PARAMETER STABILITY AND VIBRATION CHARACTERISTICS ANALYSIS OF GEAR TRANSMISSION SYSTEM
Jixie qiangdu, 2019 Considering the time-varying meshing stiffness and gear backlash, a dynamic model of gear transmission system is established. The Floquet theory is used to obtain the approximate analytic solution and the stability boundary curve of the transmission ...
