Project Outline Ultrasonic non-destructive testing has been commonly used for flaw detection in structures. In the structure industry, the quality control of the fabrication products, as well as the equipment used to fabricate them, is performed by means of NDT (Non-Destructive Testing) methods. This control procedure is still more relevance when aspect of public security is present such as in aeronautics and nuclear industries. In many Non-Destructive Testing applications, piezoelectric transducer system employs high frequency ultrasonic waves. The ultrasonic radiation of these piezoelectric transducers is used as a tool to visualize internal parts of a structure. The propagation of these pulsed elastic waves is then relied on to provide necessary information about the internal structure of a tested medium by means of the analysis of scattering, reflections and attenuation in the mechanical discontinuities encountered along the ultrasonic path. Therefore, the requirements of design the piezoelectric system consist two important parts: accuracy and efficiency. In fact different Non Destructing Testing (NDT) systems have been designed. However, to improve the accuracy and efficiency, further researches are required. This project has been of interest to me because it can be applied to numerous structural applications. To finish this project, a lot of researches, designing, as well as testing on piezoelectric transducer are required. The project will focus more on comparison of study of piezoelectric transducers, as well as designing a suitable controller by the MATLAB software. During the designing, accuracy and efficiency will be the most important factors. 3. Capabilities of the student In order for me to complete this project, many researches is needed to be done throughout the project undertaking. In addition, the skill of design and modeling system is also required. Towards the project completion, I will use MATLAB software to develop and test the system. This project may bring many challenges, however, during my study in Bachelor of electrical engineering, it has helped me to improve myself and I am very familiar with many skills that will be needed for the success of this project. Some of the areas during my undertaking on Bachelor of electric engineering that will come in hand to complete this project include: Engineering Communication: This unit has helped me to develop communication skills in an engineering workplace setting. Some of the areas study include basic theories and principles of human communication; researching within the various discipline areas that inform the study of communication. This unit gives me the basic skill of doing researches in engineering area. Circuit Analysis: This unit entails the basic theory of various circuits. MATLAB will be used during the study of this area. Introductory Control: This unit involved the designing and modeling skills of a control system, in both analog control and digital control. 4. Objectives and Scope 4.1 Objectives Our goal is to design and build a fully functional piezoelectric system to achieve the aim of testing structural medium. The system function will be used to test structural medium non destructively. 4.2 Project Value Piezoelectric transducer systems are used routinely in a diverse range of applications, including non-destructive testing, SONAR and industrial process monitoring. Successful design of a sensor device for a specific application is often very difficult, owing to its complex interaction both within the device and its operational medium. Therefore, it is important to improve the accuracy, efficiency and safety of piezoelectric system by continue designing the system since piezoelectric are so closely related to our real world. 4.3 Project Viability The project will depend on the previous tasks that were undertaken. If the system does not satisfied the basic tests and do not met the threshold then a remodeling may be required. 5. Method 5.1 Preparation: Every week I will meet the project supervisor Dr. [Insert Name] to inform him on the progress of the project, get the his feedback of the work and the advices of what need to be included in the project. Too much research will be needed at this point. 4.1 Literature Review: Gaining knowledge on the past literature on piezoelectric transducer systems. Further literature review of basic circuits, components, system operations and so forth. Gain understanding the MATLAB software, especially the SIMLINK part by self-study. 5.2 Modeling and Designing Set up the performance of the system then base on this to modeling the system. Design the controller of this system. 5.3 Performance Testing Piezoelectric system will be tested, whether the system has reached the threshold set up at the beginning of the project. The final results will also be compared with the theoretical results. 6. Strategies and Resources 6.1 Software Requirement MATLAB software: this software will be used in modeling the piezoelectric system, simulate the system and test the results. Ms/Word: this software will be used to write and compile this reports, while Ms/Excel will be used to analyze data. 6.2 Equipment required Piezoelectric transducer model: The piezoelectric transducer model will be helpful to understand the whole system. 7.
