犁面压力场分布问题的试验研究,对正确了解犁体外载有着重要的意义。随着现代计算技术的发展,电子计算机的广泛应用,现在科研人员正在探索根据土壤在犁面上运动的流场理论,借助于电子计算机,试算出犁面上的压力场分布。但用“流场理论”算得的压强计算值,有待实践检验。因此,测定犁面上各 The experimental research on the distribution of plow surface pressure field is of great significance to correctly understand the plow body external load. With the development of modern computing technology and the widespread application of electronic computers, researchers are now exploring the flow field theory based on the movement of soil on the plow surface. By means of the electronic computer, the distribution of the pressure field on the plow surface is calculated. However, the calculation of pressure calculated by “flow field theory” needs to be tested by practice. Therefore, the measured plow surface each
