A model which exhibits the essential features of track buckling mechanisms is used. It is represented by four bars constrained at the interconnecting joints by spiral springs. The bars deform axially according to Hooke's law and the law of linear thermal expansion, but are rigid in bending. The author analyses the mathematical model according to three different assumptions. He compares the results obtained and draws conclusions as to the critical temperature at which buckling can occur and the assumption which is most representative of track buckling.
