This paper implements the analysis of material and design structure of a three-fingered robot hand. In previous work, the robot hand was custom-designed for assembly work using SolidWorks software application. The robot hand consists of three 2DOF robot fingers actuated by DC micromotors and a 1DOF hand palm. In this work, finite element analysis (FEA) method is used to analyze the robot structure...
The installing and working states of coaxial OCSR assembly seal device is analyzed and studied with ANALYSIS software when the thickness of OCSR is different. The effects of the OCSR thickness changing to the contact stress on seal face and contact surface, and to the Von-mises stress on O-type seal ring as well as to the spring force are presented. The good sealing performance and the self-compensation...
This paper presents the design and fabrication process of a new piezoelectrically actuated flexure-based XYZ compliant parallel-kinematics micropositioning stage with totally decoupled properties. The proposed XYZ stage consists of three limbs which are assembled in an orthogonal manner, and it has both input and output decoupling properties. Analytical models for kinematics, statics, and dynamics...
Solid garbage crusher is one of the most important equipments in garbage coal production line. Faults of solid garbage crusher have great influence on the efficiency of garbage coal production line. To solve the problem, an improving design of solid garbage crusher is presented. The key factors that cause the faults to crusher are confirmed through the stress computation of cutting tools. An improving...
