Single Degree Damped Vibration

Level 2 labs: Single Degree Damped Vibration

Summary
In this experiment, a single-degree of license trunk was set-up by using a slotted set, an cover dashpot, a spring of known ineptitude and a publish attached to the vibrating frame and a paper strip compulsive by a synchronous motor provide a means of producing time recordings, by plotted for three systems (Undamped, Damped and apologize-Fall) was utilise to perform the calculations. The natural frequency of vibration of the spring potty system was 30.65 rad/s in the experiment without damping and examine obtained to the formula that been given is 29.86 rad/s. The damping coefficient was found in flake of turns 2.75-4 and the range was 43.3 kg/s to 30.2 kg/s. In the ii free-fall processes were carried out using 1 kg and 2 kg slotted mass, the damping coefficient range is 1261.2 kg/s to 193.3 kg/s and 1512 kg/s to 246.9 kg/s.

Introduction

The easyst mechanical model of a vibration system is a damped single degree of freedom system.



A single degree of freedom system is a spring-mass-damper system in which the spring has no damping or mass, the mass has no stiffness or damping, the damper has no stiffness or mass. Furthermore, the mass is allowed to move in only bingle direction. In this lab report, it has used three different systems (Undamped, Damped and Free fall of piston through oil). The undamped system is no damping in the system and oscillate freely at their natural frequency. The damped system is a damping affect the amplitude of oscillations and it oscillates shortly. In this experiment is to read the natural frequency of vibration of a simple spring-mass system, the damping coefficient of an oil-dashpot-damped from the target of decay of the amplitude of a vibration of a simple spring mass damped system and the damping coefficient of an oil dashpot damper from the speed of...If you want to get a full essay, order it on our website: Orderessay
