Abstract

The vibration analysis of a gearbox housing model is essential for the design of an electric vehicle but requires large computational costs. In this study, we applied a high-fidelity reduction technique to analyze the gearbox housing model for an efficient numerical analysis. Moreover, the rigid multi-point constraints (MPCs) were employed to establish a connection between the housing and the internal mechanical parts. A governing equation was established from the Lagrange multiplier-based formulation to unify the reduction process and the application of the rigid MPCs. Furthermore, the dynamic correction technique was applied to the unified reduction process to compensate for the reliability of the reduced model. Consequently, the reduction model had reduced computational costs and high accuracy. Thus, the proposed model that has connection points between the housing and the shaft can be used to reflect the effects of the other gear, shaft and bearing parts on the gearbox housing.
