| Abstract: | This paper,on HTD(hydraulic transmision device)equipped railway bridge,espounds the throttlling quantity confined by longitudinal displacements of pier's top due to varying temperatures and braking force.Based on the reseach on throttle characteristics of an experimental HTD, the paper has advanced the measuring.method for throttlling and recomanded the opening of the throttle valve used in the research,and therefore demonstrated the technical feasibility of HTD's practical application. |
