چکیده
Measurement system analysis (MSA) technique is an important method which is used to analyze statistical discreteness and measurement capability of a measurement system, and also one of quality improvement techniques. The paper describes analysis principle and methods of repeatability and reproducibility (R&R) in MSA, introduces MSA techniques into the field of non-destructive testing (NDT). Based on an example of ultrasonic testing, the value of R&R is calculated and discussed. The results show that MSA technique can evaluate effectively measurement capability of ultrasonic testing system, and also can be applied in other NDT system.

متن کاملA simple and novel method for acoustic streaming power measurement of ultrasonic horn
Ultrasonic horn with transfer of acoustic wave into an aqueous solution results in unique properties. When, transfer of sound wave into a liquid results in liquid movement in the direction of wave propagation which gradually loses its energy due to the viscous friction. This wave motion induces a flow which is known as acoustic streaming or micro-streaming. In this article, a simple innovative ...
