摘　　要：针对建立基于梁单元的客车结构模型的需要,提出了一种车窗玻璃参数化串联刚度模型。以客车车身侧围上部某典型局部为研究对象,对壳-体模型的准确性进行了试验验证;将壳-体模型的应力计算值作为目标应力值,运用参数设计的思想获得串联刚度模型的最优等效弹性模量;改变单元尺寸大小,获得串联刚度模型在不同单元尺寸下的最优等效弹性模量,建立单元尺寸-最优等效弹性模量关系曲线并确定曲线的函数表达式。最后,将两种单元尺寸的模型代入整车进行对比分析,结果证明了参数化串联刚度模型的有效性。To meet the requirements of the fast model of bus body structure based on beam elements,a parameterization series-stiffness model is proposed.Taking a typical part of the bus body side as the research object,the accuracy of the shell-solid model is verified be tests.Taking the calculated stress of the shell-solid model as the target stress,the optimum equivalent elastic modulus of the seriesstiffness model is obtained by parameter design method.Changing the element size to obtain different optimum equivalent elastic moduli of the series-stiffness model,the relationship curve of element size and the optimum equivalent elastic modulus is established,and the function expression of the curve is determined.Two series-stiffness models of different element sizes are introduced into the whole vehicle model to conduct analysis and comparison.The results demonstrate the feasibility of the proposed parameterization series-stiffness model.
