旋耕机运动参数动态试验方法的研究

STUDY ON THE VARIABLE TEST METHOD OF KINETIC PARAMETERS OF TRACTOR AND ROTARY TILLER

介绍了通过计算机的处理与控制，在试验过程中用直接实现改变台车前进速度或动力输出轴转速的试验方法（简称动态试验法）来获取旋耕机运动参数与功率消耗的关系曲线，从而大大减少了试验次数，提高了试验的可比性及精度。本试验方法也适用于其它耕种机具。

This paper introduces a test method of directly cbanging forward speed orPTO rotationalvelocity of the vehicle with computer treatment and control in the process of tests( brieflynamed the variable test method ),then get the functional curves of the relation between ki-netic parameters and power requirement of tractor and rotary tiller.The variable test methodcan greatly reduce the frequency of tests and improve comparability and precision of tests.This test method is also suitable for other farming implements of cultivation.
