提出了多层过盈配合的理论模型，给出了径向过盈量与摩擦系数的关系式。以典型的三层过盈配合结构的风力涡轮机收缩盘为例，研制了专门的试验装置，对收缩盘的抗扭能力进行了测试。根据试验结果和理论模型，通过多项式拟合得到了径向过盈量和装配行程对摩擦系数的数学表达式，建立了摩擦系数的预测模型。应用摩擦系数预测模型，建立了缩径盘的三维有限元模型。通过扭矩能力的径向过盈量和装配行程的数学表达式，分析了主要尺寸参数和扭矩能力的规律。实验与仿真的最大相对误差为8.2%，表明了有限元仿真的可行性。研究结果对摩擦系数的预测和多层过盈配合的制造具有一定的指导意义。
This paper proposes the theoretical model of a multilayer interference fit and gives out the relational expression between radial interference and friction coefficient. Taking the typical wind turbine's shrink disk of a three-layer interference fit structure as an example, special experimental equipment is developed to test the torque capacity. Based on experimental results and the theoretical model, the mathematical expressions of radial interference and assembly stroke for friction coefficient are obtained by polynomial fitting, and the prediction model of friction coefficient is established. The three-dimensional finite element model of a shrink disk is constructed by applying the friction coefficient prediction model. With the mathematical expressions of radial interference and assembly stroke for the torque capacity, the rules of main dimension parameters and torque capacity are analyzed. The maximum relative error between experiment and simulation is 8.2%, which shows the feasibility of finite element simulation. The results of our study have certain guidance for the prediction of friction coefficient and the manufacture of the multilayer interference fit.
