摘　　要：载荷是决定轴承使用寿命的关键参数,针对工程应用中轴承实际载荷通常较难获取的问题,基于轴承载荷与接触点位移间的线性关系设计了一种轴承动载荷测试装置。通过静载荷标定得到不同轴承载荷下的力传感器示值,0.99的相关系数表明轴承载荷与力传感器示值呈高度线性相关,采用一元线性回归方法进行拟合,得到轴承载荷与力传感器示值的转化系数,进而通过轴承动载荷测试装置有效测试了振动激励环境下的轴承动载荷。Load is a key parameter that determines service life of bearings.Aimed at the problem that the actual load of bearings is often difficult to obtain in engineering applications,a dynamic load measuring device for bearings is designed based on linear relationship between bearing load and contact point displacement.The indications of force sensor under different bearing loads are obtained through static load calibration.The correlation coefficient of 0.99 indicates a highly linear correlation between bearing load and indications of force sensor.A simple linear regression method is used for fitting to obtain the conversion coefficient between bearing load and indications of force sensor.The dynamic load of bearings under vibration excitation environment is tested effectively using a dynamic load measuring device for bearings.
