高壓旋噴注漿技術具有適用范圍、適用地層較廣，施工方便，耐久性好，材料廣闊等特點；其加固地基機理主要是通過流動壓、噴射流的脈動負荷、水塊的沖擊力、空穴現象、水楔效應、擠壓力、氣流攪動等效應形成水泥固結體與樁間土的復合地基，從而提高地基承載力，減少沉降變形。 -
In different in terne die travel, the metal flow characterize in warm extrusion forming processes and the affection for the flow of metal stage which made by the difference between the blank bottom altitude and the axial direction limiting size in warm extrusion forming technique have been analysed we have gotten the equivalent strain field and the velocity field and other field variable that the blank in different in terne die travel and the die travel - load curve. at the same time, we have analyzed the contributing factor for the oil pump stator forming process optimized and achieve thereasonable die parameter for the war m extrusion forming finally, the optimized technics parameters were used into pilot production, then the qualified oil pump stator forging were produced, the analog results were compared with those of pilot production
論文具體分析研究了不同成形工藝過程中金屬流動的特點，並對不同凸模行程下溫擠成形過程中的金屬流動特點、坯料連皮厚度（底部高度）與溫擠壓成形工藝中的軸向界限尺寸的差值對金屬變形階段的影響進行了分析，獲得了坯料在不同凸模行程下的等效應變場、速度場等場變量及凸模行程-載荷曲線，同時對油泵定子成形過程的影響因素等進行了分析，優化並獲得了合理的溫擠成形工藝及模具參數。最後，利用模擬優化獲得的各項工藝參數進行生產實驗，得到實際生產出的合格油泵定子件，並將模擬結果與生產實驗結果進行比較。 -
