Design And Development Of Three Degrees Of Freedom Wave Simulation Platform

Virtual motion platforms are widely used in military, lifestyle, entertainment, etc. For example, analogging spacecraft to train pilots to simulate the car running on a complex road conditions, providing immersive recreation experience and so on. Motion platforms are with lower costs, improving efficiency, etc., becoming a hot topic in today's research. With the rapid development of computer technology, computer-aided design has been widely used in various fields of society. Machinery manufacturing industry has also been widely used in a variety of CAD/CAM softwares to improve work efficiency, reduce labor intensity engineers to optimize product solutions.In this paper, three degrees of freedom wave simulation platform has been studied. On the basis of analysis of the current wave simulation, combined with the actual application requirements,we have researched and manufactured series and parallel combinations of three degrees of freedom motion simulation platform. According to the characteristics of the platform body we carried out analysis of the kinematics and dynamics,discussed the positive solutions and platform location inverse solution analytic expressions.Combined with theoretical design calculations, we use SolidWorks software to establish a three-dimensional model of the assembly after the completion of the simulation experiment, complete the simulation three degrees of freedom motion platform,and the motion platform has good athletic performance. We gOt waves platform during movement curve and hydraulic cylinder movement, verify the correctness of the kinetic theory analysis, to provide a reference for the design of the hydraulic system. On the basis of fluid mechanics and classical control theory, we established a mathematical model of the valve controlled hydraulic cylinder, and according to the principle of electro-hydraulic servo position control system structure, the mathematical model derived heave complete position control mechanism. In the hydraulic system design process, we completed a major component selection and design calculations, combined with the use of mathematical models MATLAB/Simulink software to complete the simulation, the hydraulic system can reflect the dynamic characteristic curve after simulation to verify the feasibility of the hydraulic system.
