Compared with the traditional full housing model, a calculation method model is a plate beam unit model, the geometric nonlinearity and contact problem solution which is large in time consumption and difficult to converge is replaced by the linear solution, and accordingly the modeling time consumption is small, the calculation speed is high, and the requirements for the professional quality of the computer hardware and analysis staff are low.

The invention relates to a curved surface cutting trajectory obtaining method based on an STL model. The method comprises the steps that (1) all cut surface coordinate sets are determined according to the highest point and the lowest point of the model; (2) a cut surface is positioned, wherein triangular patch coordinates are used for positioning the index value of the corresponding cut surface in the coordinate set according to a hash function, and cut surface coordinates with an intersection point are obtained through the index value; (3) the intersection points of the cut surface and triangular patches are calculated to obtain section lines; (4) the section lines are ranked to obtain a cutting trajectory. According to the curved surface cutting trajectory obtaining method, in the layering process, each triangular patch is only visited once, and no complex topology structure needs to be built for the read triangular patches. After offset is conducted on the obtained curved surface cutting trajectory, the curved surface cutting trajectory can be used for generating a numerical control ring cutting machining tool path.
