Keywords:
Gear Rattle, Vehicle Noise, Drive Line, Backlash, Techniques to Reduce Gear RattleAbstract
Acoustic comfort is an important criterion for sales of automobile manufacturers. For many years, research efforts led to the reduction of acoustic levels. Consequently, noise sources that were previously masked emerge. Specifically, gear rattle noise due to impacts between teeth of unloaded gears is particularly audible at the low-speed regime of the engine. Gear rattling noise is one of the major problems facing the industry, and the car industry in particular because cars spend so much time idling under no load or very light loads.
Many researchers had given their contribution in the field of gear rattle its causes and effect. Driveline contains many components, thus it has multiple degrees of freedom. Therefore, review of past literature helps in understanding and resolving the complicated problem and will be helpful for future work. This paper is the study of researchers work on gear rattle phenomenon, and vehicle noise, causes, and effects of gear rattle, Experimental analysis and conclusion by researchers, various techniques to reduce gear rattle, simulation etc.
