A computer processing method is expounded which examines grinding mill load with piezoelectric strain transducer based on the investigation and the preliminary experiment--the data collection system of the grinding mill load.
The piezoelectric strain constant d33 was about 30 pC/N. Microwave irradiation technique improves the interfacial interaction between the piezoelectric ceramic powders and the matrix owing to physical effects,which is of benefit to pole the piezoelectric ceramic.
M?ssbauer spectroscopy, the piezoelectric strain tensor element d14 the elastic constant s55, and the dielectric function ?11 of the samples were examined.
In this study the function of the iron in the collagen structure was examined with the aim of increasing the value of the piezoelectric strain tensor element d14.
The study concludes that controlled modification of the MPB composition of PZT using 0.1 mol % CeO2 results in substantial enhancement of piezoelectric strain coefficients, dielectric constant and electromechanical coupling coefficients.
Third, the low resistivity of the composite prevents the poling process and reduces the piezoelectric strain constant.
It is found that piezoelectric strain constant decreases exponentially as the amount of doped piezomagnetic materials in the composite increases.
In order to discribe piezoelectric strain optical modulator (PESOM), we analyzed LiNbO3 crystal resonator excited by distributed piezoelectric source in detial in this paper. The quantitative results of structure of strain field are obtained in one-dimension approximation for PESOM.
