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.

Finite element analysis of transverse stiffness and strength of rubber parts for type SS9 locomotive′s axle-box pull-rod;

Static finite element analysis of transverse stiffness of air spring used in a car;

In the test and evaluation investigation of Baotou Huanghe River Bridge on Baotou-Shenmu Railway,it was found that the transverse stiffness of the Bridge could not meet the requirements in the codes and specifications,and it was determined that the Bridge must be strengthened and the strengthening design of the Bridge would be mainly based on the transverse natural vibration frequency.

Study of the lateral rigidity calculation for secondarysuspension with rubber side bearing on electric locomotive;

This paper describes the weaker lateral rigidity of the portal crane.

The calculation results of free vibration characteristics,lateral rigidity,the Sperling and Dickeeman comfortable standards are presented about Banqi-2 flat curved continuous rigid frame bridge of Nanning-Kunming Railway.
