this is about the reduction of the unwanted vibration in the drone.Vibration analysis is defined as a process for measuring the vibration levels and frequencies of machinery and then using that information to analyze how healthy the machines and their components are. While the inner-workings and formulas used to calculate various forms of vibration can get complicated, it all starts with using an accelerometer to measure vibration. Anytime a piece of machinery is running, it is making vibrations. An accelerometer attached to the machine generates a voltage signal that corresponds to the amount of vibration and the frequency of vibration the machine is producing, usually how many times per second or minute the vibration occurs.
All data collected from the accelerometer goes directly into a data collector (software), which records the signal as either amplitude vs. time (known as time waveform), amplitude vs. frequency (known as fast Fourier transform), or both. All of this data is analyzed by computer program algorithms, which in turn is analyzed by engineers or trained vibration analysts to determine the health of the machine and identify possible impending problems like looseness, unbalance, misalignment, lubrication issues and more.

4. Abstract
• The objective of this study is to understand the forces and vibrations affecting the
flight performance of drones.
• The forces acting on drones are categorized into thrust, drag, weight, and lift.
The study also examines the impact of these forces on the drone's stability and
maneuverability.
• Vibration can cause significant damage to the drone's mechanical parts, affecting
its reliability and longevity.
• Therefore, it is crucial to analyze the vibration levels and their sources to ensure
that the drone operates within safe limits.
6. Introduction
• A drone is an un manned aircraft . Drones are more formally known as un
manned aerial vehicles or unmanned systems.
• Essentially a drone is a flying robot that can be remotely controlled or fly
autonomously using software controlled flight plans in its embedded system .
• Quadcopter have become increasingly popular due to their versatility and ability
to fly in tight spaces .however their forces and vibrations can impact their
performance .
• This presentation will analyse the forces and vibrations of quadcopter in a
comprehensive study .

8. Objective of the project
Vibration analysis on the drone:
• Vibration is a mechanical phenomenon where by oscillations occur about an equilibrium point.
Why vibration?
Vibrations occur in all moving machinery while in operation. Every material has a characteristic pattern of vibration
under specific conditions. Measuring, recording, and studying the changes in these vibration characteristics can be
used to understand the changes in the test material itself.
What is vibration analysis?
• Vibration analysis is a process that uses vibration signals to identify anomalies in vibration patterns. A change in the vibration
pattern indicates a change in the physical properties of the test object.
• In equipment maintenance, vibration analysis helps us track and evaluate the condition of our equipment.
• When an anomalous pattern is observed, we can conduct root cause analysis to identify the reason for the change. Once we
know that, if it is deemed necessary, we can schedule appropriate corrective maintenance action.
9. Force analysis on drone:
• A force analysis on a drone involves examining the various forces
acting on the drone and how they affect its motion.
• Engineers often use computer simulations or wind tunnel tests to
determine the precise forces acting on a drone under various
conditions.
• Once the forces acting on the drone are determined, engineers can
optimize its design and control algorithms to achieve optimal
performance and stability.
• For example, a drone may be designed to generate more lift or
reduce drag to improve its flight time or range.
11. • PETG – (polyethylene terephthalate glycol-modified)
Why PETG ?
• High strength, lower shrinkage, and smoother finish than ABS and PLA
• Combines good strength with ductility, making it a good, tough material for
mechanical parts.
• Good chemical resistance
• In recent years this material become a very popular material for 3D printing as it
combines a number of great properties of both ABS and PLA
• Good hydrophobicity
• Good chemical resistance
Material used in fabrication of drone
12. EXPECTED OUTCOMES
• To find the natural frequency of the quadcopter.
• It will use to reduce unwanted vibration.
