| 摘 要： | 给出了考虑温度和转速影响的涡轮叶尖径向间隙的分析计算方法。用ＡＮＳＹＳ有限元软件计算出涡轮叶径向间隙的时间历程变化趋势，其中叶盘径向位移主要考虑温度和转速的影响，机匣径向位移主要考虑温度的影响。该分析计算方法为进一步开展涡轮叶尖径向间隙主动控制的研究奠定一定的基础。

| Abstract: | The calculation method for radial clearance of turbine blade tip considering the effect of temperature and rotational speed is developed in this paper. The transient change of turbine blade tip clearance during the whole flight is computed by means of ANSYS finite element program. To calculate radial displacement the influence of temperature and rotational speed on the turbine and the effect of temperature on the case are considered. The methodology presented in this paper can lay some foundations for further study to control radial clearance of turbine blade tip. |
