Keywords: high speed train, SiPESC, optimization.

The newly developed software SiPESC was used to optimize the key components in the design of a high speed train. By the use of the SiPESC flow chart, the optimization can be executed automatically with consideration of the local and the whole models of the high speed train. The computational results show that the SiPESC software is very efficient for the controlling of the optimization process for the local model in a high speed train. The results obtained can be summarised as follows:
  1. By use of the SiPESC software, the optimization process can be controlled and managed by the flow chart.
  2. The function of each node in this flow chart can be deleted or modified according to the users. The function between two nodes should be defined to describe what can be done between the two nodes. Five selections including: function started; function ended; function stopped; procedure failed; and procedure error can be available between two nodes in the SiPESC flowchart.
  3. The volume of the local model for the train window can be decreased by 56.1% with 4.3% increase of the maximum von Mises stress.
