Automated Mechanical Transmission (AMT) designed on the ground of Manual Transmission and dry clutch, is able to realize automotive starting and shifting of the vehicle by electro-hydraulic actuator that is controlled by Transmission Control Unit (TCU).

电控机械式自动变速器(AMT)是在原有固定轴式手动变速器和干式离合器的基础上应用自动变速理论和先进的电子控制技术，通过电子控制单元控制电、液执行机构实现车辆动力系统的自动操纵。

But because of lack of understanding of fatigue design and some basic data such as Road Load Data and material S-N curves, many domestic manual transmission designers don’t apply fatigue design in their product.

但目前,国内各汽车变速器厂家在变速器的设计开发中,应用疲劳设计方法的还不多。 这是对疲劳设计方法的认识不够和缺乏载荷谱、S-N曲线等基础数据等原因造成的。
