利用铸造模拟软件Pro CAST对新型Fe-W合金应力框件在3种不同浇注温度、浇注速度和砂型预热温度下进行了铸造应力场模拟,得到铸件的应力分布情况,并对模拟结果进行了分析。分析了铸件位移最大节点处的位移随浇注温度、砂型预热温度和浇注速度的变化。设计L9（34）正交试验对铸件残余应力、位移和砂型预热温度、浇注速度、浇注温度的关系进行了探讨,并分别采用单因素分析法和极差分析法对模拟结果进行了分析,结果表明:砂型预热温度对残余应力和变形影响较大,砂型预热温度越高,铸件残余应力越小,变形越小;浇注温度对残余应力影响次之,对变形的影响最小,浇注温度越高残余应力越大,变形越大;浇注速度...

The numerical simulation of stress field in stress frame casting of the new iron-tungsten alloy in solidification process was carried out by casting simulation software-Pro CAST,with three different pouring temperatures,three different casting speed and three different sand mould preheating temperature,respectively.The stress distribution of the casting was obtained,and the simulation results were analyzed.The changes of maximum node displacement position with the cooling temperature,preheating temperature and casting speed were analyzed.The re...
