Researchs On Land-based Mobile Missiles Moving Alignment

The land-based missiles play an important role in tactics and strategy. It is particularly important to improve alignment accuracy before launching, to simplify the alignment process.It become a very important job in the deployment of strategic and tactical. wherefore, regard to the characteristics of land-based motor missiles, In connection with the vary motor ways, we need to design different plans of alignment.In order to carry out land-based mobile missile initial alignment study in this paper. The main work includes in this paper as below:First of all, the domestic and overseas research of Land-based missiles, initial alignment technology. On this basis, we propose to apply land-based missile launch rapid initial alignment of research programs.Secondly, define the common coordinate syst em and its transformation for land-based missiles. Also, the attitude singularity problem is solved by expand the ranges of angles. Based on the dynamic theories, the mathematical model and its linear control model are established in detail, which is the f oundation of the follow-up studies and simulations. According to the strapdown solution solver principle, derived land-based missiles initial alignment and calculation model.Then, depending on the the motorized sports to design proper alignment program. A missile launch process can be divided into: the trave road alignment model and the alignment erected for launch aligned model. Incentive travel between aligned in accordance with the model divided into: acceleration and deceleration incentive Moving Base Transfer Alignment and posture excitation transfer alignment. Erected for launch Alignment to consider wind interference and lever arm compensation. Comprehensive before alignment program, design a reasonable alignment of multi-mode convergence program.Finally, according to the initial alignment of the program, one by one mathematical simulation and physical tests, analysis of the feasibility and accuracy of the program. The results of initial alignment error analysis. First, the analysis accuracy of the model; then, analytical errors inertial device; Lastly, accelerometer immeasurability proposed secondary alignment scheme, the estimated level of accelerometer drift, thereby to improve the alignment accuracy.
