Abstract

The missile launching system is a typical complex mechanical system, which is becoming increasingly larger in scale and more complicated in structure. Designing these types of products often requires repeated complex and time-consuming model design, calculation, and analysis of the dynamics of the system. The most time-consuming is repeatedly modifying the geometric and dynamics models. In this article, we put forward a new method for bidirectional-driving parameter between CAD and CAE, by changing the geometric model parameters, which directly changes the dynamics model. A parameterized multibody system dynamics modeling and analysis software for missile launching system are proposed, which gathered modeling, solving, visual simulation as a whole, and realized design parameters seamless transfer between geometric models and dynamics models for missile launching system. In order to examine the correctness of the simulation results, a parameterized experimental platform for missile launching system is designed, which can modify the key parameters as designed in simulation software. Finally, a missile launching system simulation and test examples are given, and the simulation analysis and experiment results demonstrate that the overall trend of the simulation results of multi-rigid and rigid-flexible coupling dynamics model is consistent with the experiment results.
