Abstract :

Ethiopia doesn`t manufacture any vehicle, it imports all the automotive needs from foreign. Recently some Ethiopian com-panies started to import engines, body structures and spare parts, and assemble locally in collaboration with the exporting foreign industries. Bishoftu Automotive and Locomotive industry (BALI) is one of the industries that imports and assemble the city bus in collaboration with the China`s Huwangai bus company. At this moment even though the industry assemble and distribute the city buses and other vehicles to it`s customer efficiently, there are some problems seen in the industry, such as; 1. Parts import with partially assembled are distorted during loading and unloading so that maintenance of these parts need extra cost. 2. Since the width of the Chassis is greater than the width of the container during shipping, the end supports of the Chassis are cut off about 8 cm lengths from both sides. Reassembling of these cut parts took almost half of the manufacturing time of the full Chassis. 3. Fear of cost increment by the exporting company. 4. Since the structures import in lot, it has an impact on less quantity orders. 5. To some extent there is limitation in looking forward for modification and improvement. To solve the above problems this study suggests to design modular fixture to manufacture the bus Chassis Frame locally. Materials for fixture manufacturing are selected through scientific methods considering availability, cost and mechanical properties. Design analysis of the fixture elements are made both geometrically and mathematically in detail.
