| Abstract | Recently, bus manufacturing is majority built on used chassis. The used chassis will be maintenance before assembly. The minority is built on own design chassis. However, the chassis manufacturing processes is quite very long throughputs, which lead to low production rate. This study aims to reduce chassis platform production time by designing of production jigs. Chassis technical data and information was collected in Cherdchai Industrial. The strength analysis by simulation with ANSYS workbench. It was found that the weakest point has SF 1.60. Moreover, the lock pin also need for changing of materials. Standard time for production of each sub-assembly was calculated. It was found that production rate of 2.3 chassis/day is achieved based on 2 workers. The 2 workers yield about 90% increasing in production rate compared to 1worker and %idle less than that of 4 workers. 6 workers with additional 2 jigs yields production rate of 5 chassis/day. The additional 2 workers yield about 25% increasing in production rate compared to 4 workers system. |
