On this basis, Germany's Yashen University of Technology has established an experimental platform for friction pairs based on the idea of mode pump and carried out relevant research. Cabin opener hydraulic motor The test method of the model motor is close to the reality, and the results can better reflect the actual operation of the motor, which is of great significance to the design and optimization of the motor and new structure.

During the development of the axial piston motor, the three friction pairs of the plunger pair, the port pair, and the contact pair between the plunger and the swashplate (mainly the slipper structure at present) have not changed much. Oil suction, oil pressure and flow distribution are important links for the engine to complete its work, and are also the main places for oil consumption, oil leakage and leakage. The performance and life of these friction pairs are closely related to the engine. Therefore, they should be modified and optimized, 530 cycloidal hydraulic motor It becomes one of the key technologies of axial piston engine. Professor MONIKA of Purdue University in the United States revealed the distribution law of friction force on different shapes of plunger by studying the oil film dynamics, friction force and energy dissipation at the clearance of plunger pair, and concluded that the plunger is not the shape of plunger under the friction state, and proposed that the plunger has a more complex micro movement in the plunger cavity, The fretting model for solving the plunger wrist force state is also verified by the corresponding experiments.
