| Abstract: | The method for estimating the parameters of dynamic mathematical models for non-linear powder bodies and the computer program,H-16,based on this method were developed.The satisfactory results were got by processing the data of hot pressing experiment of atomized iron powder with the H-16.The way of accelerating iteration process was discussed also.By improving Simpson's algorithm,for variable step length,integral operation may increase in speed by one to dozens of times. |
