激光位移传感器在测量物体表面变形的应用

冲击可能造成物体的瞬间变形或损坏,也有可能影响设备的精确度,甚至会造成功能失灵。鉴于应变片接触到物体表面会引起很大的冲击变形,利用激光位移传感器测试对象表面的瞬间变形量,提高了物体表面抗冲击特性模拟方法精度,理论分析物体的冲击信号。

Application of Laser Displacement Sensor in Measuring Object Surface Deformation

Impact on object may cause instant deformation or damage, also may affect device accuracy, and even cause functional failure. Because the strain gauge contacting surfaces will cause a great impact deformation, a laser displacement sensor was used to test the instantaneous deformation of the subject surface, to improve the precision of the simulation method of the impact resistance of the object surface. The impact signal to the object was analyzed theoretically.
