| Abstract: | To meet the requirement for testing composite materials with complex surfaces in the aerospace field,this paper designs a 5-axis testing device.The kinematical equation of the model is deduced in the Denavit-Hartenberg (D-H) method.Then,the coordinates and normal vector information of discrete points on the surface of the object are obtained by use of Rhino software.Finally,amounts of movement of the joints of the inspection device are controlled through inverse solution of kinematical equation to realize scanning of complex surfaces. |
