摘要
本文对电测法测定谷物茎秆切割力中存在的问题及原因作了理论上的论述,并提出用系统的频率响应函数解决问题的途径和方法。此种方法对受冲击力作用的负荷测定具有普遍意义。
The author made a theoretical interpretation of the problem in measuring cutting force on grain stems with electrical logging method and gave the reason of it.
A practical methodology of frequency response function of the system as means of its measurement was contributed.
The methodology may find a wide application in measuring load from impactforce.
