Dynamic Analysis Of Passive Inclined Disc Opener

Mechanical Engineering

Inclined disc opener are used in order to open the soil in a farm during the seed sowing operation. Disc openers are used where uniform seed depth is required. It is also observe that draft force required for furrow opening is also reduced as compared to conventional type of furrow opener. Disc is continuously runs in a soil and when it is stop it takes a load of frame. During turning of tractor it takes a maximum load upto 150 Kgs with some depth. Since the disc is running in a soil with a tractor speed of 3.5 – 4 km/hr. The dynamic analysis is carried out by taking into consideration that the disc is rotating at a speed of 3000 mm/sec and it hits on the rigid body or stone for a short period of time of 5 e -3 second. In this paper analysis of disc is carried out by using an ANSYS software. The analysis is based upon some fixed design consideration such as design parameters diameter of disc, thickness of disc, construction, etc. When disc hits on rigid body for a short period of time it deforms and carries different types of stresses. Thus calculation of these stresses is very important for the safe design of disc, hence analysis has been carried out for same in this research paper. Disc opener also helps in minimum soil opening in order to conserve the moisture in the soil thus it helps in to increase the germination rate of seed.Tetrahedral meshing is used for the analysis of disc in order to achieve finest results.
