Short summary
Helicopters are easy to hit by hard objects during operation, harming pilots. So, we want to provide some technical references for the safe operation of helicopters. What are the factors that affect the safety? Then we analyze how to control this factor through simulation and specific experiments and observe the vibration of the equipment. Finally, results show that the stability of the equipment can be enhanced by designing a certain device to adjust the influencing factors.
