【摘要】：電纜在汽車、船舶、飛機等復雜機電產品中占有舉足輕重的地位,特別是隨著復雜機電產品向著信息化、輕量化和機電一體化的發(fā)展,電纜所占比重越來越大。無論是傳統(tǒng)的串行設計方法還是現行的CAD方法,目前機電產品中電纜的設計、制造及其裝配主要存在因將電纜作為剛性體而導致的設計精度差和無法驗證裝配工藝等方面的問題。虛擬裝配技術的出現為電纜的數字化設計與制造帶來了一種全新的思路。本文主要開展基于彈性桿非線性力學的電纜物性建模及電纜形態(tài)仿真研究,為開發(fā)完善的電纜虛擬裝配系統(tǒng)奠定良好的基礎。論文的研究工作主要包括以下幾個方面：(1)從微分幾何角度出發(fā),在分析曲線和曲桿的幾何學基礎上,基于彈性桿非線性力學建立了描述電纜平衡的基本靜力學模型；(2)針對理想狀況下電纜兩端約束這一典型邊界條件,以歐拉角為參變量,建立了描述電纜形態(tài)的力學模型,基于動力學比擬的思想并采用半解析法對模型進行求解；(3)考慮電纜分布力及接觸力接觸復雜約束下,以歐拉參數為參變量,建立了描述電纜形態(tài)的力學模型,結合逐級二分離散化的思想和最速下降法對模型進行數值求解；從變分原理出發(fā),考慮電纜所受不同的幾何約束,建立了描述電纜平衡形態(tài)的統(tǒng)一力學模型,使之能夠方便地應用于電纜的虛擬裝配系統(tǒng)；(4)基于開源幾何內核系統(tǒng),對不同邊界條件下的電纜進行形態(tài)仿真；基于三維激光掃描技術建立了電纜形態(tài)測試試驗臺,開展了電纜典型平衡形態(tài)的仿真與試驗對比研究；(5)開展了基于一款氣動力反饋數據手套和一款桌面式七自由度力反饋器的人機交互研究,進行了力反饋設備與虛擬環(huán)境中剛性體之間的力觸覺交互驗證。
[Abstract]:Cable plays an important role in complex mechanical and electrical products such as automobile, ship, aircraft and so on. Especially with the development of complex electromechanical products to information, lightweight and mechatronics, the proportion of cable is more and more important. Whether it is the traditional serial design method or the current CAD method, the design of the cable in the mechanical and electrical products is at present. The fabrication and assembly are mainly caused by the poor design precision and the inability to verify the assembly process caused by the cable as a rigid body. The appearance of virtual assembly technology brings a new idea for the digital design and manufacture of cable. This paper mainly develops the cable physical modeling and cable based on the nonlinear mechanics of elastic rod. The study of morphological simulation lays a good foundation for the development of a perfect cable virtual assembly system. The research work of this paper mainly includes the following aspects: (1) from the point of differential geometry, based on the geometry of curve and curved rod, the basic statics model of cable balance is established based on the nonlinear mechanics of elastic rod. 2) in view of the typical boundary conditions under the ideal condition of the cable, the mechanical model describing the cable form is established with the Euler angle as the parameter. Based on the idea of dynamic analogy and the semi analytical method, the model is solved. (3) considering the complex constraints of the cable distribution force and contact force contact, the Euler parameters are considered as the parameters. The mechanical model describing the cable form is established, and the model is solved numerically with the idea of two separation and dispersion and the method of the fastest descent. Based on the variational principle, considering the different geometric constraints of the cable, a unified mechanical model is established to describe the cable balance form, so that it can be conveniently applied to the virtual assembly system of the cable. (4) based on the open source geometry kernel system, the cable is simulated under different boundary conditions. Based on the three-dimensional laser scanning technology, the cable form test test rig is set up, and the simulation and test comparison of the typical cable balance form is carried out. (5) a pneumatic feedback data glove and a desktop seven self are carried out. The interaction between force feedback device and rigid body in virtual environment is verified by human-machine interaction.
