Failure Analysis in Hydraulic System of the Polar Expedition Buoy which is based on Virtual Prototype

摘要

Introduced the particularity circumstances of polar exploration buoy in contrast to normal buoy, raised the important academic value and practical meaning of the research of failure of the polar ocean observing buoys. This paper is based on, a pair of gear pieces in hydraulic system of polar buoy, and made the virtual prototype simulation experiment on the fault gear pieces. By comparing of the normal meshing with broken teeth meshing which drew the presence of failures, and then analysis the CM acceleration both in time-domain and frequency-domain of fault gear in different rotating speeds, which verify the correctness of the simulation.
