- Abstract
In order to test the mid-strain-rate, a specialized fixture that can be installed on the MTS809 test machine is designed. A three-dimensional solid model of the fixture was established with SolidWorks, and multi body dynamics simulation analysis on the tensile process of dumbbell shaped flat specimens was carried out in the strain rate range of 1s-1~500s-1 by in ADAMS, then the collision cushioning impact pad block and an inner end cover of the contact force, the deformation velocity and deformation under given constraint condition and stretching velocity were obtained. Finite element analysis is carried out on the main components of the impact force by Workbench ANSYS basing on the conclusions obtained from ADAMS, then the deformation characteristics and stress distribution of impact block, inner end cap and fastening screw are obtained and the modal analysis of the whole fixture is carried out. Results indicate that 1.the fixture meets the design requirements and is able to conduct the whole acceleration - collision - deceleration - uniform tension test procedure, and transfer the kinetic energy to the tester; 2.the maximum stress and deformation of the important parts are all in the range of the material, thus no plastic deformation occurs; 3.there's no resonance in the stretching process.
