Abstract

Abstract : Traditional tool was difficult to achieve digitisation and precision in manufacturing high-speed train panels. Thus, multi-point tooling was proposed as a novel and flexible manufacturing equipment. In this paper, the principle and implementation of multi-point tooling were described, and the key techniques in stretching and trimming process were discussed. To verify the feasibility and manufacturing effects in application, typical high-speed train panels forming process was carried out with multi-point tooling and commercial finite-element software, respectively. Comparison and analysis of strain distribution, thinning rate in thickness and shape errors were made between simulation results and experimental results. The results show consistency and may provide instructive guidance on high-speed train panels manufacturing.
