ME 481 – Spring 2011 - HW03 Name ________________________ 1) Review all the Working Model examples in folders “DemoFiles”, “Simulations” and “Tutorials” and list your three favorites. ____________________ ____________________ ____________________ 2a) Develop a Working Model (WM) simulation for an in-line slider crank in a single cylinder air compressor with 2.75 inch bore, 1.97 inch stroke and connecting rod length 4.33 inch operating at constant 1000 rpm crank speed. Export the position, velocity and acceleration of the piston into a *.dta file. Be certain to start your simulation at Top Dead Center (TDC). Attach a screen shot of your WM mechanism. 2b) Use MS-Notepad or MS-Word to remove the header lines from the *.dta file. Write a MATLAB program to read the data from the modified *.dta file with the

Unformatted text preview: load function. 2c) Program geometric equations in MATLAB to compute piston position, velocity and acceleration for the slider crank. Attach hard copy of your code. 2d) Create three graphs with WM and geometric equation results on the same graph. Use circle symbols for your WM results and a continuous line for your equation results. a) piston position versus crank angle b) piston velocity versus crank angle c) piston acceleration versus crank angle 2e) How many standard CFM (cubic feet per minute) of air will this compressor deliver? CFM ________________________ EXTRA CREDIT Create three additional graphs similar to part 2d) above that show the difference between exact geometric equations and binomial series approximations for this slider crank as a function of crank angle....
