Application of Kriging Surrogate Model in Performance Parameters Optimization of Excavator Cab Shock Absorbers

Abstract:

The surrogate model has been extensively applied in engineering optimization design recently. Based on surrogate model, the complicated functional relationships between variables and responses can be precisely described. In this paper, the Kriging surrogate model are adopted to simulate the relationships between the sound pressure level (SPL) peaks at the drivers right ear (DRE) and the performance parameters of excavator cab shock absorbers with the FEM model, followed by the optimization design been accomplished with algorithm NSGA-II. The results indicate that the SPL peaks and the overall SPL can both be decreased through optimizing the performance parameters with Kriging surrogate model.
