Abstract: Based on the theory of mathematical physics equation, the
joining conditions are proposed to establish the vibration equation of
train-bridge (track) system. The joining conditions include the equilibrium
condition of contacting forces between wheel and rail and the displacement
condition. Only when the joining conditions are satisfied, the equation of
the system is well-posed. The joining conditions are not
satisfied for the equation of the system currently in use.
Train and bridge (track) are regarded as a whole system and the joining
conditions are formulated. With the principle of the total potential energy
for formulating the system matrix equation, the
equation of the system is founded which can make the system well-posed.
