Simulation And Optimization Of Automatic Routing On Cable Networks On Missiles

Nowadays strategic competitions between countries are increasingly intense. The serious situations of domestic and international put forward higher requirements to our national defense ability construction. The future war will presents such characteristics as space against, system against, and non-contact confrontation. It is an essential elements that weapons and equipments become flexible and response rapidly on the future battlefield. So the missile weapons tend to be functional, high integration, overall light-duty and miniaturization. These directions lead to missiles’ structure and cable networks present a trend of integration and complexity development, and also increase the difficulty of design and manufacture on cable networks. Meanwhile, with the development of missile weapon system, the states of development a new type of missiles convert frequently. Development cycles are shortened as a consequence. Hence, cable networks on missiles are faced with unprecedented challenges in many aspects such as design, manufacture and assembly.Cable network system on Missiles is the "nerves and blood vessels", which secures in electricity and electrical signal transmission. In the entire realization of functions, cabling system plays a crucial role on the missiles. That is to say, to a great extent, the quality of the cable network affects the quality of the product. However, the pattern of design, manufacture and assembly of cable net we used is still relatively backward which is serial design based on module test. At the beginning of the design is given more priority to meet the functions, the consideration of overall structure of the cable net is not comprehensive. Its appearance structure parameters modify mainly depends on the mold filling process of the test samples. This serial pattern hardly conform to the trend that integral design faced with manufacturing and assembly, lead to a lack of rationality and practicability of the cable net. At the same time, serial design mode virtually increased the development cycle and cost of missiles, which cannot meets the demand of today’s missile manufacturing.Aimed at developing types of missiles, problems of cable networks arising from the design, manufacture, assembly process, this paper studies the technology of automatic routing based on the three-dimension virtual model, discusses model creation method of cable networks. By using cubic B spline curve, flexible cable net model is constructed. Then grid maze algorithm is studied for automatic cable wiring, by which the routing process would be optimized. Using the inverse movement kinematics modeling method for cable network, the simulation of routing results is realized. Besides, the research theory is applied to production process and is verified by practical instances.This paper’s mainly content is as follows:1, studies the whole machine cable net routing technique, cable 3D modeling method and the content of the information model is discussed; analysis the cable laying principles and characteristics, and the technique is applied on a certain type of electronic tank section of a missile.2, studies the whole machine cable network automatic routing technology, discusses the pretreatment method of laying space model, divide equipped space into 3 level mesh, through the establishment of a global coordinate system to realize the path selection, constraint models of cable routing rules are discussed, using the maze algorithm to automatic routing cable networks on missiles.3, researches the rigid-soft-mixed assembly simulation technology, discusses the deficiency of existing assembly process, based on the situation that separated simulate rigid and flexible parts, this paper studied the simulation processes and methods of rigid-soft-mixed assembly, developed a planning of rigid-soft-mixed assembly simulation method. And the result of the electronic routing module is simulated, by which studied the realization process.
