在我国南方深泥脚水田地区的农业生产中,机耕船具有特殊的优点,但是它的最佳总体布置和船体形状设计必须对机组动力学进行定量的动态分析才能确定.本文叙述了用电测法分别测定了空行时、旋耕时、犁耕时机耕船船底比压的大小和压力分布规律,为确定机耕船的总体布置和船底形状的设计提供依据. 本文对超低压膜片式比任传感器的设计与标定进行了简单的叙述.这样使我们能对机耕船机组动力学进行定 量分析成为可能。 In the agricultural production of deep mud paddy paddy fields in south China, the machine has the special advantage, but its best overall layout and hull shape design must be determined by dynamic analysis of the unit dynamics quantitatively.This paper describes the use of electrical measurement When the rotary tillage was carried out, the size and pressure distribution law of plow bottom pressure during plow tillage was measured, which provided the basis for determining the overall arrangement of plow trenches and the design of bottom shape.In this paper, The design and calibration of the sensors are briefly described, which makes it possible to quantify the dynamics of a plowman unit.
