Mass spring damper system Tutorial Test 1
Derive the differential equation and find the transfer function for the following mass spring damper system. Tutorial Test 1 Q1 applied force (N) y mass displacement (m) f viscous friction (N.m.rad-1.s-1) k spring constant (N.m-1) where m is a mass (kg), a acceleration (m.s-2) F force (N). y Force,F a k f
Newton’s law Assuming viscosity friction force is proportionate with the changes in displacement dy/dt and spring force is proportionate with the displacement y. Therefore, Taking Laplae transform and assume zero initial condition
If the following parameters are given, calculate the step response m = 1, f=3, k= 2
b. Use block diagram reduction method to find the closed loop transfer function. Tutorial Test 1 Q2,,,,,
