    摘要:

    針對(duì)扇形噴頭球頭處的復(fù)雜結(jié)構(gòu)以及農(nóng)藥中固體顆粒對(duì)噴頭內(nèi)表面的沖蝕情況，運(yùn)用立體幾何方法建立了扇形噴頭基本結(jié)構(gòu)尺寸的數(shù)學(xué)方程,，并對(duì)其進(jìn)行力學(xué)分析,。結(jié)果表明，扇形噴頭球頭處x向磨損最嚴(yán)重,。通過(guò)試驗(yàn)驗(yàn)證了理論分析,，建立了時(shí)間和基本結(jié)構(gòu)尺寸的變化對(duì)磨損率的影響關(guān)系式。

    Abstract:

    The complex structure on the spherical-top of flat-fan nozzle orifices and the erosion situation of solid pesticide on the inner surface of nozzle were studied. Firstly, a mathematical equation of the basic structure was established according to the solid geometry. Secondly, the most significant wear in the x-axis of the spherical-top of fan orifices was concluded through mechanical analysis. Finally, the theoretical analysis was verified through the experiments, and the wear rate relationship was established with the spraying time and the dimensional change of the spherical-top of flat-fan orifices. 
