Elastic-plastic large deformation finite element is used to study the behavior of the square tubular T- joints by ANSYS software. the influence of the parameters including the position, the number, the thickness, the size of the hole of the internal stiffener and the non-dimension parameters on the joint's strength were studied, stress distribution, plastic-zone development, failure mode and ultimate...
The revolute outputs effected by the clearances of joints which are caused by the inaccurate precision of processing and error of assembly are analyzed at first, then in order to illustrate the problem the simulation of a kind of parallel mechanism named 3-PRUR is also done in Pro/E and Adams software. At last a kind of compliant revolute joint called split-tube flexural pivots based on the principle...
Arthrodesis and arthroplasty are two surgical options for the treatment of metacarpophalangeal joint disease or injuries. Arthrodesis is a fusion of the two bones which will restrict the joint range of motion. Arthroplasty involves replacing the diseased joint with a prosthesis which is preferable to arthrodesis due to the restoration of normal joint function. In arthroplasty, a hinged prosthesis...
The combination of ANSYS and ADAMS can improve the precision of system simulation. In this paper, first, a cable-stayed space truss, consisting of stay cables, columns, and the space truss, is built in ANSYS. Second, the modal neutral file (mnf) needed in ADAMS is generated by executing the macro command “ADAMS” and then imported into ADAMS software. Third, the flexible body in the mnf file is connected...
The kinematic and vibration analyses of the twin tripod sliding universal joint were carried out by using the mechanical system virtual prototype simulation software ADAMS and finite element analysis software ANSYS. Main kinematic properties and natural frequencies thereof being a theoretical basis of the following research were then obtained.
Discussed in this paper are the issues underlying the mechanical design of 7-DOF manipulator. A comprehensive solution for the structural type selecting, and the detail design of the links, the joints and the parts is introduced. First the design requirements including the workspace, manipulability, loading capacity, weight, precision, motor power etc are studied. After the preliminary design and...
