Full title:	Application of thrusters in arctic waters - HyDynPro
Duration:	03/2012 - 12/2015
Contributors:	Dr.-Ing. Thomas Rosenlöcher (TU Dresden, IMM) Dipl.-Ing. Christian Bauer (TU Dresden, IMM)
Financing:	BMWI
Objective:	The aim is to develop a solution to prevent the damage to bevel gear stages, bearings and seals occurring during the operation of thrusters by determining the real loads under extreme operating conditions under the consideration of dynamic influences and driving in icy waters.
Approach:	Overall dynamic view of thruster through detailed representation of input and output loads, supporting structure of the thruster and all drivetrain components in a multi-body elastic model Investigation of the transmission behaviour of bevel gear stages and development of a force model for the application in multi-body system models Experimental analysis of the damage mechanisms of bevel gears on the bevel gear test bench of the IMM
Results:	Development of a large propeller load model for the use in flexible multi-body simulation models Development of a detailed contact model of bevel gears for the use in multi-body simulation Determination of hydrodynamic effects and load cases leading to overload Comparison of different calculation methods for the determination of tooth flank fracture safety and experimental investigation Determination of fundamental influences that favour tooth flank fracture (TIFF)
