为准确获取带控制系统全尺寸栅格舵的静、动态铰链力矩数据,分析舵控系统性能,需要研制强度、刚度、灵敏度及抗电磁干扰能力均符合试验要求的风洞侧壁支撑天平。栅格舵法向力大,铰链力矩小,且试验平台限制了天平结构的长度,导致天平在载荷匹配与元件布置方面有较大难度。通过有限元分析技术优化天平结构,在适量放大铰链力矩载荷设计指标的基础上,采用法兰盘代替传统的锥连接,天平各元件串联布局等手段,成功研制出了满足试验要求的天平。试验结果显示,模型静、动态试验数据规律良好,天平的动态响应能力及对小量铰链力矩的测量满足试验需求。
In order to obtain the static and dynamic hinge moment data of the full-scale rudder with control system and analyze the performance of the rudder control system, it is necessary to develop a wind wall sidewall support balance that meets the test requirements in strength, stiffness, sensitivity and electromagnetic interference resistance. Rudder rudder normal force, hinge moment is small, and the test platform limits the length of the balance structure, resulting in the balance in the load matching and component layout more difficult. Based on the finite element analysis (FEM) optimization of the balance structure, an appropriate amount of magnifying hinge torque load design index was adopted, and the flange was used to replace the traditional cone connection and balance element layout in series. The balance for the test was successfully developed. The experimental results show that the static and dynamic model data of the model have a good regularity, the dynamic response capability of the balance and the measurement of a small amount of hinge moment satisfy the test requirements.
