Lightweight Study On Heavy Truck Driving Axle

In recent years, in order to response to the call of national energy conservation and emissions reduction and environmental protection, the concept of the automotive light-weighting is frequently mentioned. More and more scholars have taken part in research on the lightweight technology while some achievements have already been made. Components need to meet various requirements during use process, which can be satisfied by coupling of multidisciplinary knowledge. There are some similarities on some common problems in the process of lightweight design, but the method varies depending on the difference among components. Heavy truck driving axle as one of the great quality components, its light-weight has greater significance of lower quality of vehicle, although many scholars have done corresponding lightweight researches, most of them stay in the level of single-constructive optimization of individual discipline, which will leads to chaos in the process of optimization, that is, only one use condition can be satisfied while others are being ignored. Focused on the above problems, studies which have been done in the paper are shown as follows:(1) Established the parameterized model of axle minimum support assembly for the axle actual working condition. On the premise of ensure the accuracy and improved the a. The theoretical calculation of the model has been done and proved the model need optimized design.(2) Established a rigid-flexible coupling dynamic simulation model of drive axle assembly. Get drive axle out of ADAMS’ dynamic response, access to a key position in the construction of dangerous points.(3) Study based on the approximate model of the multidisciplinary coupling drive axle assembly light weighting design method, to reduce the quality of the drive axle, and the optimized model validation.
