| Abstract:The test run intermediate shaft of WARTSILA W7X35 diesel engine met the problem that the torsional vibration was beyond the scope of international classification society and WARTSILA limits，and had the shortcomings of difficult installation and low economic efficiency. Thus optimal design of the intermediate shaft was carried out. It was verified by bench test that the optimized intermediate shaft could meet the torsional vibration requirements of the diesel engine, and boasted large improvement on reliability, economic efficiency and operability. |
