径向锻造工艺参数对锻透性的影响
Effects of Process Parameters on FPE in Radial Forging Processes
摘要
Abstract
By projecting the hammer of the radial forging process to a unit cylindrical surface ,con‐straint conditions should be fulfilled by the parameters :radial feed rate and the axial feed rate were ob‐tained after analysis .The relationship among the empirical triangle criterion and the processing param‐eters in radial forging process was derived ,the effects of the parameters on FPE was analyzed .FEA software MSC .Marc/Mentat was used to simulate the radial FPE in radial forging process .Equivalent strain should be larger than the critical value and the axial compressive stress criterion were adopted in the simulation ,and the simulation results were compared with the results of the empirical criterion of FPE prediction .The comparison shows that the empirical method is suitable for radial forging process design .Also ,the calculation results of the process parameters are approximate accurate in estimating the FPE of radial forging process .关键词
