A METHOD FOR THE MEASUREMENT AND ANALYSIS OF DYNAMIC LOADS

METODIKA IZMERENIIA I ANALIZA DINAMICHESKIKH NAGRUZOK, DEISTVUIUSHCHIKH NA PUT'

Experimental research on the dynamics of roadbeds and rolling stock serves to establish permissible speeds and loads for rolling stock. As a method for such experimental research SZD has adopted a complex analysis of both rolling stock and fixed plant. This paper describes the experimental track sections; the basic responses characterizing the action of rolling stock on rails, ties, ballast and subgrade; and the methods for measuring the responses of the track structure. Extensive use of strain gauges is necessary for the dynamic measurements. Other types of instrumentation for deflection and deformation are also described.
