摘　　要：采用基于Lab VIEW的悬臂梁自由振动衰减实验研究了轻质玻纤增强热塑性复合材料(GMT)的密度及悬臂梁长度对其阻尼比、固有频率及动弹性模量的影响。实验结果表明,GMT的阻尼比和固有频率随GMT材料密度、悬臂梁长度的减小而增加,动弹性模量随GMT材料密度、悬臂梁长度的减小而减小。The influence of lightweight glass fiber reinforced thermoplastic composite（GMT）’s density and cantilever length on its damping ratio,frequency and dynamic elastic modulus through the free vibration of cantilever beams based on LabVIEW were studied. The experimental results show that the damping ratio and frequency of GMT increase with the decrease of GMT’s density and cantilever length. While the dynamic elastic modulus of GMT decrease with the decrease of GMT’s density and cantilever length.
