Network optimization information:

Virtual prototype technology is a new engineering technology. The three-dimensional model of the mechanical system can be established on the computer to simulate the motion and dynamic characteristics of the system in the real environment, OMT hydraulic cycloid motor It is based on the dynamic motion model of the object as the core, supplemented by other relevant models. In the hydraulic system, because the elastic deformation of some parts in the axial piston motor has nonlinear inertial coupling, it is very time-consuming to design and optimize the motor using traditional testing methods and theoretical analysis methods, and the analysis results are often inconsistent with the actual situation. However, the analysis method of virtual prototype is completely based on the most essential factors of the object to model, and its dynamic characteristics are very close to the physical prototype, so the simulation evaluation of virtual prototype can replace the design performance evaluation of physical prototype. According to the dynamic relationship of the axial piston motor, combined with the liquid-solid two modeling methods, a virtual prototype with real-time communication between the two models was established for the simulation of the axial piston motor. The German Aachen University of Technology uses the hydraulic system simulation software DSHplus and the multi-body dynamics simulation software ADAMS to conduct joint simulation. The mechanical module is based on the physical model and dynamic relationship in ADAMS, OMM cycloidal hydraulic motor The hydraulic module is used to calculate the pressure parameters generated by the fluid, and the friction module is used to calculate the friction force, which can be connected through multiple modules Close the main friction pairs of the simulation pump. This idea of virtual prototyping has great inspiration for future research.
