[交流] 动态力学分析仪工作原理

Dynamic mechanical analysis (DMA) is an analytical technique which measures the modulus (stiffness) and damping (energy dissipation) properties of materials as those materials are deformed under periodic (oscillatory) stress. There are several components which are critical to the design and resultant performance of a dynamic mechanical analyzer. These components are the drive motor (which supplies the sinusoidal deformation force to the sample material), the drive shaft support and guidance system (which transfers the force from the drive motor to the clamps which hold the sample), the dis- placement sensor (which measures the sample deformation [oscillation amplitude] that occurs under the applied force), the temperature control system (furnace), and the sample clamps.
