摘要：
Premature wear, fatigue and other failures caused by non-linear vibration are one of the key problems of aerodynamic power transmission in spline coupling which maybe suffer from abnormal meshing effects due to misalignment between internal spline and external spline. A non-linear dynamic model of the misaligned spline coupling is established, which involves the calculation of dynamic meshing behavior of misaligned tooth pairs. The movement state of spline coupling can change from a periodic state to a chaotic state with the increase of speed. Under light load, the main resonance speed of system may be modified due to changes in the load. The existence of misalignment promotes the vibration intensity, advances the main resonance speed and increases the instability of spline coupling. In addition, a test bench for the misalignment spline coupling was developed to measure the vibration acceleration signal, and the effect of the misalignment on the dynamic behavior of spline coupling was discussed.
