犁体受力电测,多是测量六分力,测试工作量大、不易普及、影响精度的因素多,不能提供整机性能设计所需数据.本文以5马力机耕船的犁体、犁架为例,经过受力分析,提出了犁体受力电测的“三分力测量法”;以测量力的要素为内容,经过试验验证,该法可行. Plow force measuring, mostly measuring six points, the test workload is large, not easy to populate, affecting the accuracy of many factors, can not provide the whole machine performance design data required.In this paper, 5 horsepower plow tilling plow As an example, after the force analysis, put forward the “three component force measurement method” of the force measurement of the plow body force. Taking the element of measuring force as the content, this method is validated by the test.
