前言苏联技术科学博士Д.А.邱达柯夫教授在他的著作中,对研究中耕拖拉机机组的行驶直线性曾提出了确切的计算公式。但是,这些公式中的某些数据,在目前的测试技术条件下,通过田间试验很难测得。因此,它们就只能局限在理论研究的范畴之内,而不能用来进行实际的运算。本文作者在Д.А.邱达柯夫的基础上,对这些公式作了进一步的研究,并设计了相应的电测仪器(转换器),以便在田间试验的条件下,能够获得利用新公式进行运算时所必要的数据。
Preface Professor of Technical Science, USSR Д.А. Professor Qiu Dakoff In his writings, exact formulas have been proposed for studying the driving straightness of cultivating tractor units. However, some of these formulas are difficult to measure through field trials under the current testing conditions. Therefore, they can only be confined within the scope of theoretical research, and can not be used to carry out actual calculations. On the basis of Д.А. Khodakov, the authors made further research on these formulas and designed the corresponding electrical measuring instruments (converters) so that under the conditions of field experiments, the new formula The data necessary for the operation.
