摘要
自动变速器是一种集机电液控为一体的高精尖装置,对车辆的动力性能有重要的影响。在自动变速器正向研发过程中,设计阶段需要准确的载荷谱数据作为边界条件进行结构优化设计和计算,确定被设计部件的强度和可靠性。以某型号6×6轮式车辆的自动变速器为研究对象,根据制定的典型工况进行实车道路测试实验,对采集的载荷信号进行消除信号和异常值剔除处理,利用雨流计数法进行统计计数,然后进行载荷数据外推,最终编织成八级程序载荷谱。从而为今后自动变速器变速箱设计提供依据。
Automatic transmission is an advanced device integrating mechanical and electrical hydraulic control, which has a significant effect on the vehicle＇s power of performance. In the development of automatic transmission, the design phase requires accurate load spectrum data as the boundary conditions for structural optimization design and calculation,in order to determine the strength and reliability of the components to be designed.The passage researches the automatic transmission of a type of 6×6vehicle automatic transmission, it has a real vehicle road test according to typical designed condition. It eliminates the signals and outliers eliminating for the acquisition of load signals. It has a statistical counting for the acquisition of load signals by using rain-flow counting method. Then it makes a load data extrapolation and weaves into an 8 program load spectrum, therefore, it can provide a basis for the design of automatic transmission gearbox in the future.
