PLAGIARISM
Plagiarism is the presentation of the expressed thought or work of another person as though it is one's own
without properly acknowledging that person. You must not allow other students to copy your work and must take
care to safeguard against this happening.
Plagiarism is a serious offence. As set out in University Regulation 6.1.1., students who are caught plagiarising
will, for a first offence, be given a zero mark for that task. A second offence will result in a failing grade for the
Course(s) involved and any subsequent offence will be referred to the Student Discipline Committee.
Declaration
Except where appropriately acknowledged, this assignment is my own work, has been expressed in my own
words and has not previously been submitted for assessment. I have also retained a copy of this assessment
piece for my own records.

1. Abstract
This report aims at determining the vibration machine and dynamics of a vehicle in motion over
a road with unevenness. One of the greatest effects is the resonance vibration with amplifies the
vibration response more than the level of deflection, strain and stress caused when static loading is
placed. The data collected in this research focuses on the internal combustion engine and the design of
the vehicle. In studying the vibration of the vehicle, the vehicle suspension and car body are defined
and data collected is recorded in orthogonal axes; in the X, Y, and Z. The vehicle has a damping
element that gives a high damping at low frequencies so as to obtain the duty cycle and vibration
constants.
2. Introduction
In a vehicle design it is quite paramount to determine the vibration factor based on a number of
specifications. The dynamics of a vehicle need to be discussed clearly so as to avoid vibrations which
are undesired in roadside structures as well as for other elements in the vehicles [1]-[3]. The designer
focuses on the vibrations developed or transferred from the road to the car body structures based on the
road surface. Another aspect, thoroughly, discussed is the vibro-acoustic which considers the
possibilities of vibration and acoustic signals in diagnosing and researching. One of the greatest effects
is the resonance vibration with amplifies the vibration response more than the level of deflection, strain
and stress caused when static loading is placed. The vehicle system payload parameters determine the
material properties such as mass, stiffness, damping attributes, boundary conditions of the structure
[4].
The data collected in this research focuses on the internal combustion engine and the design of
the vehicle. The amount of vibration caused to the system is estimated to be within the 3-axis
rotational velocity [5]. The speed of rotation may range from 750 rpm to 3000 rpm. In studying the
vibration of the vehicle, the vehicle suspension and car body are defined and data collected is recorded
in orthogonal axes; in the X, Y, and Z. To determine the measurement point section and vibration
propagation from engine to human being, the following section is developed [6],
