  1. 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。
  2. This paper analyzed the criterion of the safety evacuation, factors affected on safety evacuation, calculating method of evacuation time and the smoke layer falling time, typically introduced the several calculation method that i had know, such as the japan three steps calculation method based on experience ( awareness time, travel time, queue time ), two computer modeling calculation method such as simulex and exodus and a spatial grid computer model of hongkong. and it also analyzed and certificated the application scope and difference between the computer modeling calculation methods and japan method with the practical project. all these are aimed to provided preference for performance - based design method and design of computer program for modeling evacuation of people, and advanced the steps of performance - based fire protection design method in our country

    本文對安全疏散的標準、影響安全疏散的因素、疏散時間和影響疏散的煙層下降時間的計算等方面進行分析,重點介紹了作者所掌握的疏散時間的幾種計算方法,日本的三步驟疏散時間經驗公式計算方法(察覺時間、步行時間、排隊等待時間) 、以及兩種計算機疏散計算模型simulex和exodus 、香港的空間網格計算機模型的計算方法等,並結合實際工程來分析驗證疏散計算機軟體模擬和日本經驗公式法之間的不同與適用性,並對疏散計算中的重要參數,人員密度和疏散人數的確定進行介紹,旨在為我國的性能化疏散設計與疏散模擬的計算機軟體的編制提供參考,同時促進我國性能化防火設計的進程。
