文章提出的卸积木式主轴静特性分析计算模型保留了实际主轴系统多支承、变截面的静不定特性,计入了支承的支反力矩,不仅避免了常用主轴计算模型给分析计算带来的误差,提高了分析计算的精确性,而且通用性强。在计算方法上,作者采用线性变换避免了大量高价矩阵运算,使计算量和内存需要量大为减少,从而使主轴的静特性分析和优化设计得以在微机上实现,对传统的复合形优化方法作了改进,加快了收敛速度,节省了机时。图2幅、表3个。
The analysis and calculation model of the static characteristic of the unloaded wooden spindle retained by the article retains the static characteristics of the multi-bearing and the variable cross-section of the actual spindle system and takes into account the support reaction moment, which not only avoids the error caused by the analysis and calculation of the commonly used spindle calculation model , Improve the accuracy of analysis and calculation, and versatility. In the calculation method, the author uses a linear transformation to avoid a large number of expensive matrix operations, so that the amount of computation and memory requirements greatly reduced, so that the spindle static analysis and optimization of the design can be achieved on the computer, the traditional complex shape optimization method Made improvements, speed up the convergence rate, saving machine time.
