11:48 1 a uic.blackboard.com Project 3 (50 pts) Due Monday April 0, 2018 Chapter 4 socuses forced vibration of a mechanical sysm ad Chr 6 is on two degree of freedom problems. The first design problem ?"o select any sedan or tack and model the suspension system as a rigid body with 2 doprees of froodom This is a classical 2 degree of freedom problem and you are to research the gceral information such as dimensions suspension locations, weight of a car of your choice and model the firee esponse of this system. For the second problem, you are to research the Tapai 101 biding in Taiwan, which can be treated as a 2 degree of freedom tuned mass proiam You ane to solve for the mass spring constant, and the foece amplitude matrices of the fonced response of the building to an carthquake or wind sway, you decide which one you wan so model. Twe design examples have been selected for you to solve 1) Vehicle Sespension Solve for a vehicle's EOM if the car by treating it as a rigid body with a front and rear suspension system. Note that this is a two-degree of froodom poblem Model the free response ofthe system ustg two depees of freedom Y -clearly state the vehicle and specifications for that vehicle you are using and your souce of sefenences a) State ginven found assumed inSoemation. You must citle nefcnences of where you eètain information. (15 pts) b) Draw your mechanical sysiem. (5 pb) b) Draw the FBD with the minimum dimensions and variables defined ut are neoded to model the system. (10 pes) c) Deaw the ID with the minimum dimensions and variables defined that are necded so model the system. (10 pts) d) Solve for the 2nd ODE that describes the mechanicall sysm(0ps 2) Tapai 101 Model the Tapai 101 building under an carthquake or wind actuation This is an example of a continuous system that can be comverted to a 2 deg of fireedom tmed mass system a) State given found/assumed in formation. You must cite nefienences of where you ebtain information. (15 pts) b) Draw your mechanical system. (5 pts) b) Draw the FBD with the minimum dimensions and variables defined that are needed to model the system. (10 ps) c) Deaw the ID with the minimum dimensions and variables definod that are necded so model the system. (10 pts) d) Solve for the 2nd ODE that describes the mechanical syem (30ps

Explanation / Answer

Illustrated below is a circular disk cam assembly with a helical compression spring. The spring has plain ground ends. The cam is a circle with an eccentricity, e=0.75 in. The total follower displacement is 2e or 1.5 in. A rod with a 1.5 in
