| 摘 要： | 以一端固定、另一端为任意边界条件的振动梁为例,文中提出通过分部积分方法设计特定形状的PVDF薄膜测量其结构位移.这种分部积分方法得到的PVDF位移传感器形状不但与外激励力的性质(如激励力类型、位置以及频率等)无关,而且不需要振动梁的模态信息.实验结果表明:这种位移传感器的设计是可行的.

| Abstract: | With the example of vibrating beams with one clamped end and another arbitrary boundary condition end,this paper presented a new methodology to design the displacement sensor using a shaped PVDF(polyvinylidene fluoride) film based on the basis of the integral in parts approach.The PVDF sensor shape was shown independent of property of the excitation(the type,position and frequency,etc.).Furthermore,the design method does not require knowledge of the structural mode shapes of the structures.The experimental ... |
