Designing a measurement system for a specific application can be a daunting task. A 2nd order mechanical system (cantilever beam) is presented to the Mechanical Engineering Laboratory II student groups. They are to measure the dynamic response at three non-colocated measurement points. The students are required to select three different types of measurement devices (from several possible transducers), determine suitable locations, digital data acquisition requirements, etc. to determine the "best" method to address the problem. All measurements must be compared to each other. This requires spatial adjustment as well as integration/differentiation of displacement, velocity and acceleration measurements; these may be acquired from an LVDT, accelerometer, laser, eddy current probes, strain gage, etc). The use of a dynamic system model (using MATLAB and/or SIMULINK) to determine the actual response due to impulsive and step loading is required. The optimization of the parameters (signal type, location, transducer sensitivity, etc) is required to provide the "maximum" signal for the ADC specified for the data acquisition. A full formal report is prepared to document all aspects of the project effort along with a formal presentation. The details of the project along with some results obtained from various student groups is also presented.
Laboratory experiments are an excellent opportunity for students to provide real-world practical solutions to problems that may not have an “answer at the back of the book”. Students learn best with hands-on projects and problems with practical purpose . These types of problems tend to
