【摘要】 介绍了应变法监测柴油机滑动主轴承磨损状态的研究，计算了主轴承负荷、轴心轨迹和纵向 油膜力，实测了不同磨损状态主轴承的纵向应变，确定了主轴承磨损状态与纵向应变之间的关系 特征，为实现柴油机滑动主轴承磨损状态的在线监测奠定了技术基础．更多还原

【Abstract】 Wearing condition strain monitoring of main journal bearing in diesel engine is presented in this paper,The main journal bearing load,the 1ocus of the crankshaft center and the oil film pressure are calcu1ated,and the strain signals in vertical direction on the cover of the main journa1 bearing are mea- sured under different simulated wearing condition. The relations between the wearing conditions of the main journal bearing and the strain in vertical direction are established,which is useful to monitor the wearing condition of main journal bearing in diesel engine online.更多还原
