According to this method,four different 11-step algorithms with four different window functions which are rectangular window,triangle window,hanning window,and blackman window are designed. Analysis and simulation show that hanning window and blackman window with small lobes are less sensitive to errors. Seven different algorithms with the same phase shifting interval π/2 are designed by hanning window function,whose phase shifting steps are separately 5,11,15,39,51,76 and 101 steps.

The distribution of gear's contact stress, root stress, and contact engagement line in the engagement situation of gear pairs, were obtained on the base of explicit integration method. 3. Adopting the method of system matrix, the torsional vibration differential equation of general shafting was gained. The simple harmonic forms of excitation torque under the normal combustion or piston flameout of in-line engine and v-type engine were analysed. The decoupled algorithm of free vibration and forced vibration and the solution to the vibration damper's energy of resistance and the off-resonance calculation were studied.
