結果發現，現行的以小四輪拖拉機為主要動力的耕作制度下，土壤剖面中耕層與犁底層的界面為「波浪型」 ，而年年進行秋翻的玉米田，其耕層與梨底層的界面為「平面型」 。Based on the analysis of the real work state of the tractor in the field, take the typical plough implement unit as an example ; a further study was made in this paper, including the theory of the automatic transmission and the quality of gearshift
本文以典型的犁耕機組為例，在分析拖拉機田間作業工況的基礎上，深入研究了拖拉機自動變速系統理論及換檔品質的問題，改進了換檔執行機構，用模糊控制方法對換檔品質進行了優化。About integrated control problems and optimal matching methods on plough implement unit, as an example in this paper, were discussed using fuzzy logical control theory. it gives a practical and referenced method on study auto - control of walking implement combinations
本文以典型的犁耕機組為例應用模糊控制理論，探討了犁耕機組的綜合控制問題及其最佳匹配方法，為研究行走式作業機組的自動控制提供了一種有實用價值的參考。According to the suh ' s theory of friction genesis and based on the change in topography with and without noise, it is assumed that the there is dynamic components of friction force in the area where uneven plowing grooves and pits or adhesive joined asperities are generated
根據噪聲與磨痕形貌的關系，本文提出了新的摩擦噪聲形成機理：在不規則的犁溝和麻坑或粘著微凸體形成區域，摩擦力有動態成分。Second, c language was used to optimize the parameters of exchanged direction structure, and dynamic design technology was used to simulate the action of exchanged direction structure, and the interference test of exchanged direction structure was done
然後運用c語言程序設計對水平換向雙向犁的換向機構進行優化設計；運用動態設計技術對換向機構的運動特性進行動態模擬模擬運動分析，對換向運動過程進行干涉檢驗。In this paper i calculate the reasonable possession quantity of port handling machineries with chance - constrained linear programming. first in the paper is the background and meaning of this research ; then analysis present situation of port machinery management both in practice and theory ; in chapter 3, i qualitatively discusses characters influencing machinery quantity, which include lifting ton, intact rate and using rate, age of machinery, machinery purchase and working cost and so on. in chapter 4, i take the influencing characters to mathematic model of chance - constrained linear programming, aiming to maintain the need of production and reduce machinery cost
文章首先介紹了選題的背景、意義以及主要工作；第2章介紹了港口機械管理在港口企業管理中的地位與作用，以及我國港口機械設備管理與配置現狀，並簡要介紹目前港機合理擁有量的理論研究方法；第3章從技術與經濟角度定性分析了各種因素對港機擁有量的影響，其中主要包括機械起運量、完好率與利用率、機械設備役齡、購置與營運成本等；第4章將各種影響因素引入模犁，提出以完成生產任務、機械成本最低為目標，應用隨機線性規劃模型計算港口流動機械合理擁有量的方法；第5章以大連港大港區為例對模型進行應用，選擇四種型號叉車為研究對象，對其歷史經濟與技術數據進行統計分析，其中重點對隨機變量單位臺時維修費用進行了正態分佈擬合。Low frequencies are related to the random property of soil rupture, whereas random vibration frequencies of the tractor - implement system are shown in the high frequency range
研究結果表明：低頻力與土壤振動裂縫等隨機因素有關，而高頻力則是由於拖拉機鼠道犁機組的振動引起的。A farm implement consisting of a heavy blade at the end of a beam, usually hitched to a draft team or motor vehicle and used for breaking up soil and cutting furrows in preparation for sowing
