Abstract
The invention relates to a method for processing nonlinear stiffness data of suspension systems of power assemblies of automobiles. The method includes steps of 1), enabling a data input module to input suspension static stiffness data, suspension static force data of the power assemblies, maximum displacement data of compression directions under extreme working conditions and maximum displacement data of stretching directions under the extreme working conditions into a data processing module; 2), enabling the data processing module to determine static points; 3), enabling the data processing module to adjust correction parameters of the compression directions and correction parameters of the stretching directions until nonlinear stiffness curve data meeting limit requirements of the extreme working conditions are obtained; 4), enabling the data processing module to output expressions of nonlinear stiffness curves to a data output module; 5), utilizing data of the expressions of the nonlinear stiffness curves for designing the suspension systems of the power assemblies of the automobiles by the aid of the data output module. Compared with the prior art, the method has the advantages of capability of effectively reducing computation workload, simplicity and convenience in operation, and the like.
