Abstract
Spanned—type development off the high-speed passenger&cargo transportation is the main rhythrn of the curreaat railway development in our ,improving the smoothness,safe reliability and amenity of train operation is one of the subjects about the high-speed train dynamics,In our country,it is almost to USe the foreign advanced oil—pressure damper for our newly-made quasi—high-speed and high-speed train so as to improve their
dynamic performance。In elerate turning the foreign hig蠡一speed train
oil—pressure damper to the homemade one and import,absorb the advanced
technology of the train oil-pressure damping,it is necessary to OWn the advanced
and reliable testing equipment of the oil—pressure damper,In this thesis,the high—speed train damper experimental bench is developed to serve testing damper’s dynamic characteristics and to present the strong guarantee for studying roundly it.
Firstly,the oil-pressure damper’s function on the high-speed train and its dynamic characteristics are introduced briefly and the structure and princip’le of the damper experimental bench at home and abroad,performance data and curves
of the damper tested on this experimental bench are analyzed in this thesis.
Secondly,the main tecbmotogy indexes of the high-speed train oil-pressure damper experimental bench are put forward and its conceptual structure is analyzed;position is introduced and the types of key parts of it are chosen; its process control me
