3D-Scanning-Laser-Doppler-Vibrometer

自然界和技术中的物体会振动，每一次振动都取决于能量输入、物质组成和物体结构。一般来说，机器的振动会导致材料应力、磨损、噪音产生和更高的能耗，因此必须进行优化。与触觉运动传感器一样，无需向振动系统输入质量的非接触式光学振动测量提供了相关优势。为此，克劳斯塔尔工业大学的各个工作小组正在用激光多普勒振动仪（LDV）进行振动分析。申请人在其工业活动期间已经共同开发了3D扫描激光多普勒测振仪（3D- rldv），允许对振动行为进行非接触分析，并且在本申请中申请这种设备用于他自己的激光多普勒测振新技术研究。然而，3D扫描激光多普勒振动计将向克劳斯塔尔理工大学材料工程中心的所有研究人员开放，用于振动分析。然而，具体来说，申请人的研究小组设想该系统用于户外跟踪应用，并将首次用于测量户外移动物体（例如，移动的汽车和由这些车辆或风力涡轮机叶片产生的振动）上的3D振动。为此，将采购一个具有开放接口的设备，并使用专有软件解决方案进行扩展，以便大型设备将主要用于激光多普勒振动测量新技术的研究。

Objects in nature and technology vibrate and each vibration depends on the energy input, the material composition and the object structure. In general, vibrations in machines can lead to material stress, wear, noise generation and higher energy consumption and must therefore be optimized. A contactless optical measurement of vibrations without mass input into the vibrating system as with tactile motion sensors offers relevant advantages. For this reason, various working groups at the TU Clausthal are engaged in vibration analysis with a laser Doppler vibrometer (LDV). The applicant has already co-developed 3D scanning laser Doppler vibrometers (3D-RLDV) during his industrial activity, which allow non-contact analysis of vibration behavior, and is applying for such a device in this application for his own research of new technologies in laser Doppler vibrometry. However, a 3D scanning laser Doppler vibrometer will be accessible to all researchers at Clausthal University of Technology for vibration analysis at the Clausthal Center for Materials Engineering. Specifically, however, the system is envisioned in the applicant's research group for outdoor tracking applications and will be used to measure, for the first time, 3D vibrations on moving objects (e.g., moving cars and vibrations generated by these vehicles or wind turbine blades) outdoors. To this end, a device with open interfaces is to be procured and expanded with proprietary software solutions, so that the large-scale device will be used primarily for research into new technology for laser Doppler vibrometry.
