摘要
仿生学作为一门传统学科,其理念已广泛应用于汽车及航空外形结构设计,在整车设计中,仿生结构的运用通常是为了减少风阻,降低汽车油耗以达到节约成本的作用。通过在传统汽车尾部添加具有仿生结构的扰流板和非光滑棱纹并对其进行CFD仿真实验,分别从空气流量分配、最大压力变化和汽车升/阻系数三方面验证了具有仿生结构的汽车与传统汽车相比具有良好的减阻增稳效果。
Considering there are many disadvantages existing in the common fatigue loading test systems such as rotating fatigue loading system and hydraulic fatigue loading system, this paper designs a new kind of electromagnetic pulse fatigue loading system for wind turbine blades. Related parameters are calculated and the feasibility analysis of the system design is presented. Electromagnetic pulse fatigue loading system has the advantages of simple equipment, controllable, low mass.
