摘　　要：以某新型石油压裂输砂车大型砂罐为研究对象,通过建立U型砂罐三维有限元模型,分别对砂罐结构进行静态强度和动态振动特性计算。通过分析砂罐弯曲应力分布特点,发现了砂罐结构的强度薄弱点,并提出增强措施。计算出砂罐多阶振动模态特性,并对道路和发动机等外部振动源对罐体振动特性的影响进行详细分析。结果表明,罐体具有良好的抗外部激振特性。提出的研究方法对大型输砂车设计具有较好的指导意义。A new kind of large tank of U type for sand vehicle used in hydraulic fracture is studied in this paper. A three-dimensional finite element model of the sand tank is established firstly,then the characteristics of the tank such as static strength and vibrating modal are studied. The strength weak point is found based on the bending stress distribution characteristics analysis,and the improving measures is put forward. Not only the vibrating modal characteristics of the tank is obtained in detail,but also the effect of external vibrating source such as road and engine on the tank are also analyzed. The comparison results show that the tank has fine characteristics of anti-external excitation. The research method in this paper has directive value for developing large sand vehicle.
