The finite element dynamics simulation and modal test for monorail rocket sled. Firstly, the finite element model of the monorail rocket sled is established and the modal simulation analysis is carried out, and its natural frequency and modal mode shape within 400 Hz are obtained. Secondly, a monorail rocket sled modal test model is established, and the modal test analysis of the free-state monorail rocket sled structure is carried out by hammering method, and the natural frequency within 400 Hz of the monorail rocket sled structure and its corresponding modal mode shape are obtained. Finally, the test results and finite element simulation results are compared and analyzed in detail. The results show that the natural frequency error of the two is less than 15%, and the experimental mode shape is consistent with the finite element simulation mode shape, which proves that the simulation analysis results are true and reliable.
