Abstract
The multi-body dynamics model of a multiple missile launcher was built, and its vibration characteristics were studied from three aspects of theory calculation, simulation calculation and test; vibration modes were computed and analyzed. The results show that the natural frequency of launching system is about 3~20 Hz, which can also provide an important reference to modal testing and dynamic response analyzing of the whole vehicular missile oblique launching system. As the absolute value of the maximum relative error between results of simulation and test is less than 10%, the calculation results agree well with modal testing results, verifying the correctness of the modeling and analyzing method.
