摘要
减摇鳍的执行机构是减摇鳍装置完成收放及减摇功能的核心部件,也是鳍翼面升力与阻力的主要传力部件.采用Patran/Nastran对某收放式减摇鳍执行机构进行三维非线性接触有限元计算,确定其应力应变场,为其优化及改进提供设计依据.
The retractable fin stabilizer＇s actuating mechanism is the core of its system,which aims to enable the fin devices to be retractable and to pass the lift and the resistance from the fin＇s wings to the hull in working.In this paper,MSC/Nastran is used to conduct three-dimensional nonlinear contact finite element calculations for a certain retractable fin actuator structure,in order to determine the stress and strain fields,and provide the analytical foundation for all systems＇ optimization and improvement.
