[0002] Bearing is an important part in modern mechanical equipment, its main function is to support the mechanical rotating body, reduce the friction coefficient in the movement process, and ensure the rotation accuracy. The bearing adjustment process parameters are closely related to the service performance of the bearing. By optimizing the adjustment process parameters of the bearing, the service performance of the bearing can be improved.

[0003] At present, many bearings in China are assembled on the rotor system by the experience of the assembly workers, the quality parameters of the rolling bearings qualified in the actual use have large performance differences, the influence of the adjustment process on the service performance of the bearing and the rotor system is not considered, and the optimization of the process parameters in the actual adjustment depends on experience.

[0004] After searching, it is found that there is no method for improving the service performance of the bearing by optimizing the adjustment process parameters of the bearing. Therefore, it is necessary to develop a rolling bearing adjustment process parameter optimization method to improve the service performance of the bearing. SUMMARY

[0005] Based on this, in order to improve the service performance of the bearing, the present application provides a rolling bearing adjustment process parameter optimization method, and the specific technical scheme is as follows:

[0006] A rolling bearing adjustment process parameter optimization method, comprising the following steps:

[0007] S1, a function relationship formula is constructed with the adjustment process parameters as the independent variable and the service performance index as the dependent variable;

[0008] S2, a multi-parameter multi-objective optimization process is carried out with the adjustment process parameters as the optimization parameters and the service performance as the optimization target;

[0009] S3, the optimization result is obtained, and the optimization result is used as the optimized adjustment process parameter.

[0010] The rolling bearing adjustment process parameter optimization method can automatically obtain the optimized adjustment process parameter and improve the service performance of the rolling bearing by constructing the function relationship formula with the adjustment process parameters as the independent variable and the service performance index as the dependent variable, and carrying out the multi-parameter multi-objective optimization process with the adjustment process parameters as the optimization parameters and the service performance as the optimization target.

[0011] Further, the adjustment process parameters are adjustment load, adjustment phase or connection load.

[0012] Furthermore, the service performance index is a service performance parameter of the bearing body or a service performance parameter of the bearing-rotor system.

[0013] Furthermore, the bearing service performance is the maximum contact stress of the bearing or the friction torque of the bearing.

[0014] Furthermore, the service performance of the bearing-rotor system is the critical speed of the rotor system, the unbalanced response of the rotor system or the dynamic stability of the rotor system.

[0015] Furthermore, a computer-readable storage medium stores a computer program, which implements the rolling bearing assembly process parameter optimization method when the computer program is executed by a processor. BRIEF DESCRIPTION OF THE DRAWINGS
