Structural Analysis and Optimization of Electric Scraper Drive Axle Housing under Multi-Load

Abstract:

As for the retrofit design problem of the drive axle housing of an imported electric scraper, UG software is used to establish the finite-element model of the drive axle housing, and the model credibility is verified through the static strength bench test. This paper uses NX Nastran advanced simulation module for structural analysis of the axle housing, which, firstly, establishes in turn the models of each subcase under the action of each single load, then combines the cases into four typical kinds of dangerous cases under the multiple loads' action. The results show: the axle housing has enough stiffness and good dynamic performance, but the strength is not enough on emergency brake and the rough-road abrupt break. Based on the AltairHyperOpt method, the axle housing is optimized, and the results show: the stress amplitude is reduced by 12.65% in the most dangerous case of the rough-road abrupt break, which satisfies the strength requirement; the total weight of the axle housing is reduced by 13.14%, which realizes lightweight.
