摘要：
The track template is a crucial part of the high-speed railway's track constructing, and the manufacture experiences are still lacked in China. In this paper, the two times drawing process scheme is based on FEA of Dynaform. The pre-forming is the key step of the whole process. The performing scheme was established by simulation and experiment. The pre-formation's experimental results and simulation results are well coincided. The max relative error of width reaches 1.22%, and the max relative error of length is less than 4.86%. The eligible parts were formed by the drawing process and pilot production has applied to engineering practice.
