| Abstract: | Research purposes:The introduction is given to the filled polyurethane upward adjusting bowl rubber bracket used on two bridges in the integrated experimental section for the ballastless track of Suining-Chongqing Railway. Research results:The tests are done and comparisons are made for the characteristics of bracket structure, selection of materials for upward adjusting,adjusting process and pre-adjusting and post-adjusting properties of the bracket.The test result shows this method of upward adjusting can well satisfy the requirements of high-speed railway and passenger dedicated line for upward adjusting,with easy operation,reliable property and rational cost. |
