The Kane-Huston method was used to establish a general launching dynamics model of a multi-tube rocket. The modeling problems of the elasticity of the directional tube and the tube-tube friction were mainly studied. The concept of constraint matrix is proposed to facilitate the automatic completion of constraint processing and the reduction of system dynamics equations. The launching process of a multi-barrel rocket was analyzed and calculated, indicating the correctness and feasibility of the model and the corresponding software
