Conveyors are important equipment in the painting shop. Conveyors with cantilever beams have low load-carrying capacity and can carry small cars. To solve this problem, this paper presents a novel conveyor that uses redundantly actuated parallel manipulators. A method is proposed to obtain the maximum dynamic load-carrying capacity of the conveyor by optimizing the internal forces of the redundantly...
The force cueing algorithm is a primary source of flight simulation fidelity for dynamic seat. This paper presents a new optimal force cueing algorithm which incorporates a mathematical model of human body pressure system and otolith system. Linear perceptual models of the pilot in both dynamic seat and aircraft are built, then the cueing algorithm is derived by optimizing the mean-square error between...
This paper deals with the dynamics and control of a planar 3-DOF parallel manipulator with actuation redundancy. According to the kinematics of the redundant manipulator, the inverse dynamics is derived by using the virtual work principle, and the driving force is optimized by utilizing the least-square method. Based on the dynamic model, a position and force switching control strategy is proposed...
This paper addresses the dynamic modeling of a novel 3-PSP 3-DOF spatial parallel manipulator, which is used as a tool head for high speed machining of structural aircraft components. Hereby, the dynamic analysis of the manipulator is very important. Based on the kinematic analysis, the dynamic equation without considering parasitic motions is derived by using the Newton-Euler approach. Since the...
