Abstract
Research on Parametric Modeling Optimization of Trajectory Correction Projectile Based on FVM
Highlights
Intelligent ammunition, with its precise strike capability, plays an increasingly important role in the modern local wars [1]
The solution of fluid computer based on N-S equations is the core of Computational Fluid Dynamics (CFD), and Finite Volume Method (FVM) is the computational method of the main stream of fluid
For the fluid aerodynamic simulation computation, the grid section is popular hexahedral meshing method, the meshing time of some complex models tends to account for about 90% of total amount control
Summary
Intelligent ammunition, with its precise strike capability, plays an increasingly important role in the modern local wars [1]. The simulation computation of the local modification scheme, a lot of design time was used to carry out repeated modeling and meshing [6]. Parametric design provides a new concept for ammunition design that can save the modeling process of intelligent ammunition, reduce the complexity of repeated work and greatly drop off the design cycle. As the commercialization of fluid computing software becomes more sophisticated, parametric modeling functions in software development have been integrated by software vendors and are greatly improving the performance of the use of software. Combining parametric design ideas and parametric + script generation functions, it can greatly improve the design efficiency of intelligent ammunition and provide a good design basis for the aerodynamic analysis of CFD. This article focuses on parametric design analysis of mesh module
