对某坦克工程车在起吊、挖掘工况下进行了受力分析，从机械系统的观点出发，应用机械结合技术，以解析的方法求解出车体的载荷条件和边界约束条件，建立了车体的有限元分析数学模型。采用三维空间板壳单元对车体在起吊、挖掘两工况下，不同工位时进行结构静特性的有限元计算，并对计算结果进行了分析，从静态角度对车体设计提出了结构修改建议。
The mechanical analysis of a tank construction vehicle under the conditions of hoisting and excavating is carried out. From the viewpoint of the mechanical system, the mechanical coupling technology is used to solve the load conditions and boundary constraints of the vehicle body by analytic method. Finite element analysis mathematical model. The three-dimensional space plate element is used to calculate the static characteristics of the structure under the condition of lifting and digging and the different working positions. The calculation results are also analyzed, and the structural modification is proposed from the static point of view Suggest.
