THE DIFFERENTIAL EQUATION OF RELATIVE ROTATION ANGLE DIFFERENCE OF INTERMEDIATE SHAFT OF DOUBLE UNIVERSAL (CARDAN) COUPLING WITH CONSTANT ANGULAR VELOCITIES OF INPUT AND OUTPUT SHAFTS

摘要

This paper analyses the relative rotation angle difference of intermediate shaft of Z. type double universal oupling in achieving the constant angulor velocities of the input and output shafts, and presents the differential equation of relative rolation angle difference of the intermediate shaft based on the sunplified model. In this paper, the nonlinear vibration equation is simplified to a linear one by keeping the first term of Fourier series expansion, so that the solution equation suitable for the practice is obtained.
