Abstract

The invention relates to a car strength and fatigue early-warning method and system. The car strength and fatigue early-warning system comprises a spindle nose load signal interface unit, a signal conversion unit, a storage unit, an initialization unit, a counting unit and an early-warning unit. The car strength and fatigue early-warning method comprises the steps that a six-component sensor is used for testing a car spindle nose load signal in real time, an early-warning system is used for converting the car spindle nose load signal into a spindle nose load force signal F, the F is compared with a strength limit load F0, a low-cycle fatigue load F1 and a high-cycle fatigue load F2, early-warning information can be sent out when the frequency n0 of the situation that the F is larger than the F0 is larger than or equal to 1 and the frequency n1 of the situation that the F is larger than the F1 is larger than or equal to the low-cycle fatigue cycle frequency N1 or the frequency n2 of the situation that the F is larger than the F2 is larger than or equal to a high-cycle fatigue cycle frequency N2, and a user is prompted to carry out maintenance. The car strength and fatigue early-warning system and method are applicable to car overall strength and fatigue forecasting, the user can monitor the car strength and fatigue in real time, the user can be prompted to carry out timely maintenance, and car fatigue damage caused by overlarge loads can be reduced.
