Abstract
To shorten the AT development cycle and verify the design solution beforehand, the simulation analysis based modular development methods, including the NVH design and lubricating system CFD analysis of AT, are utilized to develop a hydraulic valve body with AMESIM and develop an oil pump with FLUENT, and carry out safety reliable design of transmission system with an advanced multi-body dynamic analysis method to optimize key component structure and effectively improve the AT performance. Meanwhile, the application of simulation drive design technology, in which CAE integrated technology is regarded as a key one, can significantly shorten the development cycle of new products and quantify the empirical knowledge and test data in the past development with higher development efficiency. In addition, the application of CAE engineering analysis and prediction technology helps the engineers with simulation analysis and prediction; therefore the product performance and quality can be significantly improved before obtaining type approval and putting into production, thereby reducing design cost and test frequency, as well as shortening the time for products to be put on the market.
