Research On The Key Technology Of Virtual Prototype Based On BMR Series Cycloid Hydraulic Motor

Virtual prototype technology has gradually emerged and developed to meet the needs of the machine industry.The subject will use the BMR series cycloid motor as a template to analyze its working principle in detail.With reference to the mathematical model of the cycloidal rotating stator wheel mechanism,a virtual interactive interface for the design of cycloidal motors was established to improve the efficiency of motor research and development.The main content of the research is as follows:(1)After analyzing the manufacturing process of the cycloid motor and the status quo of the industry worldwide,this paper puts forward the idea of designing a virtual simulation platform interface to simplify the motor design process.The thesis described the working principle of the shaft-distributed cycloid hydraulic motor and the movement of the cycloid meshing pair during the output shaft distribution process,thereby the parameter equation of the cycloidal meshing curve is established and the theoretical equation of the main parameters of the motor is obtained.(2)By setting the parameter input and image output windows,the theoretical expression of the parameters is used to construct the GUI design interface of the hydraulic cycloid motor,and then the effect of each size parameter on the motor performance is analyzed according to the calculation output result of the interactive interface,and draw the mathematical relationship between each size and performance.(3)Combining the force of the cycloidal rotating stator wheel mechanism,building a three-dimensional model with the help of the tooth profile curve generated by GUI,and then using ANSYS software to design a feasible stress and strain analysis method,further completing the dynamic analysis of the cycloid meshing pair in Abaqus to check the strength of the component.(4)According to the effect of elastic deformation on the model,simulation software is used to study the characteristics of the cycloid stator wheel mechanism,and the meshing force strength and the center of mass diagram are drawn,and the results are further compared.The virtual design platform is used to verify the theoretical analysis and establish the dynamic design procedure of the engine,and the guiding significance of the GUI interactive interface for the design of the cycloid hydraulic motor is finally demonstrated.
