Research On Lightweight Analysis And Forming Equipment Of Airborne Chassis

Carbon fiber composites have been rapidly developed due to their light weight,high specific strength and specific stiffness.They have been combined with metal materials,inorganic non-metallic materials and polymer materials to become four materials.Advanced composite materials,especially carbon fiber polymer matrix composites,are lightweight and high strength properties and are ideal lightweight materials.Based on the goal of lightweight,research on structural optimization,molding process and special molding equipment for carbon fiber reinforced composite components is one of the hot topics in aviation today.The lightweight of aeronautical components is of great significance for the energy conservation of aircraft components such as aircraft,the reduction of inertial force,high-speed flight,and the adaptation of air attitude changes.One of the goals of space technology development in the 21 st century is to reduce the mass of the spacecraft and reduce the size of the spacecraft,and to make deep technical breakthroughs in terms of lightweight and miniaturization.There are many types of aviation components,and it is necessary to do a lot of research work to fully realize the weight reduction.The main research contents of this subject include two parts:(1)lightweight research on carbon fiber reinforced plastic aviation chassis;(2)design and mechanical performance analysis of aerospace chassis molding equipment.Carbon fiber reinforced plastic aviation chassis lightweight research.Taking the aviation instrument box as the research object,based on static analysis,the structural properties of carbon fiber reinforced plastics and aluminum alloys are compared and compared,and the optimal wall thickness of the box is optimized by simulating the orthogonal structure to simulate the optimal wall thickness of the box.Excellent lightweight structural parameters.Design and mechanical performance analysis of aerospace chassis forming equipment.Based on the research on the structure of the aircraft instrument and the forming method of the dipping and extrusion,a set of aeronautical instrument box molding equipment was designed.The three-dimensional model of the forming equipment was established,and the static analysis of the forming equipment was carried out.The finite element simulation results show that the stress and deformation of the forming equipment meet the requirements of working strength and rigidity.Finally,the UG motion simulation of the molding equipment is carried out,the actual movement of the molding equipment is simulated,the motion law and assembly relationship of the molding equipment are analyzed,and finally the equipment model is improved and further optimized according to the obtained data.
