AI Technical Summary

Problems solved by technology

[0004] At present, there are relatively few special equipment available for vibration level drop test at home and abroad, and there is no special equipment for vibration level drop of marine couplings and clutches; at this stage, the vibration level drop test is usually performed when the measured object is in the actual installation and use state. When the test is completed, and there are defects in the test that the excitation force is large and the frequency range is narrow, or the frequency range is wide and the excitation force is too small, so it cannot meet the needs of the design and trial production of marine coupling equipment.

[0005] Although there is a fatigue durability test bench for coupling equipment, it has a single function and is only suitable for fatigue performance tests of specified types of equipment, and its power is relatively small, which cannot meet the requirements of marine coupling equipment. needs
