Abstract

Abstract: In this study, the Fluent software is utilized to simulate the lateral impact force on a tank during liquid sloshing when the tank is subjected to turns under varying steering accelerations and filling rates. It is observed that at a steering acceleration of 0.5g, the overall force vector pointing in the lateral direction of the tank body significantly increases the likelihood of tipping. A clear trend arises when steering acceleration is held constant; as filling rates range from 0.6 to 0.85, lateral impact forces due to tank liquid sloshing progressively increase with rising filling rates, whereas a decrease in force occurs between filling rates of 0.85-0.9. This analysis reveals that tanker truck safety is relatively high during turning maneuvers when the filling rate is between 0.85 and 0.9 and the steering acceleration is in the range of 0.1-0.4g.

LNG运输过程中冲击动力学仿真研究

摘要:本研究利用Fluent软件模拟了在不同转向加速度和加注速率下罐体转弯时液体晃动对罐体的侧向冲击力。可以观察到，当转向加速度为0.5g时，指向罐体横向方向的总力矢量显著增加了倾覆的可能性。当转向加速度保持不变时，趋势明显;当填充率为0.6 ~ 0.85时，随着填充率的增加，由于罐内液体晃动引起的侧向冲击力逐渐增加，而在填充率为0.85 ~ 0.9之间，侧向冲击力则逐渐减小。分析表明，当加油率在0.85 ~ 0.9之间，转向加速度在0.1 ~ 0.4g之间时，油罐车转向机动的安全性较高。

期刊介绍： International Journal of Numerical Methods for Calculation and Design in Engineering (RIMNI) contributes to the spread of theoretical advances and practical applications of numerical methods in engineering and other applied sciences. RIMNI publishes articles written in Spanish, Portuguese and English. The scope of the journal includes mathematical and numerical models of engineering problems, development and application of numerical methods, advances in software, computer design innovations, educational aspects of numerical methods, etc. RIMNI is an essential source of information for scientifics and engineers in numerical methods theory and applications. RIMNI contributes to the interdisciplinar exchange and thus shortens the distance between theoretical developments and practical applications.
