The energy required for tillage processes accounts for a significant proportion of total energy usage in crop production. Development of more efficient tillage tools is essential to reduce the energy consumption and to increase agricultural production. Although there are some methods which are currently being used to analyze and design agricultural machineries (i.e. empirical, analytical and continuum numerical (Finite element method) methods), each of which has its own shortcomings. In this study, as a novel approach discrete element method was explained and then the possibility of using discrete element method to design agricultural machineries was investigated. For this purpose, draught forces and soil profile measured by Saunders (2002) for soil-mouldboard plough interaction was simulated. Simulation results showed that draught forces can be predicted with a maximum relative error of 20.5%, while soil profile was simulated with 9.3 % relative error. Results of the study proved that the discrete element method can effectively be used to design agricultural machineries.

Tarımsal üretim için kullanılan enerjinin çok büyük bir kısmı toprak işlemede kullanılmaktadır. Bu nedenle tarımda verimliliği artırmak ve enerji kullanımını azaltmak için enerji gereksinimi düşük olan tarım alet ve makinelerinin geliştirilmesi gereklidir. Tarım makinelerinin analiz ve tasarımı için çeşitli metotlar kullanılıyor olsa da (örneğin: deneysel, analitik ve nümerik (sonlu elamanlar) metotlar) bu metotların her birinin çeşitli dezavantajları bulunmaktadır. Bu çalışmada yeni bir yöntem olan ayrık elemanlar metodu tanıtılmış ve bu metodun tarım makineleri tasarımında kullanılabilirliği araştırılmıştır. Bu amaçla daha önce Saunders (2002) tarafından kulaklı pulluk kullanılarak yapılmış olan deneysel bir çalışma, ayrık elemanlar metodu kullanılarak çeki kuvvetinde maksimum %20.5 ve ortalama toprak profilinde % 9.3 bağıl hata ile simüle edilmiştir. Çalışmanın sonuçları ayrık elemanlar metodunun tarım makineleri tasarımında verimli bir şekilde kullanılabileceğini göstermiştir.
