| Abstract: | In this paper,the basic rule on the forming of integral panel skin with grid-type ribs is discussed.Provided with the technique of realization,the data-base and the application range,five feature methods are discussed in detail,which are the straight method,the single characteristic method,the double characteristic method,the triple characteristic method and the two dots method.Using the program designed with the five methods,the solution of the characteristic relation of the stroke and the arc length in specific structure are obtained,based on it,the next quantity of the press and the value of the arc can be forecasted.Compared with the experiment data,it is shown that these methods of forecasting parameters are feasible. |
| Keywords: | integral panel skin with grid-type ribs self-adapting control incremental bending forming |
