Double axis fatigue life prediction based on finite element analysis for aluminum alloy wheels
The basic situation was introduced firstly on the wheel double axis fatigue (abbreviated to WDAF) testing. Then the basic process to carry out the finite element analysis and the fatigue life prediction on the WDAF testing were introduced briefly. Subsequently, a typical wheel was taken as an example to implement the finite element fatigue life prediction for the WDAF testing of the aluminum alloy wheel. Finally, an initial criteria was proposed for the WDAF life prediction based on the analytical results from FEA for several wheels.
Prediction of automobile wheel fatigue life with improved smith equation
Presents Smith equation improved to include the causes having deep impact on high cyclic fatigue life prediction and the eight grade carrying table coming from LBF research department used to simulate the running state of the wheel, and the calculation of wheel fatigue life in runninging states with improved Smith equation and parameters resulting from finite element analysis.
SR topography of plastically deformed Fe-Si bicrystals - observation in situ and post mortem
SR reflection topography was applied to study the interaction of slip dislocations with the grain boundaries in Fe-4at%Si bicrystals deformed by compression. Three experimental settings with either a white or monochromatic beam were used and the corresponding orientation contrast analysed. Dislocation transmission through the grain boundary was observed in bicrystals with favourable geometry of the slip systems.
