Modal superposition analysis was used in the calculation of crankshaft dynamic strength and fatigue life based on rigid-flexible multi-body system dynamics analysis and finite element analysis, this paper verified the precision of crankshaft finite element modal by experiment modal analysis, resulted the position of max stress and dynamic variation during the engine working, calculated the dynamic...
In order to establish the finite element model of the knee-joint, force analysis applies on the knee-joints of persons are done first. The CT scanning images of a normal male volunteer's upper end of tibia are adopted, which are processed by Mimics 13.0 software to calculate a 3D model. Surfaces of the model are dealt by Geomagic 9.0 software and a smooth shell model is constructed. At the same time,...
In this paper, the voltage-sharing performance of MOA (metal-oxide surge arrester) for 1000 kV UHV GIS is discussed using the secondary development of the finite element and boundary element numerical method by 3D simulation, ensuring the non-uniform rate of the voltage distribution can be controlled within 10%, reaches the requirements of electric field distribution and the voltage distribution on...
