Noise and vibration of vehicles is an important consideration for both performance efficiency and passenger comfort. Gear noise is a significant contributor to NVH of vehicles. Gear transmission error is recognised as the main source of gear drive vibration. This proposal involves the prediction and measurement of gear transmission error of a rear axle differential. A second important component is to investigate the effect of various vehicle parameters and operating conditions such as speed, load and power on the noise produced for a given TE. The successful outcomes will result in great economic benefit to Australia's automotive and manufacturing industry.

车辆的噪声和振动是影响车辆运行效率和乘坐舒适性的重要因素。齿轮噪声是车辆NVH的重要影响因素。齿轮传动误差被认为是齿轮传动振动的主要来源。该方案涉及后桥差速器齿轮传动误差的预测和测量。第二个重要组成部分是调查各种车辆参数和运行条件(如速度、负载和功率)对给定TE产生的噪声的影响。这一成功的成果将为澳大利亚的汽车和制造业带来巨大的经济效益。
