| 中文摘要 | 利用有限元软件ANSYS中的接触单元模拟高温气冷堆主氦风机叶轮与转轴的过盈配合。通过调节接触单元实常数确定有限元初始过盈量,针对不同过盈量、不同的叶轮与轴间的摩擦系数和不同的叶轮转速,计算分析叶轮和转轴过盈面间接触压力分布。结果表明,沿圆周方向接触压力呈现周期性变化,接触压力随着过盈量增加线性递增;转速越高,配合面靠近轮盘侧压力越低,但靠近轮盖侧则越高。; In this paper, the contact elements in software ANSYS are used to simulate the interference fits for the impeller and the shaft in a high temperature reactor(HTR) primary helium circulator. Initial finite element magnitude of interference could be defined by adjusting these contact elements' real constants, The simulations have been carried for different magnitude of interference, different friction coefficients and different impeller rotational speeds, contact pressure distributions on the fitting surface under these parameters are given. The results show that contact pressure changes along the circumferential direction periodically and it increase with the increase of magnitude of interference linearly. The higher rotational speed of impeller is, the lower contact pressure is on fitting surface close to the hub side and higher contact pressure is close to the shroud. |
