FRICTION BEHAVIOUR OF PTFE WHITE/AUSTENITIC STEEL FOR BRIDGE SLIDING BEARINGS WITH LARGE ADDED SLIDING PATHS IN RELATION TO SPECIFIC LOADING

项目名称：	FRICTION BEHAVIOUR OF PTFE WHITE/AUSTENITIC STEEL FOR BRIDGE SLIDING BEARINGS WITH LARGE ADDED SLIDING PATHS IN RELATION TO SPECIFIC LOADING
摘要：	IN BRIDGE SLIDING BEARINGS HAVING PLASTIC SLIDING LAYERS, THE COEFFICIENT OF FRICTION ALTERS WITH THE SIZE OF THE ADDED GLIDE PATH. A CONTINUOUS SLIDING TEST IS TO BE CARRIED OUT ON AN ADDED GLIDE PATH OF ABOUT 20000 M, WITH CHANGING TEMPERATURES, ON BEARINGS MADE OF A COMBINATION OF PTFE WHITE AND AUSTENITIC STEEL. THE BEARINGS ARE TO BE LOADED WITH 45 N/SQ MM TO DETERMINE AT WHICH SLIDING PATH THE COEFFICIENT OF FRICTION ESTABLISHED AS A DESIGN PRINCIPLE IS EXCEEDED. THE RESULTS ARE TO BE COMPARED WITH EARLIER TESTS IN WHICH THE BEARINGS WERE LOADED WITH 30 N/SQ MM.
