| 摘 要： | 由模态试验获取轮胎自由悬置的模态参数，应用模态分析技术进行轮胎力学研究，用模态综合法实现轮胎自由悬置到固定支承的转化，从而从理论上给出轮胎固定支承时的模态参数。计算结果与试验结果基本吻合。

| Abstract: | Applying modal analysis technology to the study of tire's characteristics is presented in this paper. Modal parameters of freely-hung tire are obtained from modal testing. By using modal synthesis, modal parameters are transformed from freely-hung state to supported one. The results of computation agree well with that of experiment. |
