Abstract

Abstract: System design method of firing precision for multiple rocket launchers is the key technology to get high firing precision of multiple rocket launch system (MLRS). In order to solve the long exist difficult problem which restrain the development of MLRS for lack of system design method of firing precision, it starts with describing the MLRS dynamics style quickly and accurately, a visual simulation and design software of MLRS dynamics and firing precision database of MLRS is built by introducing a new method for multibody system like transfer matrix method for multibody system and combining modern computer technology through 20 years of continuous deep study in three aspects of theory, computation and experiment. Accordingly, the first weapon industry standard and national military standard of system design method of firing precision for multiple rocket launchers are formulated. These include design principles and condition and process of firing precision for MLRS, model design, dynamics simulation and optimization, virtual prototype design program and its virtual test results, experimental verification of virtual test, multiple rocket launcher firing precision system design. Above all provide a theoretical basis and technical means and technical standards for system design method of firing precision for multiple rocket launchers. And an example for the dynamic design of other weapon systems and other mechanical systems is provided. Some practical examples are given that use the proposal method in the design of firing precision for MLRS in the fields of weapon, shipping, aviation and aerospace industries of our country to improve significantly the design level of firing precision for multiple rocket launcher and the firing precision for MLRS.
