| Abstract: | With MSC.Dytran and MSC.Patran software of MSC.Software Company, this paper estabhshes a finite-element model of D high speed train passing through tunnels, with the fluid-solid coupling algorithm of MSC. Dytran, it conducts 3-dimensional numerical simulation of the shock wave response when high speed train entering tunnels, and by comparing with testing results, it concludes that dynamic analysis results with MSC. Dytran are basically in accordance with actual situation. |
