Abstract：

First,the application status and the analytical methods of tube hydro-forming technology were introduced,and then the friction mechanism between tube blank and mold was analysed.Based on the numerical analysis and experimental study,the influence of lubricating condition on the tube hydro-forming process parameters,such as axial feeding,thickness distribution of automobile instrument panel beam,was discussed.Finally,the results provide the theoretical references on the determination of feeding amount,selection of lubricating schemes and molds design during actual manufacture.
