摘要
介绍了我国第一辆２５０ｋｍ／ｈ高速客车转向架试验研究结果。针对原设计造成该车蛇行临界速度低的情况，进行理论分析和试验台试验，提出了改进措施，提高了该车的稳定性。并进行了多达１２种不同工况的比较优化试验，为一系、二系悬挂参数的选取提供了依据。
The results of the test and research for the first 250 km/h high speed passenger car bogie in our country are described.In view of the low critical speed of hunting motion under the original design,theoretical analysis and stand test are carried out,improvement measures are provided,the stability of the car is improved.The tests for comparison and optimization under 12 different working conditions are carried out,which provides basis for selection of parameters of the primary and secondary suspensions.
