【摘要】：隨著計算機輔助設計技術的日益成熟,工程師越來越青睞使用其作為輔助手段對產品進行設計分析。它是通過人機配合的方式利用計算機軟件作為輔助工具進行設計的一種現(xiàn)代化設計方法,其優(yōu)點在于可以縮短產品設計生產周期,提高產品研發(fā)效率,節(jié)約材料,降低勞動及生產成本。尤其是參數(shù)化設計、有限元分析、剛體動力學分析、虛擬樣機技術與優(yōu)化設計等現(xiàn)代設計方法被廣泛應用于機械、航空等各領域�，F(xiàn)代游樂設備在滿足設計美觀的同時,也在朝著驚險刺激的方向發(fā)展,且運動形式復雜,安全性能要求較高。而在設計初始階段,由于設備運動及載荷形式復雜,動力學參數(shù)不完整,僅依據(jù)靜力學分析數(shù)據(jù)對其進行設計是不科學的,必須結合動力學分析獲取的動力學參數(shù)對其進行設計分析,以獲得最佳設計參數(shù)。本文以"自控飛機"游樂設備挑臂梁作為研究對象,利用SolidWorks軟件,根據(jù)設計要求,以國家標準及規(guī)范為依據(jù),綜合應用機械現(xiàn)代CAD技術,完成游樂設備挑臂梁的總體設計。主要研究內容如下:(1)在初始設計參數(shù)的基礎上,結合設計標準及安全要求,采用參數(shù)化設計方法建立該游樂設備的虛擬樣機模型,并通過SolidWorks-Motion的剛體動力學分析功能,獲得游樂設備在三種特殊工況下的零件間關鍵連接部位的時間-力的變化曲線,找出最危險工況及承受最大載荷的部位。(2)參照剛體動力學分析結果,得到挑臂梁關鍵部位承受的最大載荷,對挑臂梁進行結構設計,并利用SolidWorks-Simulation對挑臂梁進行靜力學分析,得到挑臂梁的應力、位移分布情況及安全系數(shù)。(3)以靜力學分析數(shù)據(jù)為參考依據(jù),通過對游樂設備挑臂梁進行優(yōu)化設計,在符合設計標準并保證安全的要求下,得到了挑臂梁的最佳設計參數(shù)。(4)將設計好的挑臂梁與其他零部件重新進行裝配后再次放回虛擬環(huán)境進行分析、對比和驗證,重新確定挑臂梁關鍵部位的時間-力的變化曲線。本文綜合采用參數(shù)化設計、虛擬樣機技術、有限元分析、動力學仿真等方法通過Simulation對挑臂梁進行了設計、優(yōu)化,在保證機械性能及安全性能的前提下,得到了最佳的結構參數(shù),證明該方法符合機械設計的一般規(guī)則及其可行性,探索了機械設計的CAD技術,為相似的游樂設備的設計生產提供數(shù)據(jù)參考和理論支持,并為相關產品的安全評估提供了一種新的思路和方法。
[Abstract]:As the computer-aided design technology is becoming more and more mature, the engineers are more and more interested in using it as an auxiliary tool to design and analyze the products. The method has the advantages that the product design production cycle can be shortened, the product development efficiency is improved, the material is saved, the labor and the production cost are reduced. In particular, the modern design methods such as parametric design, finite element analysis, rigid body dynamics analysis, virtual prototype technology and optimization design are widely used in various fields such as machinery, aviation and the like. The modern amusement equipment, while meeting the beauty of the design, also develops in the direction of the thrilling direction, and the motion form is complex and the safety performance requirement is high. In the initial stage of the design, because of the complexity of the equipment movement and the load form, the dynamic parameters are not complete, the design is not scientific according to the static analysis data, and the dynamic parameters obtained by the dynamic analysis must be designed and analyzed to obtain the best design parameters. Based on the design requirement and the national standard and the standard, the overall design of the arm beam of the amusement equipment is completed by using the software of SolidWorks, based on the national standard and the standard. The main research contents are as follows: (1) Based on the initial design parameters, the virtual prototype model of the amusement equipment is established by using the parametric design method in combination with the design standard and the safety requirements, and the dynamic analysis function of the rigid body through the SolidWorks-Motion is adopted. The time-force variation curve of the key connecting part between the parts under three special working conditions is obtained, and the most dangerous working condition and the part bearing the maximum load are found out. (2) With reference to the dynamic analysis of the rigid body, the maximum load of the key part of the cantilever beam is obtained, the structure design of the cantilever beam is carried out, and the static analysis of the cantilever beam is carried out by using the SolidWorks-Simulation to obtain the stress, the displacement distribution and the safety factor of the cantilever beam. (3) Based on the static analysis data, the optimum design parameters of the cantilever beam are obtained by the optimization design of the arm beam of the amusement equipment. (4) The designed cantilever beam and other parts are re-assembled and then put back to the virtual environment for analysis, comparison and verification, and the time-force variation curve of the key part of the cantilever beam is re-determined. In this paper, parametric design, virtual prototype technology, finite element analysis, dynamic simulation and other methods are adopted to design and optimize the cantilever beam, and the optimal structural parameters are obtained on the premise of ensuring the mechanical properties and the safety performance. It is proved that the method is in accordance with the general rules and the feasibility of the mechanical design, and the CAD technology of mechanical design is explored, which provides data reference and theoretical support for the design and production of the similar amusement equipment, and provides a new thinking and method for the safety evaluation of the related products.
