 note = {Mechanical instabilities in a.c, Nb-Ti superconducting wire are theoretically investigated. We derived the expressions for the temperature rise of the SC wire due to the friction between the wire and the bobbin to estimate the quench current degradation induced by mechanical disturbances. The quench current levels were calculated for different conditions of frictional force and current ramp ratc. It is confirmed that a certain frictional force brings about the lowest quench current level. It is also found that the quench current degradation induced by mechanical disturbance may be hard to occur when the current increases rapidly.},
