第一級檢驗-
Slurry erosion tests were carried out with the manufactured test apparatus in order to study the erosion properties of the polyurethane composites. the results show that the wear resistance of silicon dioxide reinforced polyurethane composites decreased with the increased amount of particles, and the wear resistance of the alunima reinforced polyurethane composites first increased but then decreased. the wear resistance of the alunima reinforced polyurethane composites processed with kh550 coupling agent were maximum at the volume content of 15 %
試驗結果表明，聚氨酯復合材料的沖蝕磨損性能隨白碳黑體積分數的增大而降低，隨al _ 2o _ 3顆粒體積分數的增大先升高而後降低；經過偶聯劑kh550處理的al _ 2o _ 3顆粒增強復合材料耐磨性比經過kh560處理的復合材料高；經過偶聯劑kh550處理的al _ 2o _ 3顆粒增強復合材料在體積分數為15時具有最佳的沖蝕磨損性能。 -
In order to set up the dynamic model of swimming micro robot, this dissertation builds up the statics model and analyses the micro motion amplifying performance of micro robot mechanism, builds up the vibration model of micro robot and analyses the vibrating performance without and with damp, researches the propelling force of driven wing and the resistance of micro robot in liquid based on the theory of flat board resisting stream, builds up the dynamic model of swimming micro robot for the first time in nation and analyses its swimming performance which is influenced by driving signal frequency, amplifying performance of main machanism, area of driven wing, character of fluid and so on. this dissertation manufactures the micro robot and sets up the experimental environment and tests the amplifying effect and the vibrating performance
本文建立了主體機構靜力學模型，研究了主體機構的結構參數對微位移放大性能的影響；建立了主體機構振動模型，研究了主體機構在無液體阻尼和有液體阻尼情況下的振動特性；根據流體力學平板繞流理論，研究了驅動翼產生的推進力和微機器人在流體中受到的阻力；在此基礎上國內首次建立了泳動微機器人的動力學模型，並對模型進行了深入的研究，詳細闡明了驅動信號頻率、主體機構放大性能、主體機構振動特性、驅動翼面積、液體性質等因素對微機器人泳動特性的影響。 -
In practical application, the m10 180 bolts, which are installed in the head cover of the torque divider of ts5560 special automobile, sometimes fracture all of a sudden. according to the tests of acceleration, stress and strain, and the exciting test, it is resonance vibration that leads to the compound - bending fatigue fracture of the bolts. the exciting force caused by drive system, transmitted through the torque divider, produces a 1000 - 1500hz cyclical excitation at the junction of the bolts and head cover, which causes the first order bending resonance vibration of the bolts
通過加速度、應力應變測試實驗和激振試驗的研究，發現ts5560特種車分動器取力器氣缸端蓋m10 180螺栓斷裂問題是由於共振引起的雙向彎曲疲勞斷裂：傳動系統工作所產生的激勵，經過分動器結構的傳遞（特別是分動器一階扭轉模態的放大） ，在螺栓的連接處產生1000 1500hz的振動激勵，其導致螺栓一階彎曲共振，在螺栓一階彎曲模態的阻尼比較小的情況下，使得螺栓產生較大的共振響應，導致螺紋處的彎曲動應力較大，疲勞壽命較低。 -
According to present situation of brand equity, for the first time, five important brand equity factors were extracted from brand features by applications of principal component analysis and factor analysis methods, they were brand status, customer - recognized value, brand image, brand creative abilities and brand executive abilities ; on the same time, five types of brand equity were divided with k - means cluster methods on the base of five brand factors, they were leading brand, matured or ripe brand, concrete brand, customer - based brand and creative brand. in order to extract brand equity strategy, correlation and linear regression analysis methods were used, as a result of analysis, four strategies were put forwarded including brand marketing strategy, marketing dividing strategy, marketing stretching strategy and marketing entrance time, applying nonparametric tests and duncan tests, five brand equities were also differed in many aspects
在品牌資產各組成要素中，應用主成分分析和因子分析方法，提取了五個品牌資產最重要的構成因子，首次提出品牌資產最重要的因子是品牌地位和顧客認知價值，其次為品牌形象、品牌創新能力和市場執行能力；根據品牌資產的構成因子，運用聚類分析法，對調查企業的品牌資產類型進行了分類，按照品牌構成屬性將企業分為領導型、成熟型、務實型、顧客導向型和創新型品牌企業；在對企業品牌策略分析基礎上，運用相關分析和線形回歸方法，求導形成品牌的重要策略因子，提出建立品牌資產最重要的策略因子是推廣策略，其次為市場分化策略、市場延伸策略和進入市場時機。 -
