在溫度場的模擬中,模擬結果表明,保壓時間是影響製件成形質量的關鍵因素之一,擠壓速度、液態金屬澆注溫度、預制體預熱溫度和模具預熱溫度等工藝參數對溫度場的影響也很大,需進行參數之間的協調,只有當變形區內部始終維持準固態時,才能實現穩定的液-固擠壓成形過程;在變形場的模擬中,根據液態浸滲擠壓的成形特徵,選用了雙曲正弦剛-粘塑性有限元計算模型,研究了變形過程中應力應變場的變化規律,研究了模角對變形和金屬流動的影響及變形力的變化過程和其影響因素。By successful solution of non - linear magnetic fields and revision of the program, we can reach following conclusions : in the computation of nonlinear magnetic fields, if iteration method is used, under - relaxation is necessary when amending the permeability distribution in soft magnetic materials ; and when < wp = 5 > calculating the equivalent current density in permanent magnets, under - relaxation is not a necessity ; when searching for permeability values by interpolation method on the demagnetization curve of soft magnetic materials, if a fixed saturation point is set, around this point an abrupt change of permeability values will be obtained ; this sudden change may cause a little problem in the smoothness of magnetic field distribution ; because the magnetic circuits of microwave tubes are too complicated, in the author ' s view, to describe the working state of a magnet system, the working points of magnets can not do it properly but average energy production of magnets will serve ; as to indicate the quality of a magnet system design for microwave tubes, the efficiency of magnetic energy utilization will be a very good criterion
由此得出結論,在非線性磁場計算中:採用迭代法的情況下,在各迭代循環之間進行磁導率修正時,一個欠鬆弛迭代過程是必需的;對永磁體中的等效電流修正時可以不作欠鬆弛迭代;在純鐵的磁化曲線上指定某一個固定的磁感應強度為磁飽和值,會使得插值求出的磁導率在該磁飽和值附近有一突變,這一突變對計算結果中磁場分佈變化的光滑性稍有影響。在微波管磁系統設計中,由於微波管磁路比較復雜,作者認為磁體的工作點並不能很好地反映磁體的工作狀態,而採用平均磁能積為衡量磁體工作狀態的標準更加符合微波管磁系統的實際情況;要表示磁系統設計好壞的程度,則用磁能利用的效率為標準更好。The formulation for the flow model is given using the finite element / control volume ( fe / cv ) technique based on darcy ' s law of creeping flow through a porous media. the heat transfer model is based on the two - dimensional, transient heat conduction equation, including heat generation. the cure kinetics model is based on kamal ' s model, and the degree of the resin cure as a function of temperature and time
