Low Frequency Sonar

Kevin Chan Examples 0 Comments

Housing resonances can significantly affect device performance, in particular at frequencies below 20 kHz where wideband hydrophones and parametric arrays can operate. Resonances can be difficult to predict and may only be detected late in the design cycle. With PZFlex’s highly efficient electro-mechanical solver, ability to generate multi-million element models and wideband results from a single run, it allows complex …

Tonpilz Transducer Simulations

Gerry Harvey Examples 0 Comments

Tonpilz devices are able to achieve a combination of low frequency and high sensitivity in a compact footprint which makes them ideal as projectors for sonar applications. PZFlex can accept models from CAD as well as generating models from simple wizards which makes modeling a single or a multi stack array very straight-forward. With our ability to run multi-million element …

Design of a Class IV Flextensional Transducer

Andy Tweedie Examples 0 Comments

Summary of the PZFlex Flextensional Transmitter Simulation The simulation analyzes the design of a Class IV Flextensional transmitter using titanium caps to maximize surface displacement. The most popular deployments of flextensional transducers include low ultrasonic frequencies applications from sonar to surgical actuation. Flextensional devices are compact and achieve high vibration amplitudes for a relatively low piezoceramic volume making them ideal …

2D Piezocomposite Array Measuring Crosstalk and Evaluating Surface Dilation Quality

Andy Tweedie Examples 0 Comments

Summary of the PZFlex Simulation This example created with PZFlex shows the modal displacement of a 7×7 element 1-3 piezocomposite phased array. This analysis is ideal for measuring crosstalk, and evaluating surface dilation quality. Below are several of the possible applications of this example: Medical imaging HIFU Sonar NDE Fingerprint sensing Technical details of the PZFlex simulation We centered the device …
