Abstract Research purposes : Aiming at the difference between tie structural form and rigidity , the analysis is made for the influence on track response by tie elastic modulus by analysing tie static response.
Research methods : Based on Winkler Assumption and adopting continuous elastic grade beam method , the calculation method of tie static response is worked out with regarding the tie rigidity as influence variable and consideration of the influence on the tie response volume by the change of tie rigidity , such as displacement , striking angle , flexural torque and shear force.
Research results : The analysis method of tie structural static response is worked out, the distribution curves of tie response volume are given and the influence on tie response by tie rigidity is presented.
Research conclusions : The perfect analyses can be made for the static response of the tie on elastic foundation by adopting tie static analysis method. It shows the change of static response of the tie on elastic foundation becomes large with the increase of elastic modulus of tie.
