Research on Vibration Behaviors Simulation for a Novel High-Speed PMT

Abstract

In order to grasp the vibration characteristics of a novel High-Speed 4-HPS-HPH PMT(parallel machine tool), A vibration behaviors analysis method using virtual prototype simulation was put forward. By the united application of CAD, CAE and visual technologies, the rigid-flexible vibration model of 4-HPS-HPH PMT was constructed. Then the dynamic response of the tool tip, including vibration displacement, vibration velocity, vibration acceleration, and maximum dynamic stresses of driving limbs were realized. The simulation results show that the rigid-flexible vibration model proposed can indicate the vibration behaviors of parallel machine tool. This research provides necessary guidance for dynamic performance analysis, optimization design and control of this 4-HPS-HPH PMT.

Elastic Dynamics Optimization Design of Novel High-Speed Spatial Parallel Robot

“…The high-speed parallel robot, as a type of new-structure manufacturing equipment, has been used in many applications, such as automation, light industry, assembling robots, etc [1][2]. In high-speed and high-acceleration conditions, due to the geater external and internal loads, the deformations of the links casuse strong vibration situation in real working, and lead to reducing motion precision and stability of the parallel robot.…”
