| Abstract: | Ploughing is one of the most widely used methods of cultivated land.Good plough surface not only can make the soil meet the requirements of ideal agronomic operation,but also can reduce the energy consumption during ploughing.The geometric characteristics,performance parameters,ploughing process and design methods of plough surface are described and analyzed.This paper summarizes various research methods based on the movement and force of soil embankment in ploughing process,and summarizes the methods of plough surface design from experience design,geometric forming line method,soil trace simulation method,plough surface design based on ploughing process,computer aided design,high-speed plough surface design and so on.Current research situation,summarized that the method of designing plough surface by using computer aided design technology combined with advanced and reasonable ploughing operation model is the development trend in the future. |
