Optimizing Design of Powder Compacting Process on Complex Parts using Experimental Data-based Numerical Simulations
The compaction process of powder particles and optimized design of three-dimensional complex consolidated parts were investigated via MSC-Marc software simulation based on the finite element method(FEM)which can be applied to a continuous body.First,the reliability and accuracy of the proposed FEM model were validated by comparing the experimental results with the numerical model prediction.Secondly,in order to put forward the most influential,variable and optimum compaction route,the influence of their variables on the relative density distribution during compaction was studied.Their variables include temperature,friction,compacting style,speed and time of dwell.Lastly,the search for the optimal geometry of the spur gear was carried out on the basis of the proposed FEM model and structural analysis of the resulting gear was also performed using software Workbench.Consequently,the proposed design of the spur gear is feasible.
