【摘要】 将轮胎视为支承在具有一定切向刚度和径向刚度的弹性基础上的二维弹性体，采用移动的拉格朗日坐标，建立稳态形式的控制场方程及边界条件。通过半解析法对轮胎的临界转达作了数值计算，并与有限元结果作了比较。更多还原

【Abstract】 The tire is modeled as a 2-D elastic body,which is supported on a elasticfundation with radial and tangential rigidities. By use of moving Langrange system,thesteady state type governing equations and boundary conditions are established.The numerical computation of critical speed is performed by the semi- analysis method,and the results arecompared with those obtained by the finit element analysis.更多还原
