主要生產檢驗眼鏡產品各項物理性能指標的儀器設備：太陽鏡智能檢測儀、鏡片沖擊試驗機、樹脂鏡片阻燃試驗機、樹脂鏡片摩擦試驗機、眼鏡架耐疲勞試驗機、眼鏡架鼻樑變形試驗機、拉力試驗機等眼鏡產品的成套檢測設備。Because expansion valves are high precision processing components, factory in its internal adjustment of the body parts are processed in a state of complete thermostatic, the temperature of the gas filling kits are demanding more consistent not detect leaks, in the completion of the expansion valve assembly also undergo strict testing and fatigue resistance aging sampling, the construction expansion valves : 1 : indeed temperature temperature kits ; 2 : temperature gas or liquid filled with the expansion corrugated ; 3 : spherical valve seat ; 4 spherical valves ; 5 : spring ; 6 : overheating degrees adjustment screw spacer and screw ; 7 : internal and external ( h - type ) sealed pieces ; 8 : thrust poles and corrugated of spacer ; 9 : fati ; 10 : capillary, and so on
因為膨脹閥是屬于超高精密加工的零件，在工廠對其內部調整機構零件的加工都在恆溫狀態下完成，其中的感溫包的氣體充填更是要求嚴格一致不允許一絲泄漏，在完成裝配的膨脹閥還要經過嚴格的測試和耐疲勞老化抽檢，膨脹閥的構造： 1 ：感知溫度的感溫包； 2 ：感溫氣體或者液體充填膨脹波紋腔； 3 ：球型閥座； 4球型閥； 5 ：彈簧； 6 ：過熱度調整螺絲墊片和螺絲； 7 ：內部和外部（ h型）密封件； 8 ：推力桿和波紋腔墊片； 9 ：閥體； 10 ：毛細管等等。The opening stress and the life of crack growth is calculated and compared with the test results and the experience formula. the feasibility of the newman theory of opening stress used in the high strength steel is validated. then through the slice synthesis method, the three dimension surface crack of the weld joint of cone - cylinder is decomposed into many plane through cracks
本文將基於裂紋閉合現象建立的帶狀屈服模型，用在平面貫穿裂紋中，計算此時的裂紋張開應力和疲勞裂紋擴展壽命，與試驗結果和經驗公式比較，驗證newman裂紋張開應力理論在高強鋼中的可行性；然後，用切片合成法，把潛艇結構凸錐柱結合殼焊縫處的三維表面裂紋分解成平面貫穿裂紋，用帶狀屈服模型的理論來分析平面貫穿裂紋，得到裂紋沿深度方向的擴展速率，進而得到潛艇結構的疲勞壽命。According to european standard of wind turbine authentication, fatigue loads are selected by this dissertation as the main subject. so, a system of fatigue loads is designed. as the most important components, loads and life prediction of blades and tower of wind turbine are measured
結合國外風力發電機組檢測認證的項目內容，本文選取了主要參數中的疲勞載荷構建了風力發電機組的疲勞載荷測試系統，重點是對風力發電機葉片和塔架做了疲勞載荷分析和壽命預測。In this thesis, a load feedback low - frequency fatigue - testing machine controlled by microprocessor is developed. the machine adopts advanced electro - hydraulic servo system, which is controlled by micro - computer ( mcs - 51 single chip processor )
