Unformatted text preview: block ( y ). k 2 m y x k 1 b 2 b 1 (a) What is the system’s transfer function? (b) Assuming that m = 100 kg, b 1 = 0.5 Ns/m, b 2 = 1.5 Ns/m, k 1 = 5000 N/m and k 2 = 3995000 N/m, what will the peak to peak amplitude of the block’s vibrations be if x ( t ) = 0.002cos(200 t )? What will the peak to be peak amplitude be if x ( t ) = 0.002cos(3000 t )? (c) Assuming the same values, use the asymptote approach to create a reasonably accurate Bode plot (magnitude and phase) for the system. Once you have finished your masterpiece, check that it reasonable by producing another plot using Matlab. Submit both your plot and the Matlab plot. 4/. The transfer function of a system is ) 200 )( 20 ( 10 + + s s s Using the asymptote approach, sketch a Bode plot (magnitude and phase) for the system....
