BRAKE BLOCK DYNAMOMETER LABORATORY OF THE INDIAN RAILWAYS
The paper describes the Brake Block Dynamometer Laboratory of the Research, Designs and Standards Organization of the Indian Railways at Lucknow, for developing the designs and materials of brake blocks, both metallic and nonmetallic, which are used in train braking. The brake dynamometer can simulate trains working up to speeds of 250 km/hr with axle loads up to 25 t. It works on the principle of gyrating masses, which can be run up to the required speeds with power supplied by a Ward-Leonard set and braking can be simulated under controlled conditions. The equipment has sophisticated electronic/electrical controls and its operation can be manual or automatic. Besides being displayed on dial and/or digital indicators, the various parameters can also be recorded with an ultraviolet recorder. A 12-channel dotted line recorder can be used for temperatures. The scope of investigations in progress and those to be taken up in future in the laboratory are also briefly described.
