Abstract Underground mining is the regular happening work around the world, mainly in India for coal, iron ore, gypsum etc………….. Transportation of the material is the major criteria for underground mining most commonly locomotive trolleys, belt conveyors (or) screw type conveyors are used to carry the material from underground to surface. Locomotive trolleys are the most efficient transportation system for underground system even for human transportation also it can be used. Now all the mining companies are using belt type (or) screw type conveyors because of regular maintenance (or) replacement of locomotive trolleys, but screw conveyors and belt type conveyors are making heavily wastage falling from belt conveyors and crushed wastage from screw conveyor. This project deals with design optimization for improving the life of locomotive trolley. 3D models will be prepared according to company standards. FEM based analysis will be conducted on assembly to find the location of maximum stress. Static and model analysis will be carried out by applying suitable materials and modifying part by observing the above analysis.

INTRODUCTION BOGIE A bogie or truck is a wheeled wagon or trolley. The term “bogie” is used in british english, while a “wheel truck”, or simply “truck” is used in american english .In mechanics terms, a bogie is a chassis or framework carrying wheels, attached to a vehicle, thus serving as a modular subassembly of wheels and axles. Bogies take various forms in various modes of transport. A bogie may remain normally attached (as on a railway carriage/car or locomotive, or on a semi-trailer) or be quickly detachable (as the dolly in a road train); it may contain a suspension within it (as most rail and trucking bogies do), or be solid and in turn be suspended (as most bogies of tracked vehicles are); it may be mounted on a swivel, as on a railway carriage/car or locomotive, or additionally jointed and sprung (as in the landing gear of an
airliner).A bogie is a structure underneath a railway vehicle body to which axles and wheels are attached through bearings. The overall term is “running gear”, which covers bogies as well as vehicles with two, or more axles without any bogies .In this case, these axles are directly fitted to the vehicle body via guiding devices and springs, and for very low speeds even without springs . Purpose of running gears: Support of the rail vehicle body. Stability on both straight and curved tracks. Providing ride comfort by absorbing vibration, and minimizing centrifugal forces when the train runs on curves at high-speed minimizing generation of track irregularities and rail abrasion. Design principles: Railway bogies are complex subsystems in railway vehicles and contain brake systems, drive systems including gearbox coupling and traction motors for powered wheel sets, bogie frames with secondary spring systems and the wheel set subsystems, which are basically the assembly of two wheels and an axle. The focuses is on some general bogie design principles and especially design features that interact with the axle box bearing system .Directly connected to the wheel set and the bogie frame is the axle box containing the axle box bearing system. The axle box is very much linked to further subsystems and components like primary spring systems, axle box guidance, dampers, steering mechanisms of wheel sets, earth return devices as well as sensors to detect operational parameters and bogie monitoring systems. Further bogie-connected subsystems 85
