Frame Optimization Design And Steering Stability Analysis Of Oil Tank Truck

China is a big country in energy exploitation and export,in which oil resources occupy a high position in China’s energy types.Therefore,it is particularly important to ensure the exploitation and safe transportation of oil resources.The transportation of oil resources mainly includes pipeline transportation,railway transportation,highway transportation and so on,among which the highway transportation is the most common,that is,the use of oil tank trucks for the transportation of oil resources.The oil tank truck is a heavy-duty truck with the characteristics of long body,high center of mass and large inertia.The liquid sloshing in the tank will also occur during transportation.Especially when the oil tank truck turns,the liquid in the tank will have a large transient impact on the inner wall of the tank due to the sloshing,which may become the inducement of the rollover accident of the oil tank truck.Therefore,it has certain theoretical significance and engineering value to study the dynamic characteristics of liquid sloshing in the tank during the steering process of the tank truck and the impact of liquid sloshing in the tank on the driving stability of the tank truck.With the development of automobile manufacturing industry,China has become the largest country in the production and export of automobiles in the world,followed by greenhouse effect,environmental protection,energy conservation and emission reduction and other related issues.Therefore,while studying the stability of oil tank truck,we also need to study its optimization related problems,including material selection of oil tank truck,size optimization of relevant parts and so on.In this paper,the above problems will be analyzed and studied by using relevant simulation software.The main work contents are as follows:Firstly,consult the relevant literature at home and abroad,including the optimization design and stability analysis of tank cars,learn advanced ideas and research methods,and find the shortcomings of others’ research,so as to form their own paper system.Then,according to the real vehicle drawings,the three-dimensional modeling of the tank part of the oil tank truck is carried out by using SolidWorks software to ensure that the components of the oil tank model are similar to the real vehicle model,and the three-dimensional model of the oil tank is modal analyzed.Then,the material of each part of the oil tank model is selected,and the stress analysis under several different working conditions is carried out to illustrate the feasibility of the selected material from the perspective of statics.After completing the above work,the next optimization design and liquid sloshing simulation can be carried out.Next,the frame model is optimized,and the size is optimized by using the Optistruct optimization module in HyperWorks software.When the size optimization has the preliminary results,the similar modal analysis and force analysis in the above research are carried out on the optimized frame model to verify the feasibility of the optimization results,and the relevant parameters of the frame before and after optimization are compared to illustrate the effect of size optimization.Finally,the dynamic simulation of the impact of liquid cargo sloshing in the tank on the driving stability of the oil tank truck is carried out.The dynamic characteristics of liquid sloshing in the tank are simulated and calculated by FLUENT software.Taking different liquid filling ratio and lateral acceleration as variables,several groups of simulation calculations under different working conditions are carried out,and then the data results are sorted out to illustrate the influence of liquid filling ratio and lateral acceleration on the driving stability of oil tank truck.Figure[38]table[11]reference[85]...
