| Abstract: | There is an urgent demand on high performance, complex geometry, integral structure, and thin-walled components with the development of new generation aircraft, high-speed trains and new-energy vehicles toward the directions of large size, light mass and high performance with longer service life and higher reliability. The major manufacturing difficulties are the interdependent effects of poor formability of materials, complicated geometrical profiles as well as the demand on high performance after these components are fabricated. However, it is a huge challenge to fabricate these components by conventional forming technologies for the forming windows beyond the limits of processes. In order to solve the above technological problems, several new techniques are developed and introduced for the forming of these kinds of structures in this paper, including low pressure hydro-pressing of tubular components with irregular cross-sections, controllable multi-directional sheet hydroforming of thin-walled components with deep cavities and curved surfaces, and hot medium pressure forming of thin-walled components with hard-to-deform materials. |
