The Temperature Finite Element Analysis of An Unmanned Helicopter's Blades of Composite Moulds in the Curing Process

对某无人直升机桨叶铝制模具进行三维瞬态温度场的数值模拟,预测出桨叶固化过程中模具型腔的应力随温度的变化,为评估模具设计方案、优化桨叶固化工艺参数提供理论依据;比较数值仿真的温度值和传感器测得的温度值,两者相差较小,从而证明数值模拟的精度和有效性。

Work out the stiffness and intension of an UAV's tail vane based on the finite element analysis software ANSYS. The numerical values of the stiffness and intension tally with the result of the ballast experiment. Do optimization design of the tail vane based on the result of the test and analysis, then analyse the new model by FEA. The result show that the improved models could satisfy the use requirement.
