Abstract: The numerical simulation of squeeze casting to right motorcycle crankcase,as a object of study, has been performed ，based on finite element analysis software on casting and orthogonal test method.Firstly,the three feeding technology parameters, feeding pressure,feeding delay and dwell time, were confirmed by calculation and analysis after the forecast of shrinkage defects location,then,orthogonal test and test program optimization to the parameters were completed. The results show that the deeding effect was the best when the parameter values , respectively,were 190Mpa,7.5s and 12s.

Abstract: Casting process of the gearbox shell of a drill is simulated based on different technological conditions by analysis software ProCAST and orthogonal experiment method. The optimizing target is the shrinkage. It can be concluded that the factors that affect shrinkage are casting temperature, casting velocity, mold initial temperature and the cross-sectional area of inner gate in the gating system. Through analyzing the diagram of factor levels influent trend which is described according the last simulated results, the most optimized process parameters scheme is got, and the process scheme is simulated.

Abstract: For the excellent characters such as lightweight, high ratio-strength, high rigidity and reuse, magnesium alloy is used widely in vehicle lightweight redesign. Selecting AM60B as material, the process of magnesium alloy material substitution redesign for wheels of electric bicycle is advanced. The structure of aluminum alloy wheel is chosen as prototype structure for magnesium alloy wheel according to the similarity between the properties of aluminum alloy and magnesium alloy. The structure redesign optimized parametric model is put forward by the stimulation analysis of static load test and dynamic bending fatigue test. The inspection of samples shows that the structure redesign is feasible, and the target of wheels lightweight redesign is achieved.
