激光多普勒测振仪能帮助客户开发出更高效的超声波加工工具。Polytec 的 LDV 对于 FE 模型验证不可或缺，其价值已在许多工业应用中得到证实，如引线键合、超声波焊接或超声波食物切割等。使用扫描式激光多普勒测振仪，可以直接获得超声波发生器的振型，通过与仿真模型进行对比，可靠地实现最佳效能水平。即使在焊接过程中，LDV 也能够测量工件在接触时的振幅。无论是在开发阶段，还是在生产过程中出现偏差时，LDV均能提供重要信息。
In addition to plastics technology, ultrasonics also enables metal ultrasonic welding or the joining of different materials, such as metal and fiber-reinforced plastics (CFRP). Wire bonding – which is fairly widespread in microelectronics contacting – is yet another application. Also, the determination of the relative velocity and displacement amplitudes by performing a differential measurement, which is necessary for forming a highly stress-resistant joint is a popular application. Last but not least, laser vibration testing allows reliable calculation of the vibration amplitudes under operating conditions – excellent for assessing the ultrasonic welding process.
