Research on Balance Optimization Design of Vestibule Function Trainer Based on Spherical 4R Space Mechanism

The human vestibule function trainer studying in this paper is based on the first generation of spherical 4R space mechanism. Using the 3D modeling software UG and its integrated simulation analysis tool UG MOTION, the spherical 4R space mechanism and its common form are used as research objects. UG software's powerful modeling ability enables 3D solid modeling of the members and main parts, completes the virtual prototype modeling, and uses UG MOTION to simulate the overall motion of the virtual prototype. By adding the balance block method, the dynamic balance optimization design is completed. Then the motion simulation is carried out, the analysis results, and the balance problem is well optimized.
