Abstract

It has a positive impact on the machining accuracy to predict precisely the thermal error caused by the temperature change for the high-speed spindle-bearing system. In this paper, the dual reciprocity method (DRM) based on compactly supported radial basis functions (CSRBFs) and the line integration boundary element method (LIM-BEM) are presented for the thermal-deformation coupling calculation. The essential idea of this method is building the thermal-deformation coupling model only by the boundary information and obtaining results by line integrals. In this process, the boundary element model discretized by the discontinuous iso-parametric quadratic boundary element is established. Then, the transient temperature is calculated by the CSRBFs-DRM, and the thermo-elastic deformation is done by the LIM-BEM, under the exact calculation of the heat generation and the thermal contact resistance. To validate the effectiveness, thermal-deformation coupling experiments are conducted. The proposed method is compared with experimental data and the finite element method. The result shows that the proposed model is more appropriate for the thermal-deformation coupling calculation for the satisfactory universality and accuracy.

高速主轴-轴承系统热变形耦合计算的新方法

准确预测高速主轴-轴承系统温度变化引起的热误差对加工精度有积极的影响。本文提出了基于紧支撑径向基函数(csrbf)的对偶互易法和线积分边界元法(LIM-BEM)进行热变形耦合计算。该方法的核心思想是仅根据边界信息建立热-变形耦合模型，并通过线积分得到结果。在此过程中，建立了用不连续等参数二次边界元离散化的边界元模型。然后，利用csrbf - drm计算瞬态温度，利用LIM-BEM计算热弹性变形，精确计算出热生成和接触热阻。为了验证该方法的有效性，进行了热变形耦合实验。将该方法与实验数据和有限元方法进行了比较。结果表明，该模型具有良好的通用性和精度，更适合于热变形耦合计算。
