GEAR VIBRATION CALCULATION METHOD, PROGRAM, AND RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To predict highly accurately an engaging vibromotive force of a gear and a vibration of a vibration transmission system including a rotator having the gear and a support for supporting the rotator, concerning a technology for calculating the gear vibration. SOLUTION: Concerning a manual transmission for an automobile equipped with a plurality of gears and a case for supporting them, a tangential load Fq* working along a common tangent of both base circles of gears between tooth flanks of two gears interlocked mutually is calculated as a composite value of (a) a response displacement load Fq*s working between interlocking tooth flanks where the gears are interlocked mutually in response to a relative displacement between interlocking gear teeth of the gears and (b) a dynamic load Fq*d working between the interlocking tooth flanks of the gears in response to a fluctuation in the gear radial direction of an interlocking contact point where each tooth flank of the gears is brought into contact mutually during an interlocking period. A response of the case to the vibration whose vibromotive source is the gears is calculated on the basis of the calculated tangential load. COPYRIGHT: (C)2006,JPO&NCIPI
