摘　　要：用静力学平衡方程无法确定全部约束反力和内力的结构就称为超静定结构。在机车设计中恰当地运用超静定结构可以增大结构的刚度,改善结构中的应力分布,降低结构应力,从而提高结构强度和抗振性能。The structure of which the all constrained forces and internal forces can not be deternined by static equilibrum equations is known as statically indeterminate structure.The proper use of the statically indeterminate structure can increase the structural stiffness,improve the stress distribution in structure,reduce the structual stress,and so increase the structural strength and improve vibration ristance.

关 键 词：超静定结构 机车 结构设计 应用
