DOI: 10.1016/j.jsv.2018.07.037
Abstract: Abstract The sub-harmonic resonance phenomenon exists in multistage gear transmission system. Collision motion leads the sub-harmonic resonance instability, which brings harm to system stability. So investigating instability conditions of sub-harmonic resonance and effects of fault… read more here.
