DESIGN AND DEVELOPMENT OF A WEIGHT IN MOTION SYSTEM FOR INDIAN RAILWAYS

Abstract

Weight in Motion (WIM) in Railways is an innovative technology of measuring the train load in the dynamic feature. WIM is required for the monitoring of the railway tracks and the train wheels and thus help in controlling the no. of trains and passengers on the train and the particular railway tracks. In this presented report, we discuss the various types of WIM methods that are being used in the railways. The report briefly describes the principle, uses, advantages and demerits of various sensors. Next we discuss the progress that have been done in the field of railway WIM. Many researchers have developed different algorithm using different sensors, each having certain merits and demerits. After analysing the progress we discuss the need for the WIM, demerits of existing system and how we can overcome them. Next we discuss the model prepared and analysis done on it, to represent our result. After performing static and Dynamic Analysis on the Railway carriage we calculated our results and compared those with the standard ones. Finally piezoelectric sensor has been modelled using the Finite Element Analysis and the corresponding results have been plotted.
