| Abstract: | The paper introduces parallel algorithm for distributed dynamic load identification calculation,to improve the serial algorithm problem of the high time-consuming and insufficient memory t for large-scale mathematical calculations. Based on the theory of one-dimension distributed dynamic identification,the CUDA parallel program of the dynamic load identification is developed. Example proves accuracy and efficiency of the parallel algorithm. The paper provides a new idea to improve the efficiency of the dynamic load identification. |
