Abstract:
A bending motion equation of a tilting drive shaft with rigid multi-supports is derived by theorem of the motion of mass center, method of Galerkin and Heaviside function. Approximate steady-state solutions of the main resonance are obtained through multiple scales method. The shapes, maximum amplitude, stability and amplitude jump of main resonance are analyzed. The results show that the bending motion equation is the Duffing one. Every span shaft in main resonance affects each other. The shape of main resonance of every span shaft is the same as that of a shaft with two supports. The maximum amplitude of main resonance is located at the maximum span shaft. When a drive shaft is in main resonance, the amplitude jump is possible. The interval length of frequency of amplitude jump is very small, and the frequency is a little smaller than the natural frequency.
