This paper describes a novel 2-DOF parallel spherical mechanism named as RR&PRR. This kind of parallel mechanism is composed of two legs and fully decoupled. In this paper, the spatial model of RR&PRR mechanism is established by employing the non-dimensional method to design mechanisms. And the method of describing the performance indexes of velocity is given. Also, a novel method to describe...
In this paper, the spatial model of a novel 2-DOF spherical parallel mechanism named as RR&IILR is established by employing the non-dimensional method to design mechanisms. The method of describing the performance indexes of velocity is given. Also, a novel method to describe the mechanism's velocity performances by using the mean value of performance indexes and its fluctuation is proposed. And...
