DESIGN AND ANALYSIS OF COST-EFFECTIVE COMPACT DISC HARROW

It is well-known that during tillage operations suprising items may appear below the soil surface in agricultural lands. Sometimes a stone/rock or solid root can cause major damage to the tillage equipments. These rocks and solid roots can cause major impacts on tillage equipment. In order to eliminate or minimize the impact of these forces, shock absorbing equipment is used that provides the connection between the disc harrow and the chassis. The most commonly used material for these shock absorbers is a rubber-based polymer known as vulkollan (polyurethane), which has a wide are of use in industry. Vulkollans are used to absorb the impact and wear out over time because of sun, climate and impacts. Therefore, in this experimental study, steel springs are used since they are much more durable. Modal analysis was conducted in order to investigate the mechanical properties of steel springs.
