Fist of all, on the basis of the research of agone boffins, this author investigates the interaction mechanism of bolts and rock, and introduces the elastic ? lastic analytical resolution which is consist of the liner structure, the equivalent reinforced wall rock and the original wall rock in the simple loading from the equivalent well - proportioned view ; this solution is very important meaning for the engineering design. on the basis of coulomb friction model, the author introduces the finite element equation of the contact problem in order to provide the academic foundation for the application of msc. marc. finally, combining the engineering practice of the non - linear analysis of shield tunnel through yellow river of the south - north water transfer and using the model of friction, the author researched the evolution law of stress and displacement field in the structure of grouted rock bolts, and analyzed the effect to the stress and deformation of surrounding rock mass due to anchor supports
首先，在前人研究成果的基礎上，對錨桿與圍巖的相互作用機理進行研究，利用全長錨固錨桿的中性點理論，從等效均化的角度來考慮錨桿對圍巖的加固作用，並推導了在簡單荷載作用下，含有襯砌、等效加固后的圍巖、原始圍巖三者的彈塑性解析解，對工程設計有著重要的參考意義；在數值模擬方面，以考慮錨固圍巖滿足規則化庫侖摩擦模型為基礎，利用虛功原理推導了接觸問題的有限元方程的計算格式，為開發運用大型商用有限元軟體msc . marc提供了理論根據，也形成了本文的理論基礎：最後，論文以南水北調東線穿黃隧洞穩定性分析項目為工程實例，利用本文所述的接觸問題的摩擦模型理論，對錨桿支護結構的應力場、位移場的變化規律進行了研究，分析了加錨支護對隧洞圍巖應力、變形的影響。On the basic of a great of literature reading and research on safety of side impact of the car, according to requirement of ece r95, applied madymo6. 2. 1 software, established simulation model of side impact of the car, researched the relationship between side rigidity of the car and passenger injury in side impact, which showed that during first impact the bigger side rigidity was, the more advantaged protection for the car and passenger in a definite range, and which drew a conclusion that the most serious part of passenger injury was pelvis during first impact. then detailed the substructure model by defining bodies, joints, contact types and contact characteristic, researched some improvement approach for side safety of the car, and then analyses a particular case, that was to say to fix vehicle door bar fender on between inner and outer plate of the vehicle door, analyzed the influence of passenger injury when the bar fender was fixed on different position, the result showed that the passenger injury was less when the bar fender was fixed on the height of vehicle door decorate bar. finally, a set of tests were performed, contrasting the simulation result with the test, analyzed the influence of the side rigidity of the car to passenger injury, which showed the test
本文在對汽車的側面碰撞安全性進行大量文獻閱讀和研究的基礎上，按照歐洲ecer95側面碰撞乘員保護法規的要求，應用多剛體動力學軟體madymo6 . 2 . 1 ，建立了汽車的側面碰撞模擬模型，研究了汽車的側面剛性對乘員損傷的影響，結果表明在「一次碰撞」中，在一定范圍內汽車側面剛性越大，越有利於汽車和乘員的保護，同時得出結論，即在「一次碰撞」過程中人體損傷最嚴重的部位是骨盆;然後通過定義各剛體、鉸鏈、接觸類型以及接觸特性，對該模型進行子結構細化工作，研究了加強汽車側面安全性的若干改進措施，並進行了一個特例分析，即在此模型的車門內外板之間安裝了車門防撞桿，分析了當車門防撞桿安裝在不同位置時對乘員損傷的影響，結果表明防撞桿位於車門裝飾條的高度時，對乘員的損傷較小;最後進行了一組側面碰撞試驗，通過試驗和模擬結果的對比，分析汽車的側面剛性對乘員損傷的影響，表明試驗和模擬結果是一致的，從而證明了模擬模型的有效性以及模擬結果的正確性。Thereby, this paper has carried through an in - depth study on wear mechanism between tool joint of drill pipe and casing, problems caused by wear and measures to deal with wear based on researches at home and abroad. the research contents include : in order to reveal mechanism of wear occurred between tool joint and casing, distribution of the contact pressure between the tool joint and casing for different loads was obtained with finite element method. furthermore, the mathematical model of maximum contact pressure and the wear depth on casing was established
所以，本文在國內外研究的基礎上，對鉆桿與套管摩擦磨損的機理、引發的系列問題及其預防措施進行了深入研究，研究內容主要包括：為探討鉆桿接頭與套管摩擦磨損的機理，採用有限元法研究了不同載荷下接頭與套管之間接觸壓力的分佈規律，並建立了最大接觸壓力與磨損量的數學模型。
