滚筒直径 [gǔn tǒng zhí jìng]
diameter of cylinder
- 摘要对在用车工况法尾气排放检测用3轴6滚筒重型底盘测功机的滚筒技术规格包括滚筒直径、第1轴和第2轴滚筒中心距、第3轴的滚筒与前两轴滚筒中心的中心距、第3轴滚筒相对于第1轴滚筒高度布置进行了研究，以保证被试柴油车在底盘测功机上正常运行，保证烟度排放的安全和准确测试。
In order to meet the requirements of safety and accuracy of smoke emission test for heavy-duty diesel vehicles, the specifications of roller in heavy-duty chassis dynamometer are studied including roller diameter, the distance between axes of first two axles, the position of third axle relative to first two axles both horizontal and vertical. - 文摘:在理论研究的基础上，将影响采煤机装煤性能的4个主要因素即滚筒叶片直径、滚筒转速、螺旋叶片内、外螺旋角做为设计变量，滚筒装煤生产率为目标函数进行了优化设计，并进行了分析。
Abstract: Derived from theoretic analyses are four factors gove rning the loading performance of the spiral drum,namely diameter,rotational spee d,in and out_slope_angle of the spiral.Taking the four major factors as design v ariables and the loading efficiency as the aim function,optimization experiment s were carrid out.
