Example: Compute free vibration solution of a two The procedure to solve any vibration problem isDerive the equation of motion, using Newton’s laws (or sometimes you can use energy methods, as discussed in Section) Free Undamped Vibration. Reading materials: SectionIntroduction. Free vibration solution of multi-degree of freedom systems follows procedure similar to the one used for a single degree of freedom system Define Free Vibrations. It is at rest, and will stay at rest unless some other force acts on it LectureUndamped Free Vibration. The actual solution are formed by combining the basis together; transform the solution back to the original system Derive the equation of motion, using Newton’s laws (or sometimes you can use energy methods, as discussed in Section)Do some algebra to arrange the equation of motion into a standard formLook up the solution to this standard form in a table of solutions to vibration problems The system is transformed into. a set of independent ODEs of which its solution is readily determined. The system is currently in equilibrium, and the spring is not stretched or compressed. Derive the equation of motion of a single-degree-of-freedom system using different approaches as Newton’s second law of motion and the principle of conservation of energy. Linearize a nonlinear equation of motion. The governing equation is mu¨+ku =(14) where m is the mass matrix, ¨u is the acceleration vector, k is the stiffness FigureThis is a system consisting of a mass attached to the wall via a spring, sitting on a frictionless surface. The unknown coefficients can be determined via initial conditions. Solve a spring-mass-damper system for different types of free-vibration response depending on the amount Modal Analysis. Undamped means that there are no energy losses with movement (whether the losses are intentional, from adding dampers, or unintentional, through drag or friction) General solutions of the free vibration: in matrix form. The basic type of response of multi-degree-of-freedom systems is free undamped vibration. or. The system above is in equilibrium. The terminology of “Free Vibration” is used for the study of natural vibration modes in the absence external loading. The simplest vibrations to analyze are undamped, free vibrations with one degree of freedom. Modal analysis is the procedure for solving the simulta-neous system of ODEs. Analogous to single degree of freedom systems Consider an undamped MDOF system in free vibration.
