Download LabView Workshop: Introduction to LabView Software for Engineering Students and more Lab Reports Mechanical Engineering in PDF only on Docsity! LabView Workshop Many engineering measurement, control, and manufacturing systems are controlled with a computer. In addition, many consumer products are controlled with a microprocessor, or a programmable logic controller. A key component to these is the software that is used. The software converts information that is meaningful to people into information that is meaningful to equipment that is being operated (and visa versa). This workshop is designed to provide introductory experience with LabView software. LabView software is an industrial strength software tool that is used for many real applications. In this workshop you will perform calculations and display results, but you will not interface with sensors and actuators. In subsequent labs you will use LabView to interface with sensors and actuators, as well as to perform calculation and display results. Objectives Learn basic LabView programming techniques. Review beam deflection theory. In Lab Exercises 1. View the LabView video introduction. Your T.A. will hand out a worksheet for you to fill-in as you view the video. 2. Open and run the example temperature vi (from the desktop). Comment in your notebook on potential applications of this program. Do not spend more than five minutes on this. The intent is for you to be aware that there are examples available to see how to solve different types of problems. 3. Develop a LabView Program that will calculate the deflection of a cantilever beam (see figure 1 below). Read in the parameters in the cantilever beam strain formula from the front panel. Program the calculations in the diagram with symbols and wiring. Display the results on the front panel. Ebh PL 3 34 =δ 4. Enter in values for each parameter and run the program with the light bulb turned on. Run the program with the single step feature. Comment on the data flow. Is it what you would have expected? 5. Check the computer results with your calculator. 6. Save an HTML - GIF file of the front panel and the diagram and print these for your notebook. Your T.A. can assist you with this. 7. Measure the dimensions of the beam in the lab (see figure 1 below). Note the material that the beam is made off. Put a load on the beam and measure the deflection. Enter the parameters from this experiment into your LabView program and calculate deflection. Contrast the measured and calculated values. 8. If time permits, re-write the calculation part of your diagram using the formula node structure. Your T.A. can assist you with this programming approach. Discussion Questions 1. How is the order of execution of LabView programs determined? 2. What color of wire represents an integer?
