| The 6-DOF motion simulator is a test equipment which can be used to study dynamic performance and reliability of airplane, vessel, spaceflight, vehicle and so on. It also can be used to train pilot, sailor and vehicle driver. With the deep research of scientists, its application field becomes more and more wide. Now the range of its application is expanding continuously with extensive prospect on the field of automotive industry, aviation, spaceflight, shipping, vehicle, robot, machine-tool industry and amusement.This paper studies the kinematics analysis and dynamics analysis of the 6-DOF motion simulator. Kinematics analysis mainly studies the position analysis, including the inverse kinematics and the forward kinematics, and how to calculate the pose of the platform, and how to calculate the velocity and acceleration of the actuator. Dynamics analysis studies the force of the actuator by the Newton-Euler approach, the force was created by motion parameter.The performance of the 6-DOF motion simulator has close relationship with geometric parameters. The purpose of optimization is to get a set of optimal parameters for getting the demanding of function and performance. This paper studies the practical-way about parameter optimization of the 6-DOF motion simulator, the practical-way is the search method of parameter-subsection-compages.This paper studies the interference of the 6-DOF motion simulator, and plots the distribution map of angle between actuator and joint, and calculates the angle between actuator and platform. All the results offer the assurance for no-interference.This paper studies the digital prototype system, and get the fast-way from structure parameter to simulation. The digital prototype system can prove the result of optimization.This paper illustrate the optimal design though an example. It proves the feasibility and correctness of the optimization and interference -analysis and fast-simulation. |
