    Abstract:

    Based on the design theory and methodology of parallel mechanisms (PM) based on position and orientation characteristics (POC) equations, a two-translation-rotation (2T1R) PM was designed. It consisted of low pairs and possesses symbolic forward solutions as well as partial motion decoupling. The primary topological features of the PM, including POC, degree of freedom, coupling degree, and motion decoupling were analyzed. Subsequently, based on the kinematic modeling principle derived from topological characteristics, symbolic position forward and inverse solutions for the PM were obtained. Simultaneously, singularity analysis was conducted by using the inverse position solution while solving for the workspace of the PM based on symbolic solutions. Furthermore, employing a sequential single-open-chain method grounded in virtual work principles enables dynamic performance analysis of the PM along with calculation of actuated forces exerted on its three driving pairs. The maximum driving forces required for the three sliders were -58.52N, 47.28N and 64.10N, respectively. Ultimately, this PM can be utilized as an end-effector and safety lander for UAVs; their conceptual design was elaborated upon. The research can provide a theoretical basis for kinematics and dynamics modeling and analysis of 2T1R parallel mechanism symbolized by positive solution and kinematically decoupled, as well as mechanism performance optimization and prototype development.
