During the temperature fields, the results indicate that the processing parameters such as the extrusion velocity, casting temperature, perform preheating temperature, die preheating temperature and so on are important for the temperature fields besides the dwell time. they are must be in concordance each other to the deforming zone is in the quasi - solid state, and the stable semi - solid extrusion is implemented. during the deforming fields, the hyperbolic sine thermo - rigid - viscoplastic fem model is selected according to the forming feature of the process, and the variations of the stress - strain fields are studied
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。In this paper, the numerical simulation problem of the liquid infiltration extrusion technology that includes high pressure infiltration, heat conduction, solidification and large deformation is solved successfully, which provides theoretic basis for the parameters optimization and the application of the process
本文成功地運用有限元分析軟體解決了集高壓浸滲、熱傳導、凝固和大變形為一體的液態浸滲擠壓工藝過程的數值模擬問題,為該工藝的參數優化和實際應用提供了理論依據。The liquid infiltration - extrusion technology, as a new forming method which includes the liquid forging and the solid extrusion, has been developed in recent years. the process in essence is that after liquid metal is infiltrated into the fiber perform under pressure, high pressure is directly applied to it so that the melted metal is to be crystallized and solidified under pressure, and then undergoes large plastic deformation at the liquid - solid state or the state just solidified
液態浸滲擠壓是近年來發展起來的一種融液態模鍛和固態擠壓為一體的新成形工藝,其工藝實質是使液態基體金屬在壓力下滲入纖維預制體中,發生壓力下結晶凝固,並在液-固態或剛凝固態經受大的擠壓塑性變形,一次成形出金屬基復合材料的型材類製件。Then the penalty finite element formula can be derived through galerkin weighted residual method. to test the model, the paper calculate a cantilever sample and a four point bending beam under near static load and sinusoidal load
針對浸泡在液體中的懸臂梁試件和四點彎曲試件,計算了在受躍階載荷和正弦載荷作用時的變形、流動以及流動電場分佈。分享友人
