Piezocomposite Phased Arrays

Piezocomposites are continuing to open new possibilities for sonar designers by offering across the board improvements on sonar performance. In order to unlock the true potential of piezocomposite technology designers require a simulation tool that allows them to explore a wide range of design options. PZFlex can deliver these results accurately allowing a new level of sonar performance to be realised.

Piezocomposites

Extract important metrics quickly and effectively from simulations. Electrical Impedance, Admittance, Conductance, Beam Profiles, Efficiency and other common outputs are available from standard toolsets.

Directivity

Far field beam patterns can be rapidly calculated using a Kirchoff extrapolation algorithm, allowing you to view results in either the time or frequency domain. This makes it easy to calculate the directivity of your device and ensures that the size of the finite element calculation can be minimised.

Single Crystal

Single crystal piezoelectrics offer significant performance advantages over polycrystalline ceramics, and piezocomposite configurations often best placed to take advantage of them. PZFlex can consider materials from any of the 32 crystal classes allowing easy material definition and alignment.

Hydrostatic Analysis

With full time domain and static mechanical solvers PZFlex can do more than just ultrasonics. Hyrdostatic analysis can be used to predict how transducers will behave at depth, allowing both stress and deformation analysis to be carried out in a single model.

Crosstalk

When fighting for wide acceptance angles sources of crosstalk must be understood and ultimately minimised. PZFlex efficiently considers large array structures, allowing crosstalk on adjacent elements to be analysed in detail, considering everything from voltage crosstalk to Lamb modes propagating along the length of the array.

Thermal

Device heating plays a major role in sonar transmitter design, often defining the top limit on Sound Pressure Level (SPL) that can be achieved. PZFlex has a fully coupled electromechanical solver that not only allows the internal temperature of a device to be predicted, but can also predict both internal stress and deformation.

PZT Devices & Stacks

PZFlex has been used by the sonar industry for over 20 years to assess and improve device design. From stacked tonpilz devices to flextensional configurations PZFlex can rapidly provide a clear picture a devices key performance metrics. With the power to consider entire arrays of devices PZFlex is ready to help designers deliver a new generation of high performance sonar systems.

Image
Tonpilz

Tonpilz devices offer a compact solution to creating high power low frequency sources. PZFlex allows all aspects of acoustic performance to be analysed, allowing you to create efficient, unimodal design which deliver the performance required by customers.

Acoustic Field

Fast extrapolation algorithms allow calculation of acoustic pressures in both the near and far field. This gives the designer the ultimate flexibility in assessing device performance, allowing everything from beamwidth to rear breakthrough to be accurately assessed.

Image
Hydrophones

Calibrated hydrophones are used in a wide range of applications and form the basis of many sonar test labs. PZFlex allows wideband analysis of hydrophone performance, providing confidence in device design across the whole operating bandwidth.

Mode Shapes

Understanding the modes of vibration supported by a device is often key to improving its performance. Mode shape analysis brings your data to life, allowing the designer to avoid parasitic modes of vibration that may hamper performance.

TVR & OCV

Accurate prediction of sensitivity is important for any sonar design, and PZFlex offers specific tools for directly calculating both TVR and OCV as a function of frequency. Sensitivity across the entire band of operation can be calculated from a single model, significantly reducing the time required to evaluate new designs.

Efficiency

Device efficiency is a key performance figure in most systems, and PZFlex allows this to be analysed in detail. Not only can experimental efficiency measurements be replicated, but power delivered to different parts of the device can be analysed giving the designer the full picture of how the system will perform.
