中文摘要: |
设计换能器时一般忽略螺杆的影响,将前、后盖板和压电陶瓷晶堆作为均匀的实心杆件,这种方法有一定的近似性。将任意空心变截面杆等效为同种形状的实心杆件,并推导出了出几种常见形状空心杆件的等效几何参数及其网络传输系数,从而可以利用等效网络的方法方便准确地设计超声振动系统。 |
英文摘要: |
The methods of ignoring screw and thinking of front cover,rear cover and piezoelectric as solid bars are somewhat approximate but rather easy for transducer designing.The physical parameters and network transmission coefficients of the equivalent solid horns of any hollow horns with variable cross-section are derived,and so the original design methods could still be used,which facilitate the design of the ultrasonic vibration system. |
