Autor: Jia Yuan Tao, Yu De Xu

Publikováno v: Applied Mechanics and Materials. 624:613-616

To solve the problem that there is vertical track profile irregularity with long wavelength and large amplitude a method of adjustment based on cubic spline interpolation was proposed in this paper. The key step of the method is to set up reference s
