“…However, lumped parameter method can hardly solve the problems of high nonlinear gearbox system because of its excessively simplified model. In this case, the finite element method [7][8] has been widely used in tackling the problems of vibration related to gear system. Additionally, experimental method [9][10] based on vibration detection is also a very important way to study the vibration of gear system, which can provide the support for vibration simulation.…”

Abstract. The vibration characteristics of gear system have a significant influence on mechanical capacity and durable life of vertical mill reducer. In order to improve the performance of reducer, this paper present the research on inherent characteristic and dynamic response of vertical mill reducer. First of all, the finite element model coupled gear-rotor-bearing-housing of reducer is established including internal dynamic excitation. Then, the natural frequencies and natural modes are worked out by mode analysis, which indicates resonance phenomenon will not occur in reducer system. Finally, the vibration displacement, velocity and acceleration of the reducer are obtained through dynamic response analysis, which illustrates the structure vibration energy mainly concentrates in the engage frequencies and their multiples.

“…A more recent approach from Guan, Lim and Shepard [9] uses the same actuator design in simulation, however for both gears. In [10] Guan et al compare four different actuator designs including the approaches of [8] and [7]. Their conclusion is that [7] has the most effective design concept, because it shows the best vibration transmissibility from actuator to the housing and because it shows the lowest power ratings and, in contrast to the concepts in [8] and [9], it does not require slip rings.…”

Due to the growing importance of electro mobility, the requirements in terms of noise and vibration harshness for drive trains with gearboxes driven by electronically commutated motors are continually increasing. A dominant component of the airborne sound emitted by such drive trains is the gear meshing sound originating from dynamic transmission errors. These nondesirable dynamic transmission errors show frequency components at gear mesh frequency as well as in its harmonics. In application these harmonics cause non-desirable high frequency components in the airborne sound. This paper presents a multi-channel adaptive feed-forward controller that is based on the LMS algorithm where the controller uses the electronically commutated motor as actuator. The dynamic behavior has been studied in simulation with a permanentmagnet synchronous motor and a two-degree-of-freedom gear pair model with an angle-dependent spring stiffness, a viscous damper and a transmission error excitation. Results showed that the controller is able to decrease the dynamic transmission error at gear mesh frequency and three additional harmonics simultaneously. Within the scope of this work, experiments have been carried out on a hardware-in-the-loop test bench including a permanent magnet synchronous motor with two gear stages and a magnetic particle break as load. Measurements show a housing vibration reduction of 31 dB and an airborne sound reduction of 13 dB at first gear mesh frequency. At second gear mesh frequency the controller reduces the structure borne sound by 18 dB and airborne sound by 15 dB.
