The design philosophy of the new model Z-PELLER aimed at both high thrust (Bollard Pull) and lightweight. The high thrust requires a strengthened power transmission system that inevitably leads to an increasing in size. Practically, it may not be compatible with both two performances due to the trade-off relationship between them.
Although the FEM-based optimization for an individual part design to balance the conflicting requirement may be effective, currently, it is still insufficient to analyze a whole model assembled intricately since the undetermined boundary conditions and the appropriate numerical solution is hard to obtain yet. Thus, an adequacy method should be introduced to evaluate beyond the conventional conditions and the newly adopted consideration.
In this paper, we introduce the load test facility developed by NIIGATA and the result of the actual load test by using this equipment.
