摘要
对机翼风洞模型进行静强度试验,可以防止模型在风洞试验时发生破坏造成巨大经济损失。基于机翼模型大变形特征设计了一种新型随动加载装置,采用载荷-位移协同控制方法进行精准加载,保证模型发生大变形时翼面加载点受力方向始终垂直于模型表面,通过机构-结构联合仿真和相关试验对加载单元原理与控制方法进行了验证。结果表明,该加载单元原理正确,控制方法能够满足加载载荷的准确性、稳定性和方向的跟随性,高效可行,为机翼风洞模型的静强度试验提供了一套合理可行的方法。
The static strength test of the wing wind tunnel model can prevent the damage of the model during the wind tunnel test from causing huge economic losses.Based on the large deformation characteristics of the wing model,a new type of follow-up loading device is designed.The load-displacement collaborative control method is used to accurately load,ensuring that the force direction of the loading point on the wing surface is always perpendicular to the model surface when the model had large deformation.The principle and control method of the loading element are verified by the mechanism-structure joint simulation and related tests.The results show that the principle of the loading element is correct,and the control method can meet the accuracy,stability and direction of the loading load,which is efficient and feasible.It provides a reasonable and feasible method for the static strength test of the wing wind tunnel model.
