Abstract：The key components of large composites fiber placement machine are calculated and analyzed. The overall structure of mesh and load constraints of fiber placement machine are introduced. The deformation and the deformation of linear motion accuracy are caused by the weight of the fiber placement machine when the beams and fiber placement head are in a different working position. Analysis of data on key components of fiber placement machine provides a theoretical basis for structural optimization, in particular, anti-deformation of beam design provides important data.
