Among the six Models, Model A and Model B can be used to study the vehicle stability and curve negotiation under different track situations. Model C and Model D can be used to carry out the stability, dynamic curving behavior and ride comfort of the high-speed passenger car. Model E and Model F are three-dimension train dynamic models which consist of three cars (head car, intermediate car and tail car).

In this thesis, two chemical structural models were constructed based on several structure parameters derived from FTIR and 13C NMR data, which were processed by curve-fitting and curve-resolved. Modified models were obtained by simulation oftheir molecular vibration spectra using Cerius 4.6/IR module andthe structural parameters from 13C NMR. Potential energy, bondenergy and non-bond energy of the minimum-energy conformations of coal macromolecules were calculated by molecular mechanics calculation and molecular dynamics simulation. These results demonstrate the importance of hydrogen bonding and van der Waals interactions in the formation and stabilization of coal macromolecular structure, and a strongest tendency of hydrogen bonding interactions to increase with the coal molecules but the Coulombs force.
