Gearbox Noise and Vibration Prediction and Control
This paper will review practical techniques and procedures employed to quiet gearboxes and transmission units. The author prefers solving the gear noise problem at the very source to introduce an enclosure as a means to reduce radiated noise, which seems to be easy but its effect on the sound pressure level is small. The gearbox noise problem solution is focused on the improvement of gear desig...
متن کاملExperimental Analyses of Vibration and Noise of Faulted Planetary Gearbox
ABSTRACT Epicyclic gear trains are widely used in various industrial sectors due to their advantages over fixed-axis gears, such as high torque capability, compact size, differential and planetary designs, ease of adjusting gear ratios and even directions of rotation. This research focuses on planetary gearbox whose degree of freedom is one. The geometry and dynamics of the planetary gear train...
متن کاملFourier Series Analysis of Epicyclic Gearbox Vibration
Epicyclic gears are used in many applications because they can achieve a large torque/speed ratio in a compact package. In most gearboxes, the estimated spectrum of the vibration signal is symmetric and centered at the meshing frequency. For epicyclic gears, the estimated spectrum is typically asymmetric and the dominant frequency component does not occur at the meshing frequency. This is an im...
متن کاملResearch on vibration and acoustic radiation of planetary gearbox housing
In this paper, an analysis model of planetary gearbox housing is constructed based on finite element method/boundary element method (FEM/BEM). Its vibration and acoustic radiation characteristics are investigated. Firstly, the finite element model is established using ABAQUS. The main factors affecting its dynamic characteristics are observed through modal analysis. Then impact of main structur...
متن کاملSpatial modelling of railway noise propagation
In recent decades, population growth and progress of technology have shaped large and compact urban settlements. Existence of huge transportation systems and developed urban infrastructures are among the most important properties of modern cities. In spite of prompt transit and facilitated daily activities, development of transportation systems causes many problems, including traffic, air and n...
