Dynamics Analysis for Wheeled and Tracked Multiple Launch Rocket System

doi:10.3969/j.issn.1000-1093.2012.11.002

Abstract

Abstract: The launch dynamics characteristics of tracked multiple launch rocket system (MLRS) were studied and compared with the dynamics characteristics of wheeled MLRS, and a method to improve firing dispersion was proposed. The launch dynamics model, vibration characteristics, dynamics response analysis and simulation system of a tracked MLRS were developed by using the transfer matrix method of multi-body system and launch dynamics theory. The simulation results of vibration characteristics were validated experimentally. The vibration characteristics, dynamics response, rocket initial disturbance and firing dispersion of wheeled and tracked MLRS were compared and analyzed. The analysis results show that there are some differences among them. The dynamics characteristics of tracked MLRS are better than that of wheeled one.
