摘　　要：介绍了汽车油箱总成在汽车燃油系统中的重要作用,即汽车油箱总成不仅储存燃油,还能实现供油和输出燃油余量信息。当油箱内的燃油耗尽时,车辆会因供油不足而熄火。然而,在高速环道行驶时偶尔会遇到燃油耗尽前就出现供油不足的情况,主要是由于高速环道与地面形成较大夹角,加上车速的变化导致燃油耗尽前供油不足。为了解决这个问题,建立了一个分析模型,通过该模型可以预测车辆在高速环路上行驶时油箱内燃油分布情况和剩余里程。具体来说,通过建立受力分析模型,分析了固体在斜面上静止和运动时的受力情况,并将其应用到液体在斜坡上运动时的受力和分布情况分析中。最后,通过案例分析验证了该分析模型的准确性,并提出了在汽车设计阶段使用该模型进行油箱设计,可以提前发现低油位熄火风险并改进设计,从而提高汽车的安全性和可靠性。This article introduces the importance of the fuel tank assembly in vehicle fuel system,which not only stores fuel but also achieves fuel supply and output the remaining fuel volume.When the fuel in the tank runs out,the vehicle will shut down due to insufficient fuel supply.However,when driving on high-speed roads,the fuel may run out before the vehicle shuts down.This is mainly because the large angle between the high-speed road and the ground,and the change in speed can cause insufficient fuel delivery before the fuel runs out.To solve the problem,this article establishes an analytical model that can predict the fuel distribution and remaining mileage in the fuel tank of a vehicle while driving on a high-speed loop.Specifically,this article establishes a force analysis model to analyze the force situation of a solid at static and moving state on an inclined plane,and applies it to the analysis of the force and distribution of a liquid moving on a slope.Finally,this article verifies the accuracy of the analytical model through case analysis and using this model for fuel tank design during the vehicle design phase,which can detect the risk of vehicle shut down at low fuel levels in advance and improve the design,and improve the vehicle safety and reliability by making necessary design modifications.
