Abstract: |
Aiming at the characteristics in the loading test, combined with the problems and defects that appear in the loading test process of previous similar products, the loading characteristics and test requirements are researched carefully. The idea that applying the pull rod to tensile load testing have been advanced boldly and skillfully, and a suit of appropriative process equipment is designed. Then the structural of equipment is analysed by three-dimensional simulation, and the strength and stiffness of equipment is worked out by the means of finite element analysis method. The results demonstrate that the equipment ultimately satisfies the product loading requirements, and the experimentation is simple, convenient and accurate. |
