摘要
介绍了子模型技术在机车车体强度计算中的应用方法,并从工程计算的角度针对大轴重车体设计给出了算例,讨论了在设计中应用子模型技术的要求和要点,并对近似子模型方法作了简单说明,指出在设计中应用子模型方法进行强度验证具有对硬件要求低,便于实施、快速、准确等优点。
This paper presents the method of applying submodel technique in locomotive body strength calculation,and an example is given from the point of view of engineering calculation for heavy axle-load locomotive body design.The requirements and main points of the design application of submodel technique are discussed,and the approximate submodel method has made a brief introduction.The paper points out that the sub-model in the design strength verification method has a low hardware requirements,easy to implement,fast and accurate.
