| Research Abstract |
This study was conducted to support and improve techniques of marine engineers. We expect to help them detect engine operation malfunctions earlier. Our experiment was conducted by changing settings of diesel engines including the blast pressure of fuel valves and valve clearance. Results of multivariate analyses using sound and vibration in experiment confirmed the information of setting items. Then we verified whether or not the maintenance support system was able to support engineers' sensory memory. We used two sets of setting items in the experiment: a standard setting and a non-standard setting. We made our examinees experience sound and vibration in each setting. Subsequently, they answered a questionnaire asking if they were able to distinguish one setting from another by sound and vibration. Results showed that they were able to judge correctly with around 90% probability. We found that the maintenance support system was able to support the engineers' sensory memory.
