Abstract

Abstract

A finite element analysis method with coupled mechanical and electric analysis is adopted to evaluate the performance of a three component piezoelectric balance. Static force, modal and transient response analyses are done in this research. The relationship between the balance output and the applied load is obtained by static force analysis to evaluate the main coefficient and interaction coefficient of the balance. The vibration frequency and vibration mode are obtained by modal analysis to evaluate the balance frequency response characteristics. The transient response analysis is done to evaluate the characteristics of the balance with impulse force, and to evaluate the compensation characteristics of accelerometers. The ANSYS analysis results show that, the piezoelectric balance has a large main coefficient, a small interaction coefficient, and high response frequency; the accelerometers can be used to compensate the balance signal, which can meet the requirements of the shock tunnel aerodynamic force test. The result of the balance calibration and shock tunnel test shows the same balance characteristic with that of the simulation results. Through this research, the characteristic of the piezoelectric balance is evaluated for the balance design, which is useful in the balance structure optimal design and determining the position of the sensitive element.
