ABSTRACT:
Puddling is a crucial process in rice cultivation, involving the preparation of the soil in a flooded field to create a soft, muddy seedbed. There are two classifications for puddling: full cage and half cage. Full cage puddling involves replacing the rear wheels of the tractor with steel paddle wheels, which are used to till the rice paddies directly without any additional implement. In the half cage puddling, the rear wheels remain on the tractor, and a smaller cage or paddle wheel is attached to the outside.
Considering the field size, the operator often releases the clutch very quickly after a speed or direction change. This generates torque spikes, which are harmful to Transmission Gears and Clutches. This can lead to gear teeth bending fatigue failure due to repeated higher bending stresses.
In this paper, a study related to how to reduce overall product development time by simulating bending fatigue failure of gear in lab environment. A systematic approach is used to understand the field application, data acquisition, Data analysis, new test stand development and replication of failure mode in lab environment,
Objective and Background:
Based on the field operating condition, the target is to simulate torque behavior in the lab environment. From the field application details, field study and acquired data, it is possible to generate soil resistance in lab environment.
This paper focuses on the methodology and systematic approach to understand dynamic behavior of the tractor in puddling operation and to develop the new test stand to replicate the field failure mode in lab environment.
Results and Conclusion:
In this paper, it explained how the reduction in overall development time by simulation of field failure mode in lab environment and, by this it is possible to conduct different design iterations quickly and finalize right design on time. From the strain plot, we understand the impact of torque on clutch and Gear box. Different soil resistance is analyzed and finalized worst scenario from acquired data, identifying the root cause and then, through the new developed test stand, simulated file failure mode in lab environment.
