翼伞组提带张力传感器的有限元分析

Finite Element Analysis on Tension Sensor of Lifting Belt of Parafoil Strap

翼伞在民用、军事、航空领域有广泛的应用,尤其在新冠疫情爆发期间,翼伞在物资投放中发挥了重要的作用。翼伞的组提带张力对其飞行的安全性以及着陆地点的精确性至关重要。为实现翼伞组提带张力的测量,设计一种工字型无线张力传感器结构,可解决现有张力传感器存在的量程不足、会破坏组提带结构等问题。运用SolidWorks设计弹性装配体模型并导入ANSYS Workbench18.0,对其进行静力学分析,选取传感器材料并找到应变片最佳的粘贴位置,对该传感器模型进行静力学仿真和模态分析,分析结果证明该传感器结构的可行性。

Parafoil,widely used in civil,military and aviation fields,especially during the outbreak of new coronal epidemic,plays an important role in material delivery.As the tension of lifting belt is very important for the safety of parafoil flight and accuracy of landing site,an I-shaped wireless tension sensor structure is designed to measure the tension of parachute which can solve the problems like insufficient range of existing tension sensor and damage of lifting belt structure,etc.The elastic assembly model is designed by SolidWorks and imported into ANSYS Workbench 18.0 for static analysis.The sensor material is selected and the best sticking position of strain gauge is located for the static simulation and modal analysis of the sensor model,with the results proving that the improved sensor structure is feasible.
