Electronics are often housed in an enclosure as part of a system (computer, control system, etc.) This enclosure offers protection and may be mounted directly to a mechanical system such as a car, ship, aircraft, etc. These electronics may be subjected to harsh vibration environments. Consider a control unit in your car. When you drive over rough roads, the electronics are subjected to such a vibration environment. Understanding how the electronic PCB boards will vibrate, deform, and be stressed is of concern to those designing and certifying the electronics. In this problem, we will subject an electronics enclosure with an enclose PCB assembly to a harmonic based excitation, simulating periodic, cyclic excitation that may result in dynamic amplification of the PCB, and the associational unwanted deformations, stresses and strains. One key parameter to quantifying the magnitude of the deformations, stresses and strains is the damping that is specified for the system. In these simulation exercises, you will be setting up the simulation and extracting key results quantities.
