The experiment procedure and analysis result about exteriorly extended end - plate connection with high strength bolt are introduced primarily ; each sample ' s dimension is given. the adding load equipment, measuring apparatus placed, measuring point established is detailed. adding load measure load and m - curve is produced ; the single span gabled frames horizontal displacement formula is deduced when the horizontal concentrated force is applied to it
重點介紹了外伸端板高強螺栓連接的實驗過程及實驗分析結果,介紹了各組試件的形狀尺寸、加載裝置、測量儀器安放、測點的布置等;給出加載方式及測出的m -曲線;計算出試驗節點的初始剛度;推導水平集中力作用下單跨門式剛架考慮節點半剛性的側移計算公式。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。The shear strength increases by 3 - 6 times after improvement through vane shear test and the resistance increases largely through cpt. the soft foundation treated by vacuum combined with surcharge preloading is very effective. second, the mechanism and some problems of vacuum combined with surcharge preloading were analyzed
通過十字板剪切試驗與靜力觸探試驗,加固後土體的抗剪強度一般可提高3 6倍,錐尖阻力與側壁阻力也有大幅增長,說明真空聯合堆載預壓加固軟土地基的效果顯著。
