Experimental active vibration control of gear mesh harmonics in a power recirculation gearbox system using a piezoelectric stack actuator

Abstract

An experimental study of an active shaft transverse vibration control system for suppressing gear mesh vibratory response due to transmission error excitation in a high power density gearbox is presented. The proposed active control concept employs a piezoelectric stack actuator to deliver the control force through a secondary bearing. A versatile test stand that includes a closed-loop, power recirculating, dual-gearbox set-up capable of high load transfer is specially designed for this work. The underlying controller for computing the actuation signal is based on a modified filtered-x LMS algorithm with a robust frequency estimation technique. In order to avoid the common out-of-band overshoot problem, an integrated adaptive linear enhancer is also applied. Both single mesh frequency and multi-harmonic control cases are examined to evaluate the performance of the active control system. Additionally, the impact of the adaptive linear enhancer order as well as the controller adaptation step size on active control performance is evaluated. The experiments performed show more than 10 dB reduction in housing vibrations at certain targeted mesh harmonics over a range of operating speeds.

A Comparative Study Based on Different Control Algorithms for Suppressing Multistage Gear Transmission System Vibrations

“…That means both of the magnitudes of rotational speed and load remain constant, and the MGTS works under steady state conditions. As discussed by Li et al [7], for the FGMF, it has been proved that the proposed control method did not perform well and can not achieve significant control at this frequency. Thus, the following study will mainly focus on the single target harmonic vibration control.…”

“…The results show the vibrations reduction up to about 20 dB at the first two mesh harmonics. Li et al [7][8][9] adopted the FxLMS control algorithm to actuate the PZT to produce the active control force for reducing the gearbox vibrations, and the simulation work successfully demonstrated the feasibility of applying the proposed control scheme to gear vibration problems. Based on a combination of feedback and repetitive control strategy, Pinte et al [10] applied a modular bearing using piezostacks to generate secondary forces for suppressing the noise and vibration of the rotation machinery.…”

“…There have been remedies proposed for this problem. For example, Li et al [12] use on-line identification of secondary path. But this solution introduces new problems: The computational requirements will increase.…”

Experimental study on active structural acoustic control of rotating machinery using rotating piezo-based inertial actuators

“…or isolating the transmission force to the surfaces [18][19][20][21][22][23][24][25]. In case forces are applied directly to the noise radiation surfaces, passive tuned mass dampers [7][8][9][10], inertial shakers [11][12][13], reactive actuators [14] or piezoelectric patches [15][16][17] are often employed to produce the control forces.…”

“…Pinte et al [20] and Stallaert et al [21] adopted a similar approach, but used two piezoelectric actuators instead, which are perpendicularly mounted onto one of the support bearing locations in order to limit the force transmitted from the shaft to the housing. Instead of placing the actuator in series with the original bearing, Guan et al [22] and Li et al [23] proposed to mount the control actuator in parallel, directly on the shaft via an additional bearing (active shaft transverse vibration control). In such a case, the system suspension stiffness is not influenced by the introduction of the actuator.…”
