为保证风洞试验设备的安全,吹风对象固定机构的强度和刚度要满足要求。利用CATIA建立某无人直升机风洞吹风试验固定机构的三维模型,基于ANSYS软件模拟该无人直升机吹风试验的典型工况,得到固定机构在典型工况下的应力和变形值,确定固定机构的设计方案。这种CAD/CAE一体化的设计,能较大提高设计效率,为其他结构设计提供借鉴。该固定机构已经安全应用于某无人直升机的吹风试验。
In order to ensure the safety of the wind tunnel test equipment, the strength and rigidity of the fixed body of the blowing object should meet the requirements. Using CATIA to establish a three-dimensional model of the unmanned helicopter wind tunnel blowing test fixture, based on ANSYS software to simulate the typical conditions of the unmanned helicopter blowing test, the stress and deformation values of the fixed mechanism under typical conditions were obtained, Design. This CAD / CAE integrated design, can greatly improve the design efficiency, provide reference for other structural design. The fixing mechanism has been safely applied to the blowing test of an unmanned helicopter.
