【摘要】 由于轴的几何形状及支承方式的复杂性,转轴临界转速计算中的许多问题,是困难的问题。因此,设计人员只好采用近似解法,有限元法为求解这类问题提供一个比较好的,十分有效的方法。本文介绍座标镗床及车床主轴的计算结果,比较理论计算与实验测定表明,这一计计方法能适用于工程应用。更多还原

【Abstract】 Because of the complexities in geometric forms of the axle and the supporting Patterns, most of the calculations of the critical speed of turning axle are difficult. As a result, the designer must resort to approximate solutions. The finite element technique offers a relatively new and highly useful method for solving this problem.This paper presents the calculated results for the spindls of jig boring machine and turning lathe. Comparison of the theoretical calculations and experimental measurements shows that such calculation can be used in engineering applications.更多还原
