As a new composite material , the application of the aircraft structure since the 1970s has only about 40 years of history, is in the growing phase. The combination of carbon fiber and resin composite material , because of its small specific gravity , toughness , and strength to become an advanced aerospace materials . The main subject of the traditional wing weight of large defects in light aircraft wing as the research object , the choice of carbon fiber as a reinforcing material in the original laminate theory , based on the development of new composite wing placement manufacturing equipment - wing placement machine and motion simulation and finite element analysis of key components for industrial applications to provide the necessary basis. This paper designs gantry placement machine to laying the wing . Placement machine including gantry gantry base , motion transmission mechanism , placement head , four wing mandrel fixture parts, including placement head rotation , the rotation of the core mold clamping mechanism , the vertical and horizontal placement head move 4 freedom of movement . Where placement head is the design part of the most important institutions , including the feeding device , measuring devices , ultrasonic cutting devices, heating boxes, laying roller , rolling devices and assistive devices such as guide . Wing core mold clamping mechanism comprises a head and tailstock, the main achievement of the mandrel along its axis of rotation . Gantry placement machine compact design is more reasonable , laying angle adjustment is easier to implement , a smaller footprint . The design process to Pro / E as a platform for the entire laying equipment to establish a complete three-dimensional model . Meanwhile , the use of Pro / E, Pro / Mechanism module gantry placement machine to make the process of laying the wing motion simulation , so that the whole exercise process more intuitive, guiding the production process of great help. This paper uses the powerful ANSYS finite element analysis capabilities , select the gantry placement machine supports the entire placement trolley traversing the transverse slide plate finite element analysis , theoretical calculations and the actual results are compared to prove the feasibility and reliability of design sex .
