I. Main Experiments:
The teaching laboratory is established as one of the teaching and practice bases for courses of the department in electromechanical testing and inspection, and automatic control. It serves as a solid platform for experiment conducting and practical learning to develop students’ skills in bridging theory and practice, applying their acquired knowledge, and engaging in extracurricular scientific research and innovation activities.
The laboratory is designed mainly for undergraduate and graduate students of mechanics-related majors to learn and conduct experiments related to electromechanical control courses. Through experiments in single-chip microcomputers, programmable controllers, and hardware and software design for DSP control systems, students will develop a good mastery of currently advanced control methods in the automatic control field. The series of experiments in fluid media-based process control systems and inverted pendulum control systems will enable them to deepen their understanding of basic control engineering theories. With the guidance of laboratory instructors, they will independently select their own electromechanical control-related topics and complete the entire process, from experiment plan design and hardware development to software programming and final debugging. Additionally, students will gain deeper insights into power electronics technology with experiments involving characteristic testing of power electronic devices and circuit debugging. A variety of hands-on practices will help to increase students’ interest in learning and deepen their grasp of theoretical knowledge, ultimately nurturing their analytical and problem-solving skills.
This laboratory also provides these students with teaching experiments related to testing and inspection courses. Students can acquire a strong grasp of the fundamental principles and performance evaluation methods related to the two key components of testing and inspection systems through sensor testing and signal analysis and processing testing. The exploration of acoustic wave parameter measurement and electromagnetic field spatial characteristics can enhance students’ comprehension of the physics underlying non-destructive testing methods. Additionally, conducting the testing of ultrasonic inspection, eddy current, and acoustic emission can further allow them to master the essential procedures associated with commonly used non-destructive testing methods. This proficiency enables students to confidently perform basic non-destructive testing procedures based on their acquired knowledge.
Some of the experiments provided by the laboratory include the (1) ultrasonic longitudinal wave detection experiment, (2) eddy current testing experiment, (3) acoustic emission experiment, (4) sensor experiment, and (5) signal analysis and processing circuit application experiment.
