摘要：
The dynamic analysis of rocket sled test system was carried out, and the calculation method of rocket sled motion was studied. Based on the conventional algorithm, the calculation method of some parameter was improved, and a new parameter energy dissipation resistance was introduced to obtain the optimization algorithm. Comparing the results of four double-track sled tests with different speeds with the calculation results of the conventional algorithm and the optimized algorithm, it was found that: the minimum error of the conventional algorithm calculation result was 7.67%, the maximum error was 37.91%, and the minimum error of the optimized algorithm calculation result was 0.48%, and the maximum error was 5.0%; comparing the results of four different speed monorail sled tests with the calculation results of the conventional algorithm and the optimized algorithm, it was found that: the minimum error of the conventional algorithm calculation result was 11.78%, and the maximum error was 43.64%, and the calculation result of the optimized algorithm had a minimum error of 0.11% and a maximum error of 5.31%. The results showed that the optimization algorithm of rocket sled calculation can effectively improve the accuracy of calculation results compared with conventional algorithms, and the calculation results have certain engineering guiding significance for rocket sled test design. © 2021, Editorial Department of Journal of Aerospace Power.
