本文主要是利用實驗結果來驗證並找出有關圓筒型壓力殼之壓潰壓力估算公式,所用之實驗設備為國內自製之深海壓力模擬試驗艙,其工作壓力可達120MPa,相當於深度1200公尺時之水壓。
實驗部分分為兩大部分進行,分別為無缺陷和含缺陷圓筒型壓力殼之壓潰實驗。無缺陷圓筒型壓力殼部分主要是使用各種不同尺寸之圓筒來進行壓潰實驗,借由實驗所得之壓潰壓力值,來找出適合本實驗之理論公式。而含缺陷圓筒型壓力殼部分為利用缺陷尺寸改變所求得之壓潰壓力,找出何者變化參數為影響壓潰行為之主因。
最後,以無缺陷模型之壓潰理論基礎結合含缺陷模型之實驗數據,以預估出含缺陷模型之壓潰壓力。
In this paper, we will find and proof the formulas about the crushing pressure of cylindrical pressure vessel by using the result of experiment. The experimental equipment is the experimental cabin of deep-sea pressure simulation made in Taiwan. It can work in 120MPa which is respectably 1200 meters-deep.
The experiment is dividing into two parts which are crushing experiment of flawing and non-Flawing cylindrical pressure vessel. In the part of non-Flawing cylindrical pressure vessel, we will perform crushing experiment by using various sizes of cylinders. And we will find the formulas fitting for this experiment by getting the experimental values of crushing pressure. In the part of flawing cylindrical pressure vessel, we will use the crushing pressure values of various flaws to find the major factor effects the crush characteristics.
Finally, we can estimate the crushing pressure of flawing cylindrical pressure vessel by combining the crushing formulas of non-Flawing cylindrical pressure vessel with the experimental data of flawing cylindrical pressure vessel.
