Three Degree Of Freedom

An approximate method of arriving at a solution to nonlinear vibration problems is discussed. With the technique presented which involves system discretization, solutions for free as well as forced vibrations can be derived by an application of the stationary functional method using discrete normal modes. Two examples are analyzed as follows to illustrate the applicability of the approach as a useful tool in obtaining solutions to nonlinear vibration problems. (1) A three-degree-of-freedom spring-mass system with nonlinear restoring springs, and (2) a nonuniform, rotating blade mathematically modeled as a discrete cantilevered beam vibrating in the plane of rotation. The analysis reveals a definite advantage afforded with discretization in that nonlinear modes higher than the fundamental can also be easily generated—a significant improvement over the use of shape functions in conventional nonlinear continuous system analysis.

The designs of automotive suspension system are aiming to avoid vibration generated by road condition interference to the driver. This final project is about a quarter car modeling with simulation modeling and analysis of Two-Mass modeling. Both existing and new modeling are being compared with additional spring in the sprung mass system. MATLAB program is developed to analyze using a state space model. The program developed here can be used for analyzing models of cars and vehicles with 2DOF. The quarter car modelling is basically a mass spring damping system with the car serving as the mass, the suspension coil as the spring, and the shock absorber as the damper. The existing modeling is well-known model for simulating vehicle suspension performance. The spring performs the role of supporting the static weight of the vehicle while the damper helps in dissipating the vibrational energy and limiting the input from the road that is transmitted to the vehicle. The performance of modified modelling by adding extra spring in the sprung mass system provides more comfort to the driver. Later on this project there will be comparison graphic which the output is resulting on the higher level of damping system efficiency that leads to the riding quality.
