Analysis of Excitation Behavior of Two-Stage Gearbox Based Upon Validated Simulation Model

摘要

In order to reduce costs for development and production, the objective in gearbox development and design is to predict running and noise behavior of a gearbox without manufacturing a prototype and running expensive experimental investigations. To achieve this objective, powerful simulation models have to be set up in a first step. Afterwards, those models have to be qualified and compared to experimental investigations. During the investigation procedure of gearboxes, there are two possibilities to evaluate the running and noise behavior: quasi-static and dynamic investigations. In times of engine downsizing, e-mobility and lightweight design, the dynamic excitation behavior is becoming increasingly important. Opposed to the quasi-static excitation, the dynamic excitation behavior of the gearbox regards increased load at resonance points caused by the dynamic behavior of the complete drive train.
