THE INFLUENCE OF DIFFERENT RESISTANCE ON STABILITY OF CURVE JOINTLESS LINE

摘要

To study the influence of different resistances on curve jointless line with allowable temperature rise, three kinds of finite element models are established by ANSYS to calculate the allowable temperature rise respectively with 2mm lateral displacement in five different curve jointless lines when both longitudinal and lateral resistance are nonlinear. And then we compare the results of three finite element models with that of wavelength equal model. It is shown that the effect of resistance on the allowable temperature rise of curve jointless lines goes less as the curve radius becomes longer. These 3 finite element models can be adopted to analyze stability of curve jointless lines. Considering the difficulty in model and computational efficiency, the second model in the thesis is highly recommended when analyzing the stability of curve jointless lines.
