新型应变天平校准系统自动加载装置研究

摘要

Considering the characteristics of the wind tunnel balance calibration system,the automatic weight loading is the most important part.The clamping modules are the first time to be used as the lifting device in the weight mechanism design for the strain gauge balance calibration system,with them the structure of weight loading mechanism is greatly simplified.%风洞应变天平是风洞测力实验中最关键测量装置。为实现风洞应变天平校准系统的砝码自动加载，通过分析对比现有砝码自动加载方式的优缺点，结合应变天平校准系统特点，设计并研制采用膜片式夹紧气缸作为砝码升降机构执行元件的砝码加载装置。加载装置具有结构简单、体积小巧、性能稳定等优点。
