Computerized analysis of traveling wave vibration characteristics of aviation thin-walled spiral bevel gears
Aviation thin-walled spiral bevel gears are prone to traveling wave vibration. This study proposes an efficient traveling wave vibration analysis method based on the contact finite element model of the spiral bevel gears. The excitation vibration modes under the typical working condition is obtained through comparison to the modal analysis and harmonic response analysis. The resonance modes and frequencies are determined by Campbell diagram. The effect of thin-walled structure parameters on the traveling wave vibration of aviation spiral bevel gears is investigated. The results show that the traveling wave vibration of the gear is easily excited by the forward traveling wave and backward traveling wave resonance of 2nd nodal diameter/1st nodal circle, forward traveling wave resonance of the 6th nodal diameter, backward traveling wave resonance of 7th nodal diameter. The increase of gear blank web thickness will decrease peak stresses. The increase of conical web thickness and angle will decrease the peak stresses of compound vibration. The adjacent modals will aggravate the vibration. The decrease of the modal frequency spacing will increase the peak stresses.
期刊介绍：
The Journal of Strain Analysis for Engineering Design provides a forum for work relating to the measurement and analysis of strain that is appropriate to engineering design and practice.
"Since launching in 1965, The Journal of Strain Analysis has been a collegiate effort, dedicated to providing exemplary service to our authors. We welcome contributions related to analytical, experimental, and numerical techniques for the analysis and/or measurement of stress and/or strain, or studies of relevant material properties and failure modes. Our international Editorial Board contains experts in all of these fields and is keen to encourage papers on novel techniques and innovative applications." Professor Eann Patterson - University of Liverpool, UK
