基于MATLAB GUI的角接触球轴承接触疲劳寿命计算系统设计

滚动轴承是机器中广泛应用的零件之一,依靠滚动体和滚道间的滚动接触来支承转动零件,轴承的使用寿命是轴承质量的重要衡量指标。针对滚动轴承失效形式主要是疲劳点蚀,往往采用接触疲劳寿命来反映轴承寿命,它综合考虑了轴承材料、接触特性等因素,更符合实际工况。采用MATLAB GUI软件平台完成角接触球轴承接触疲劳寿命计算系统设计,该系统使用方便,只需输入相关参数,便可计算出接触疲劳寿命、最大接触载荷和最大接触应力等参数,结果可在系统界面显示或输出txt文件和excel表格。该系统大大缩短了轴承寿命计算周期,提高轴承设计效率和精度。通过多次工程设计验证,该系统高效可靠,为工程设计中其他复杂计算系统的开发提供了参考。

Design of Calculation System for Contact Fatigue Life of Angular Contact Ball Bearing Based on MATLAB GUI

Rolling bearing is one of the most widely used parts in machines. It relies on rolling contact between rolling elements and raceways to support rotating parts. The service life of bearings is an important indicator of bearing quality. As the failure form of rolling bearings is mainly fatigue pitting, contact fatigue life is often used to reflect bearing life. For its calculation, bearing material, contact characteristics and other factors are comprehensively considered, which is more in line with actual working condition. The MATLAB GUI software platform was used to complete the design of the contact fatigue life calculation system for angular contact ball bearings. The system was easy to use. By entering relevant parameters, the parameters such as contact fatigue life, maximum contact load and maximum contact stress could be calculated. Txt files and excel forms could be displayed on the system interface. Using this system, the calculation period of bearing life is greatly shortened, the efficiency and accuracy of bearing design are improved. After many engineering design verifications, the system is efficient and reliable, and has reference significance for the development of other complex computing systems in engineering design.
