Project description
Esfahan has a population of 1.8 Million people and is the capital of Esfahan Province in Iran, located about 340 km south of Tehran.
For the new Metro line 1 Kraiburg Relastec supplied its product DAMTEC® MSS P for vibration isolation.
The challenge was that the track is in a tunnel which is close to the Pol-e Chādschu bridge. This bridge is a well known landmark in Esfahan.
The technical service of DAMTEC® supported the project from the start by providing
- Vibration-related, mechanical and acoustic measurements
- Solution development / design
- Calculation and simulation
- Effectiveness forecasts
