【摘要】：伴隨全球經(jīng)濟的快速發(fā)展，世界各國對于能源的需求越來越大，，面對日益緊張的陸地資源，人們逐漸將眼光轉(zhuǎn)向深水海洋領域。隨著越來越多的深水油氣開采設備投入使用，臍帶纜作為油氣開采設備必不可少的能源補給及信號傳輸?shù)募~帶，在油氣開采過程中起到了至關重要的作用。臍帶纜鋪設裝置是鋪設臍帶纜的專用設備，而深水臍帶纜鋪設技術被國外少數(shù)公司所壟斷，面對日趨激烈的海上油氣資源開采趨勢，研發(fā)一套具有自主知識產(chǎn)權的臍帶纜鋪設裝置顯的尤為重要。 本論文分析了深水臍帶纜鋪設裝置國內(nèi)外的發(fā)展現(xiàn)狀，通過對國內(nèi)外相關產(chǎn)品的調(diào)研分析及相關文獻資料的搜集，確定臍帶纜鋪設裝置的特點及應用范圍。查閱國內(nèi)外相關技術文獻，分析臍帶纜鋪設裝置作業(yè)環(huán)境下的風載荷及波浪載荷對裝置的影響，并根據(jù)國外相關產(chǎn)品技術參數(shù)，確定裝置作業(yè)時各工況下的受力情況。 根據(jù)臍帶纜鋪設裝置各作業(yè)工況下的邊界條件，對底座鎖緊機構及行走機構進行方案論證，確定最優(yōu)方案并對進行詳細結構及零部件的設計。重點對底座鎖緊機構壓緊卡爪、固定鉸鏈軸進行設計計算及理論校核。通過三維軟件UG進行模型的建立，并對結構進行運動干涉檢查分析確定結構設計的合理性。 通過有限元分析軟件ANSYS對底座鎖緊機構及行走機構的關鍵零部件進行強度及剛度的校核，確定結構的強度及剛度滿足要求。通過ANSYS拓撲優(yōu)化模塊對壓緊卡爪及壓緊塊進行優(yōu)化設計，確定結構的最優(yōu)方案。 對底座鎖緊機構建立運動學方程，通過MATLAB對底座鎖緊機構進行運動學仿真分析，驗證機構運動的可靠性。然后通過ADAMS再對其實際運動過程進行運動學及動力學仿真，對比運動學方程的仿真結果，確定仿真結果的正確性。 通過ADAMS對行走機構在推動機架運動及拖動機架運動工況下進行運動學仿真，得到合理的運動控制時間，使機架的運動速度滿足設計參數(shù)的要求。
[Abstract]:With the rapid development of the global economy, the demand for energy is increasing all over the world. In the face of the increasingly tight land resources, people are gradually turning their eyes to the deep-water ocean field. As more and more deep-water oil and gas extraction equipment is put into use, As the essential energy supply and signal transmission link of oil and gas exploitation equipment, umbilical cord cable plays an important role in the process of oil and gas exploitation. However, deep-water cord laying technology is monopolized by a few foreign companies. In the face of the increasingly fierce trend of offshore oil and gas exploitation, it is particularly important to develop a cord cable laying device with independent intellectual property rights. This paper analyzes the development of deep water cord laying device at home and abroad, through the research and analysis of related products at home and abroad and the collection of relevant documents. The characteristics and application range of cord cable laying device are determined. The influence of wind load and wave load on cord cable laying device under the working environment is analyzed by consulting the relevant technical documents at home and abroad, and according to the technical parameters of the related products abroad, the influence of wind load and wave load on the device is analyzed. Determine the working conditions of the device under various working conditions. According to the boundary conditions of the cord cable laying device under various working conditions, the scheme of the pedestal locking mechanism and the walking mechanism is demonstrated, the optimum scheme is determined and the detailed structure and parts design are carried out. The emphasis is on the pedestal locking mechanism compaction claw, The fixed hinge shaft is designed and calculated and the theory is checked. The model is built by UG, and the rationality of the structure design is determined by analyzing the motion interference of the structure. The strength and stiffness of the key parts of the pedestal locking mechanism and the walking mechanism are checked by the finite element analysis software ANSYS. The strength and stiffness of the structure are determined to meet the requirements. The optimal scheme of the structure is determined by optimizing the design of the compaction claw and compaction block through the ANSYS topology optimization module. The kinematics equation of the base locking mechanism is established, and the kinematics simulation analysis of the base locking mechanism is carried out by MATLAB to verify the reliability of the mechanism's motion. Then, the kinematics and dynamics simulation of the actual motion process is carried out through ADAMS. The correctness of the simulation results is confirmed by comparing the simulation results of kinematics equations. The kinematics simulation of the walking mechanism under the conditions of pushing the frame motion and driving the frame motion is carried out through ADAMS, and the reasonable motion control time is obtained, so that the motion speed of the frame can meet the requirements of the design parameters.
