Abstract
The dynamic responses to harmonic and transient excitation for a multiple-point meshing mechanism with flexible support have been studied. First, the system’s frequency transfer functions were developed and steady-state outputs to a cosine excitation were obtained by both frequency-response and Laplace transformation methods. It is shown that by the appropriate choice of design parameters, the dynamic torque in the basic shaft for a given frequency excitation can, in theory, be reduced to zero. The system’s responses to step, impulsive, and ramp function excitation are also analysed. Furthermore, The maximum torques in the torsional bar and basic shaft are discussed which is an essential consideration for the strength design of these key elements.
