The Control System Design of Asphalt Concrete Automatic Paver;

Based on the geodesic,a novel parallel equidistant path generation algorithm for composite fiber placement was implemented.

Based on the seven-degree-of-freedom fiber placement equipment independently developed,the fiber placement path planning for closed composite parts with core models is researched.

Based on composite cylinder structure with opening,the technology of two-step automated tape laying is explored and the parametric cylinder core model is set up.

According to the working principle of the automatic tape-laying machine,the paper analyzes the construction of automatic tape-laying machine,the drawing of the prepreg tape,the track programming of fiber placement on cylinder structure with opening and the dynamic display of the motion emphatically.

The performance requirements of the prepreg feeding system are analyzed for automatic tape-laying(ATL),and the importance of the prepreg precision feeding control technique in ATL processing is validated through kinematic and dynamic analysis,upon which a mathematic model for the prepreg feeding is designed.

The random changing of the tape length is analyzed in ATL processing based on the framework and the control system for the automatic tape-laying (ATL) numerical control equipment.

Automatic fiber placement is a sort of automatic manufacture technology which was raised first at the field of aeronautics and astronautics, and through it, the low-cost and high-quality advanced composite material can be produced.

Automatic fiber placement is one of the most important solutions to achievelow-cost and high-quality composite process.
