摘要
在调查温室所处地区风速分布的基础上 ,研究风载与天窗位置角及风向的关系 ,以及风载、均布结构重量和集中力 3种天窗荷载的作用。建立多目标非线性优化模型 ,合理快捷地确定了气动天窗机构的各个参数 ,给出优化后气缸负载的动态曲线。
The pneumatic mechanism of ventilation-windows is a new operation type of ventilation-windows and has a series of advantages over other types of ventilation-window system, in which the ventilation area is greatly increased and the environmental conditions through ventilation are remarkably improved. Through observing the distribution of wind speed in East-China, a new method was adopted to study the relations among wind load, ventilation-windows and then a multi-objective, nonlinear optimization model was developed to determine the parameters of the pneumatic ventilation-windows mechanism.
