Design of experimentation for establishing empirical relationship of chaff cutting phenomenon energized by human powered flywheel motor (HPFM)

In India, animal husbandry is an integral part of the rural economy. Almost every farmer’s family keeps at least a cow and two oxen. The forge scarcity is always faced in dry season, means the available forage must be properly used and waste minimized. The chaff cutter always suggested for optimum use of forage. But the availability power is not reliable and hand operated chaff cutter results in high tiredness to the operator. The human powered chaff cutter is developed without any design data. The set-up consists of three main systems namely, (i) Human powered driven flywheel motor, (ii) Transmission between flywheel shaft and process unit shaft, (iii) Process unit i.e. chaff cutter.This paper presents detailed design of experimentation to be performed for establishing empirical relationship of chaff cutting phenomena energized by human powered flywheel motor. It includes identification of variables, dimensional analysis, test envelope, test point, test sequence, measurements and instrumentation, data checking and rejection and method of data analysis
