摘要
汽车行驶过程中燃油的晃动会对燃油箱产生持续的晃动冲击,在燃油箱油量不足的情况下,液面的自由晃动会影响供油的稳定性,特别是赛车比赛对速度和加速度的高追求,若供油不稳定,会影响赛车行驶,最终会影响比赛结果。基于VOF方法,运用Fluent软件对某款小型赛车两种结构不同的燃油箱,进行低油量下极限转向数值仿真,评价供油稳定性和燃油箱的设计,最终选择出结构更合理的燃油箱。
The car fuel sloshing in the process of a continuous shaking impact on the fuel tank, the fuel tank under the condition of insufficient oil, liquid sloshing of freedom will affect the stability of the oil supply, especially racing for high speed and acceleration of the pursuit, if the oil supply is not stable, will affect the car driving, will ultimately affect the result of the match.Based on the VOF method, using the Fluent software to a small fuel tank car, using two different kinds of analysis model, namely the standard turbulence model simulation, Laminar layers model simulation. To lower oil amount limit to numerical simulation of stability evaluation of oil and fuel tank design, also provide guidance for future fuel tank design improvement.
