This paper brings forward two new calculation models on CWR's stability and analyses the CWR's stability in the condition of single wave curve when its initial curve wavelength is less than distortion curve wavelenth and double wave curve. On the ground of the potential energy stationary value theory,the formulas for stability calculation are developed and compared with the existing formulas. Based on this,the influence of the fastener resistance to temperature force is described in this paper.
