The study not only involves the influence of tire lateral stiffness and tire inflated pressure on aircraft nose wheel shimmy on the basis of the model, but also finds that tire lateral stiffness and tire inflated pressure are one key tire parameter which influences shimmy.

The tire model is then applied to the frontal offset impact simulation of complete vehicle to analyze the effect of tire stiffness on the consequences of impact.

Signals from ABS,effective rolling radius,torsional stiffness and longitudinal stiffness are all used as parameters to monitor tire pressure.

It uses rim speed comparison, effective rolling radius, torsional stiffness and longitudinal stiffness as parameters and use different methods to monitor tire pressure.

The causes for the segment uplift are analyzed in terms of the shield attitude,the longitudinal rigidity of the tunnel,the length of the tunnel section where the simultaneous grouting mortar has not set and the property of the ground.

The different designs between urban rail transit and high speed railway are investigated,then the feasibility of reducing pier longitudinal rigidity in urban rail transit elevated bridge is derived from comparing these two types of railway.
