中文摘要 封閉容器的自由液面晃動問題,在業界廣泛被討論,許多學者探討加工製造與燃料儲存問題時,皆會考慮到自由液面的晃動。自由液面晃動為一個複雜、非線性問題。本文想模擬出行進容器內的液面運動模擬分析,因此我們需要對整個容器做一些適當的基本假設,進而模擬出水波表面發生的變化。運輸帶上運動的載體會因運動行進間不同的加減速運動、慣性力產生不同的液面噴濺情況。
本文使用數值計算,利用有限體積法去模擬行進容器的自由液面晃動。並且想要有效的去抑制表面的晃動,但大多數的抑制晃動的方法都需要使用到感應器,然而輸入修正法不需要感應器就能有效抑制液面的殘餘震動,因此本文使用四種不同的輸入修正法,比較容器在行進過程中和靜止後的表面振盪減少。接著更進一步利用容器液體的質心位置求出質心軌跡搖擺範圍,並且與兩壁面的液面最大值找出關聯性。試圖找出最小幅度的噴濺振幅,並找到最有效率的運輸過程。
英文摘要 The sloshing problem of the free surface of a closed container has been widely discussed in the industry. Many scholars consider the sloshing of the free surface when discussing the problems of manufacturing and fuel storage. Free surface sloshing is a complex and nonlinear problem. This article wants to simulate the simulation analysis of the liquid surface movement in the traveling container, so we need to make some appropriate basic assumptions about the entire container, and then simulate the changes in the surface of the water wave. The moving carrier on the conveyor belt will produce different liquid surface splashes due to different acceleration and deceleration motions and inertial forces during the movement.
This paper uses numerical calculations and finite volume method to simulate the sloshing of the free liquid surface of the traveling container. And want to effectively suppress the sloshing of the surface, but most methods of suppressing sloshing require the use of sensors, but the input shaping does not require a sensor to effectively suppress the residual vibration of the liquid surface, so this article uses four different input-shaping schemes compares the reduction of the surface oscillation of the container during travel and after it is stationary. Then further use the center of mass of the container liquid to find the swing range of the center of mass trajectory, and finally find the correlation with the maximum value of the liquid level on the two walls. Try to find the smallest splash amplitude and find the most efficient transportation process.
