犁體曲面 的英文怎麼說
中文拼音 [lítǐqūmiàn]
犁體曲面
英文
plow bottom surface-
In the course of working, ， the plow will make use of the shuttling method so that it can dig alternately either on the left or on the right. compared to the unilateral plow, it can improve the productivity because it can help leave off the soil 、 take from the consumed energy and reduce the empty journey. to meet the requests above, we will use a remote cylinder with both a small cubage and double functions, approximately designing the plow to be columniform and symmetric. after the experiment for a period in the field, we found that the most frayed areas had happened at the places of both plow shank and share and at the same time the base of the remote cylinder had ruptured suddenly
與單向犁相比，其優點在於：耕地無開、閉壟，地表平整，降低了耕后整地的能量消耗，減少了地頭的空行程，因而大大提高班次生產率。為了滿足犁體梭式作業的要求，我們採用了一隻小容積雙作用的液壓油缸；同時對犁壁曲面的形狀採用了近似圓柱形的對稱設計。但經過一段時間的田間試驗，我們發現：該犁犁胸部分的犁脛和犁鏵上的犁尖在工作中磨損較為嚴重；主犁梁和油缸缸體的連接部分（即油缸底座）突然發生了斷裂，造成整個犁體無法正常工作。In this thesis, the technology of visual fictitous design was used to design the level exchanged direction and double direction plough. first, the traction force formula of cylindrical plough face based on the prior study was deduced, and the forces of the solid model of circumrotatory pin was calculated, and visual dummy design technology was applied to analyse the force of circumrotatory pin and the parameter of pin
其次在前人研究的基礎上推導出圓柱型犁體曲面的牽引阻力公式；根據該公式計算出旋轉銷三維實體模型所受的力，根據該力運用可視化虛擬設計技術對模型進行受力分析，對旋轉銷的參數進行合理設計；根據牽引阻力公式計算出安全螺栓所受的力，根據該力運用虛擬設計技術對安全機構進行設計。The thesis had done the theories analysis in detail and built the relevant mathematics models aiming at the mechanics characteristic about the lodging of stalk, the elastic and plastic deform of stalk under the action of the transverse loads, the mechanics condition which causes stalk pushed, the relation between the speed of unit and the surface radius of ski, the relevant location between the thickness of the compressed stalk and action location of load, the relevant location between the mating device and plough, the coefficient of overturning soil under the thickness of the compressed stalk and so on. in addition, the computer aided analysis and simulating experiments in field were acted by choice
本文對秸稈自倒伏力學特性；橫向載荷作用下的莖稈彈塑性變形與秸稈被推倒的力學條件；機組作業速度與滑撬曲面半徑的關系；秸稈壓實厚度與加載作用點的相對位置；配套裝置與犁體相對位置；秸稈壓實厚度下的翻垡系數等，進行了較詳細的理論分析並建立了相關數學模型。在此基礎上，本項研究還選擇性地進行了計算機輔助分析和田間模擬試驗。
