DEMONSTRATION PROBLEMSi) For free vibrationAfter the first vibration, the system meets its own disturbance, that vibration is called as free vibration. The free vibrations are represented by homogeneous Ordinary Differential Equations. The Types of free vibration of single degree of freedom systems1.harmonic motion,Free vibration of undamped SDOF systems,Free vibration of damped SDOF systems ii) For forced vibration If any external force is applied to the system, the reaction of the system is called as forced vibration. The frequency of the system is matched with external force frequency, it leads to heavy oscillation because of the occurred resonance. The forced vibrations are represented by Non homogeneous Ordinary Differential Equations.Types of forced vibration of single degree of freedom systems1.Harmonic excitation Base excitation

iii)This figure shows the response of car due to the road roughness and road defects. Due to the road roughness, the car dynamics, drainage, ride quality and dynamic loads is affected.The nonlinear motion of the object is getting time delayed and the harmonics are dampering from the domain so the vibration control is under progress to develop the stablilization in the system. The developing protocol in the dampering circuit creates additional damping in the oscillations developed IV) Include in your Simulink model suitable non-linearity’s, discuss and show how or if these will affect the previous analysis. You may have to generate some extreme road defects to show the operation of the non-linear properties.

This is the single degree of freedom simulation model. The Simulink is used to provide the simulation model.it provides more response factor. The input of model is mass. It is used to perform the summation operations. By using the Integrator, the expression is decoded and the output is controlled.Result:This is the implemented single degree of freedom response. This done by Matlab. The input for response is mass value and sine wave. The output shows the amplitude and bias range.

The development of the system enhances the domain in the single degree of freedom response and this MATLAB is enhanced with the development of the idea in the tenangrad of the sinusoidal output where the region of the stabilization takes placev) Damping helps to isolating vibration and reduces transmitted vibration. Based on your analysis write a paragraph on the effect of damping in affecting your car’s performance i.e.Where would be better to use high damping; Where would it be better to use low damping; and how does the damping levels you have chosen in your car affect passenger comfort and the wheel road contact force.Dampingis major features of noise proofing an existing or fresh wall structure.Dampingis used to decreasing or avoiding kept energy shaped by sound. If a structure haslowdamping, soundvibrationcan travel across it for great distances. The tires have theautomobile characteristics of handling and ride. It has the reaction point of vehicle at theroadway. It has ability to manage the problem at the road. Because it is the final link from thedriver. The springs, linkages and dampers are used to manage the tires basic functions. Thedamping is used to control the spring effect in the vehicle (vibration).Damping is used tocompare engineering material for the applications. High damping is used in vibration control,reducing increased heat, and shock absorption and noise control.Low damping is used forincreasing sensitivity in sensors and definite accuracy instrumentation.In the increasing sensitivity of the the module due to heat and other mass related transferfunctions the newton’d Raphson model is included and the research have been developedto control the shock absorption and other damping oscillations of the accuracytransmissions.
