Abstract:In this paper,we make a research on mesh post disposal of composite winding and robot motion control theory and establish an offline wind programming and simulation platform of an industrial robot based on Matlab and ADAMS It can do CAD of winding path according to equal distance,equal height and equal fiber length three different envelop forms, and generate the executable file on the robot automatically At the same time, it can optimize the winding path by doing animation simulation and motion analysis of the winding process Simulation and physical experiments of winding one bent pipe have been done It shows that the platform is reliable and practical, winding path design is convenient and accurate and the simulation effect is ideal Simulated experiment can effectively shorten robot winding path development, cut down the times of physical experiments and save the development costs
Keywords:robotic winding; offline programming; computer emulation; mesh post disposal
