双高速数字成像系统，用于在撞击过程中以高达4,000帧每秒的帧速率获取的两个同时的、高分辨率的可变形物体的数字图像。图像的分辨率和质量将使机械变形和应变得以量化。然后，这些运动学信息将被用于分析承受外部冲击力的车身内部的应力。循环载荷下材料的胡萝卜数据将用于间接确定与频率和幅度相关的材料常数。受生物启发的结构在瞬时载荷作用下的变形将被用来评估它们的机械阻力和强度。通过使用内窥镜探头，将获得人类喉部的图像，以便量化人类声带在不同发音类型和水平时的机械应力。这将有助于评估冲击应力及其与组织损伤的相关性。

Dual high speed digital imaging system for the creation of two simultaneous, highly resolved digital images of deformable bodies during impact at high velocities acquired at frame rates up to 4,000 frames per second. The image resolution and quality will allow mechanical deformation and strain to be quantified. This kinematic information will then be used for the analysis of the stresses within the body subjected to external impacting forces. Data from carrots of materials under cyclical loading will be used for the indirect determination of frequency- and amplitude-dependent material constants. The deformation of biologically inspired structures subjected to transient loads will be used to assess their mechanical resistance and strength. Images of the human larynx will be obtained through the use of an endoscopic probe in order to quantify mechanical stresses in human vocal folds during various phonatory types and levels. This will help the assessment of impact stresses and their correlation with tissue damage.
