摘要

采用试验研究与有限元模拟相结合的方法，对钛合金宽弦空心风扇叶片冷却方式对残余应力的影响进行研究。在不同换热条件下，采集了TC4钛合金方板温度数据，并使用DEFORM软件反求解不同条件下的界面换热系数。进行了高温单轴拉伸试验，通过对不同冷却方式下的残余应力进行对比，验证了有限元模拟的准确性。对空心风扇叶片无应力状态的温度场及应力场进行了分析，并对比了两种冷却方式对零件残余应力的影响。研究发现，冷却后的残余应力主要分布在叶片内部空心部分及叶身薄壁边缘处。此外，在空冷冷却过程中，残余应力值冷却开始时迅速达到峰值，然后冷却过程逐渐松弛下来。相比之下，随炉冷却时外界温度下降较慢，不会在冷却初期生成应力峰值。以上研究结果可为TC4钛合金宽弦空心风扇叶片的批量化制造生产提供指导性意见。

Abstract

This study investigates the influence of cooling methods on residual stresses in wide-chord hollow fan blades made of titanium alloy through a combination of experimental research and finite element simulation. Temperature data from TC4 titanium alloy square plates under various heat transfer conditions were collected

and the interfacial heat transfer coefficient under different conditions was determined using the DEFORM software. High-temperature uniaxial tensile tests were conducted

and the accuracy of the finite element simulation was verified by comparing residual stresses under different cooling methods. The temperature and stress fields of the stress-free state for hollow fan blades were analyzed

and the effects of the two cooling methods on the residual stresses in the component were compared. It was found that residual stresses after cooling primarily distributed within the hollow section of the blade and along the thin-walled edges of the blade body. Furthermore

during air cooling

residual stress values rapidly peaked at the onset of cooling before gradually relaxing throughout the process. In contrast

furnace cooling

with its slower external temperature decrease

did not generate stress peaks during the initial cooling phase. These findings provide guiding principles for the mass production of wide-chord hollow fan blades made from TC4 titanium alloy.
