摘要
为深入完善风电锁紧盘设计理论,首先基于厚壁圆筒受均布载荷作用下的位移表达式,推导了多层圆筒过盈配合各配合面接触压力和过盈量的计算公式;根据所得计算公式设计的某型号风电锁紧盘尺寸,采用ABAQUS软件建立了二维轴对称模型并模拟了其动态过盈装配;比较了两种方法的计算结果,并分析了两者误差产生的原因。结果表明,该文给出的解析算法与有限元数值方法所得结果吻合较好,可以为风电锁紧盘设计提供可靠的理论指导。
In order to provide theoretical basis for the design of wind turbine＇s shrink disk, the calculating formula of contact pressure and magnitude of interference for interference fit of multi-layer cylinder has been deduced based on the displacement expression of thick-walled cylinder under uniform pressure. Two-dimensional axisymmetric model was established by using the finite element software ABAQUS with the dimensions of some type wind turbine＇s shrink disk, which was designed based on the calculating formula above, and the dynamically- simulated interference assembly was carried out. The results of contact pressure on the mating surfaces by both methods were discussed, and the errors between the two methods were analyzed. The results show that the results by analytical formulas agree well with those by finite optimization design of wind turbine＇s shrink disk_ element method and can provide theoretical guidance to the
