高强度钢板在油罐半挂车上的应用研究

The Application Study of High Strength Steel in Tank Semitrailer

油罐车内部晃动的液体与罐体结构的耦合振动引起对油罐半挂车的设计提出了更高的要求,不仅使其具有适应复杂工况的强度、刚度以及动力学特性,而且具有节能、环保以及高运载量的特点。因此,采用高强度钢板,对油罐半挂车进行轻量化设计变得越来越迫切。为了获得轻量化设计的油罐车的特性。建立了该油罐半挂车的静力学和流固耦合系统有限元模型,通过对实际模型进行静力学分析和流固耦合模态分析,获得了匀速行驶、紧急制动、转弯和加速上坡四种典型工况下油罐半挂车的应力和位移分布情况以及空载、50%贮液量和90%贮液量等三种工况下油罐车的模态响应,为高强度钢板在油罐半挂车上的应用及结构优化设计提供了理论基础。

Higher request to the design of the oil tank semi-trailer put forward by tankers coupling vibration of sloshing liquid and tank structure.Not only adjusts to the structure strength,stiffness and dynamic characteristics in complex conditions,but also have traits of energy conservation,environmental protection and higher load capacity.Therefore,it is urgent to use the strength equivalent design theory to do the lightweight design of the tank trailers.In order to obtain tank semi-trailer characteristics of lightweight design,the finite element model system is established about tank semi-trailer based on the statics and fluid-solid coupling.The stress and displacement distribution is obtained about uniform driving,turning,accelerate and uphill using the actual model.The modal response of the tank semi-trailer is also acquired in the condition of the 0%,50% and 90% of the liquid.The theoretical basis is provided for the application of high strength steel in tank semi-trailer and structure optimization of it.
