MULTIBODY-SYSTEM-SIMULATION OF LARGE MOVEABLE RAILWAY BRIDGES

In conjunction with a railway crossing over the Suez Canal, a double-span swing bridge has been built at El-Ferdan near Ismaelia, which provides alternate crossing for a single-track railway line with a gauge of 1435 mm or a two-lane road with a deck width of 9.2 metres. The entire bridge structure is based on two identical swing bridges. Each swing bridge has a weight of approximately 5000 tons and cantilever girders of 170 m and 150 m in length, whereby the longer of the two cantilever girders is swung across the canal. With spans of 150/340/150 metres, this bridge is the largest swing bridge in the world since the handing over to the Egyptian National Railway in winter 2001. In this paper the oscillational behaviour of the bridge were analysed for different load cases using simulation techniques. The entire bridge has been transferred to a planar 24-mass model. The parameters of the model were included in the finite-element-calculation (FE) taken from the structural analysis. Additionally the drive technology, the buffer and wind excitation were modelled. Thus by the use of a simulation in the time domain the open, locked position as well as the closing operation were analysed for different load cases. In particular the possibility of failure of drive components was an important investigation topic. For the covering abstract see ITRD E122683.
