Contact Stress Analysis on the Variation of Wheel Profile
차륜답면의 형상변화에 의한 접촉응력분포 해석
- Published : 2003.05.01
Abstract
Mechanical force acted on the rail wheel causes excessive wear and increases the maintenance cost. The present paper proposes newly designed wheel profiles in order to reduce the contact stress. Numerical analysis on the stress distribution of wheel-rail contact stress is carried out using ABAQUS, a commercial finite element code. The result of KNR1/40 conical wheel is compared to those of the proposed wheels, all of which are arc wheel profile type.
