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
