- Two Translation Mechanical Systems Are Sketched In The Figure Below Both Are Formed Of A Body Of Mass M Two Springs Of 1 (330.68 KiB) Viewed 47 times
Two translation mechanical systems are sketched in the figure below; both are formed of a body of mass m, two springs of stiffness k and a damper of coefficient c. An input force f= Fisin(ot) is applied to the body in both systems along the direction x. Which of the two systems performs better in the frequency domain in terms of reducing the steady-state displacement amplitude X of the body ? Known are: m= 1kg, c= 5 Ns/m and k = 100 N/m. Are there any values of the frequency o for which the two systems perform the same? If yes, calculate those frequencies. Hint: Use the transfer function whose output is X(s) and input is F(s) to compare the frequency response plots of the two systems. f 13k 44 f 4死 Тх m fx k} He MT la) 16/
