Study of optimization platform for ocean engineering riser based on grid
摘要
Abstract
Risers are widely used in many ocean engineering structures, but many serious disastrous owning to vortex-induced vibration of riser make it an urgent task to do further research in reducing destroy. Because of large-quantity computation requirements and complex controls in finishing the optimization, it is necessary to construct a computation platform of the optimization for the flexible system. According to the requirements of ocean engineering optimization, a hierarchical structure of grid cluster was proposed, and a triangle attached object was set before the circular cylinder to reduce the vortex-induced vibration destroy. The complex work was completed in collaboration way based on grid efficiently, and the optimization results also disclose that lift coefficients can be drop a lot.关键词
