Abstract

Additive manufacturing (AM) parts retain a certain degree of individuality and could suffer from a combination of different defect types, and is therefore the non-destructive evaluation on AM parts remains a challenging task. Engineering non-contact and non-destructive real-time inspection and in-situ quality assurance of AM parts would be a net improvement compared to current quality control methods that are conducted post-production. Here, the authors propose to combine the use of a laser vibrometer with a compression-driven shock tube to assess the quality of AM parts through the evaluation of the vibration spectra of the part. An AM of a cylindrical part was selected for the study, along with different defect types and sizes. These defects include internal voids of different sizes at different locations, local changes in thickness (infill), and local changes in melting temperatures. A numerical model was created and validated using experimental data to conduct model assisted probability of detection (MAPOD). Results were analyzed by evaluating correlation matrices between different models. Results showed that vibration spectra induced by a shock wave were sensitive to different types and sizes of defects under the studied geometry. The defect index yielded an approximately linear relationship with respect to defect void severity. MAPOD curve studies revealed a minimum detectable void defect 0.039% of the AM parts volume.

利用激光测振仪和激波管对增材制造进行实时无损评价
增材制造(AM)零件保留了一定程度的个性,并且可能遭受不同缺陷类型的组合,因此对增材制造零件的无损评估仍然是一项具有挑战性的任务。与目前后期生产的质量控制方法相比,增材制造零件的工程非接触和非破坏性实时检测和现场质量保证将是一个净改进。在这里,作者建议将激光测振仪与压缩驱动激波管结合使用,通过评估零件的振动谱来评估增材制造零件的质量。选择了一个圆柱形零件的增材制造,以及不同的缺陷类型和尺寸。这些缺陷包括不同位置的内部大小不同的空洞,局部厚度(填充)的变化,以及局部熔化温度的变化。建立了数值模型,并利用实验数据对模型辅助检测概率(MAPOD)进行了验证。通过评价不同模型之间的相关矩阵对结果进行分析。结果表明,在所研究的几何形状下,激波引起的振动谱对不同类型和尺寸的缺陷都很敏感。缺陷指数与缺陷空洞严重程度呈近似线性关系。mapapod曲线研究显示,最小可检测的空洞缺陷为AM零件体积的0.039%。
