摘　　要：根据双节公交大巴铰接盘的工况,取其单元体,建立切向坐标系下的动力学平衡方程和变形协调方程;经线性变换后,确定了内力与应力、应变的平衡关系,从而得出应变与内力的关系式;并引入微变积分函数,得出应变与微变积分函数的力学平衡关系;给出了铰接盘在不同载荷下,塑性区数量不同时的微变积分函数的表达式和曲线图,供工程技术人员设计时参考。According to the working condition of the double joint bus hinged plate, take its unit, the dynamic equilibrium equation and deformation coordination equation in tangential coordinate system are established. After the meridian transformation, the equilibrium relationship between internal force and stress and strain is determined. Thus the relationship between strain and internal force is obtained.And the differential integral function is introduced, the mechanical equilibrium relationship between strain and micro variable integral function is obtained. The mechanical equilibrium relationship between strain and micro variable integral function is obtained, the mechanical equilibrium relationship between strain and micro variable integral function is obtained, the mechanical equilibrium relationship between strain and micro variable integral function is obtained.
