Certain assumptions concerning creep coefficients of flange surface and wheel tread, and relation between static frictional coefficient at contact point and attack angle, between vertical load and eccentricity of wheel in lateral direction, and between slip ratio and tangential force, led to derivation of formula to determine value of allowable limit of derailment quotient of wheel being acted by stationary side thrust, for securing running stability of high speed railway vehicles; experiments using 1 to 10 and 1 to 5 scale model wheel set were made to prove theory; results of theoretical studies and tests are summarized.
