THE INFLUENCE OF THE WHEEL CONICITY ON THE HUNTING MOTION CRITICAL SPEED OF THE HIGH SPEED RAILWAY WHEELSET WITH ELASTIC JOINTS
Journal Title: ROMANIAN JOURNAL OF TECHNICAL SCIENCES - APPLIED MECHANICS - Year 2011, Vol 56, Issue 1
Abstract
The axle hunting is a coupled lateral and yaw self oscillatory motion which is largely determined by wheel–rail contact geometry. The stability of this motion is an important dynamic problem that determines the maximum operating speed of railway vehicle. The progressive depreciation in the working time of the railway vehicles components can lead to the intensifying of the vibration level. In this paper is studied the influence of the variation of the wheel conicity on the hunting motion stability of the high speed railway vehicles wheelset with elastic joints and passive linear elasticity and dissipation forces in horizontal plane.
