There are three main problems for engineers specializing in propulsion train calculations, which include shaft alignment,whirling vibration, bending vibration, axial and torsional vibration calculations. The first problem is a lack of a singleshaft model to perform all types of shaft related calculations. Oftentimes separate software with different data models forshaft alignment and for each type of vibration is used. The second problem is inability to analyse different operatingstates of propulsion shafting in one click. The User is forced to manage and maintain many files to achieve a finalsolution. The third problem is a substantial disparity between modern knowledge in propulsion train domain andcapabilities of the software in use. The above-stated reasons provided a starting point for development of a multi-project,multi-state, FEM-based propulsion train calculation package which integrates all types of engineering applications in thesingle CAE package named ShaftDesigner and closes the gap between theory and practice.
