| Abstract | This paper describes a model-scale test program that was designed to simulate the type of impacts that occurred during the Bergy Bit Trials. The model tests were conducted as part of a validation study of the inertial measurement system called MOTAN. Various types of controlled impact tests were conducted, during which global impact forces on a model of the TERRY FOX were compared to those measured independently on the impact plate. Percent differences between the two measurement systems ranged from 6.3 to 12.1% for the sway and pitch forces, depending upon whether the impact was symmetrical or oblique. The surge force from MOTAN was about 20% less than the longitudinal force measured on the impact plate. Results showed that MOTAN is a viable means of measuring ice-induced global impact forces and, therefore, is feasible for measuring loads on ships, at full-scale, during icebreaking operations. |
