Design And Analysis Of Train Brake Blocks
Subject area: Science,Engineering and Technology · Area of research: Mechanical Engineering
Abstract
This paper focus on the design and analysis of locomotive brake blocks. The brake is a critical feature in order to retard and stop the railway vehicle within minimum possible time. It is must for all vehicles to have proper brake system. The purpose of braking action is to perform controlled reduction in velocity of the vehicles, either to reach certain lower speed or to stop a fixed point. In this paper stopping distance, braking time and braking efficiency are calculated for three moving conditions of locomotive (moving on level, moving up and moving down) and braking force and brake blocks length are also calculated for the tread brake. The existing air brake system of railway coach has the following drawbacks due to excessive brake force on the brake blocks ? thermal cracks on wheel tread, brake binding and reduced life of brake blocks. The analysis is done by applying three different materials Grey Cast Iron, Low Carbon Steel and High Carbon Steel for Locomotive brake. This paper is to overcome drawbacks by changing the brake blocks length. Structural (von-Mises stress, effective strain) behavior of brake blocks are computed by theoretical approach. SolidWorks software is used for modelling. Structural (von-Mises stress, effective strain) behavior are analysed by using ANSYS software.
