sheared bar meaning in English
剪切刀片
Examples
- 3 ) a study is carried out to understand the changing rule of ultimate load and stiffness with the different reinforcement ratio of anti - punching shear bar . the increasing speed of the ultimate load is slower than that of the reinforcement ratio is indicated
3 .对不同抗拔钢筋配筋率的钢筋混凝土承台-钢柱脚抗拔极限承载力和刚度变化规律进行了计算分析,发现了随着承台中抗拔钢筋配筋率的提高,其承载力提高的比例逐步减小的规律。 - One specimen is fitted up with anti - punching shear bars and the other is not . 2 ) the elastic - plastic analyses of two experimental elements under uniaxial reversed loads are made by ansys ( a finite element analysis program ) and the results of analysis match the experimental results very well
2 .进行了钢筋混凝土承台-钢柱脚试件的弹塑性有限元建模,用ansys有限元程序对其进行了全过程弹塑性分析,计算结果与实测结果吻合较好。 - It still works well when the mulched straw is more then lot / ha . ( 3 ) an experiment was conducted on a self - made testing equipment to investigate the chopping properties of wheat straw under different conditions . on the basis of testing results , main cutting curves of wheat straw were given under different cutting speeds of rotary blade , with different straw lengths , different moisture contents , different cutting position , different thick of knife edge , with and without shear bar
( 3 )为了研究带状粉碎防堵装置对麦秸的切碎效果,在特制的实验台上,应用了虚拟仪器测试技术对不同处理的麦秆进行了切断试验,得到了在不同切割速度下对不同长度、不同含水率的麦秆、麦秆的不同切割部位以及有定刀和无定刀情况下的切断率,为麦秸粉碎装置的设计提供了依据。 - In this thesis , a new strip chopping anti - blocking mechanism and a new no - till planter operating well in heavy straw mulching condition are developed from the following aspects : ( 1 ) in order to solve the problem that the no - till planters can not work well when the mulched straw is long and thick , especially in the double cropping area of huabei plain where the winter wheat gives a high yield , a new strip chopping anti - blocking mechanism was developed . it consists of a group of rotary blades , a narrow tine opener , a shear bar , a hood and a deflector
在以下几个方面进行了较为深入的研究: ( 1 )在对国内外免耕播种机防堵装置研究的基础上,针对华北一年两熟地区麦收后地表覆盖量大的特点,通过对驱动式和从动式防堵装置的对比实验,设计出一种具有高效防堵能力的带状粉碎防堵装置,该装置由组合刀片、开沟器、定刀片、罩壳和导草扳组成。 - The curves showed that the moisture contents of straw and the shear bar are the main factors impacting the cutting ratio besides cutting speed . the speed of 40mm / s is necessary to cut off wet straw . ( 4 ) the testing results indicate that the rotary speed of the blade axle need to be more then 1230 rpm ( rotary radius of the blade is 25cm ) to cut off straw ( with moisture content less then 20 % )
试验结果表明,对于干的长秸秆,刀片切割速度达到15m / s时,切断率达100 ;对于干的短秸秆,刀片切割速度需达到20m / m / s以上;要切断湿秸秆需要有40m / s以上的切割线速度;加定刀与不加定刀对于切断麦秸这类软质秸秆是非常重要的,其切断速度差别很大;另外,麦秸不同部位所需要的切断速度也是不一样的,根部较之顶部和中部更难切断。
