylinders and sliding guide rails at the same time. testing method. Background technique [0002] Hydraulic cylinders and guide rails are widely used components or components in construction machinery systems. The friction of the joint surface of the hydraulic cylinder or guide rail assembly directly affects the positioning and motion accuracy of the mechanical system where it is located. Due to the lack of measurement and modeling of friction, the problem of inaccurate positioning of hydraulic system actuators often occurs. Therefore, it is necessary to invent a simple, feasible and accurate experimental device and testing metho...
