英文摘要：

The thermoelastic coupling stability of the axially moving beam under the action of uniformly distributed tangential follower forces was investigated.The differential equation of motion for the axially moving beam under the action of uniformly distributed tangential follower forces was established,and the eigenequation for the axially moving beam with two kinds of boundary conditions subjected to follower forces was derived by a normalized power series method.The first three orders dimensionless complex frequencies of the system were calculated,and the effects of the dimensionless moving speed,the dimensionless thermoelastic coupling factor,the dimensionless follower forces on the stability of the axially moving beam in the thermoelastic coupling case were analyzed.
