IRJET- Design and Fabrication of Pneumatic Vibrator
0 likes•47 views
This document describes the design and fabrication of a pneumatic vibrator. It discusses how pneumatic vibrators are used in various industries to solve material flow problems by applying vibration. The working principle is explained - compressed air is passed through a nozzle and hits the blades of an unbalanced mass mounted on a rotating shaft, producing vibration. Mild steel is used for fabrication due to its low cost and material properties. A 3D model of the pneumatic vibrator is created using SolidWorks software. The document concludes that pneumatic vibrators can make tasks safer, easier and more efficient by saving time and money.

carbon steels contain less carbon than other steels and are
easier to cold-form, making them easier to handle.
A waveform is a graphical representation of how the
vibration level changeswith time. Theinformationcontained
in the waveform depends on the duration and resolution of
the waveform. The total time period over which the
information is obtained from the wave form is called the
duration. The level of detail is defined as resolution or the
number of samples present in the waveform.

Building a model in SolidWorks usually starts with a 2D
sketch (although 3D sketches are available forpowerusers).
The sketch consists of geometry such as points, lines, arcs,
conics (except the hyperbola), and splines. Dimensions are
added to the sketch to define the size and location of the
geometry. Relations are used to define attributes such as
tangency, parallelism, perpendicularity, and concentricity.
The parametric nature of SolidWorks means that the
dimensions and relations drive the geometry, not the other
way around. The dimensions in the sketch can be controlled
independently, or by relationships to other parameters
inside or outside of the sketch.
3. CONCLUSION
Not only does a pneumatic vibrator save time and money it
can also make tasks safer and easier. Simple production
process. Low manufacturing costs. Improve production
quality. It can maximize process efficiency. Electricity
consumption.

They require different piping, horozoutal, conveyor, weighing, arrangement, separate, coding, life testing equipment dust, collecting, and main in process automation. Material characteristic (moisture, s.g., size…) and equipment design (shape, stuff…) usually lead to accumulated or even decreasing material delivery flow problems in working flows. Pneumatic vibrator provides the best solution by applied it onto problem position. By using pneumatic vibrator to shake or peel off clog material from applied object or to low down friction between materials to make it move smoothly in automatic production.. Key Words: Pneumatic, Vibrator, Analysis, Properties, Design etc… 1. INTRODUCTION The pneumatic vibrator isa versatilepieceofequipment that is essential to many industries. In construction for example, the pneumatic vibrator is used to remove excess moisture and pockets of air from freshly poured concrete ensuring that the end result is uniform, attractive and above all, safe. In agricultural settings these easy to use vibrators are responsible for emptying silos, among other things, while in pharmaceuticals a pneumatic vibrator can separate fine powders or be used as a feeding mechanism. Not only does a pneumatic vibrator save time and money it can also make tasks safer and easier. A vibrator is a mechanical device to generate vibrations. The vibration is often generated by an electric motor with an unbalancedmass onits driveshaft. 1.1 WORKING PRINCIPLE: It is simple structured small size vibrator with strong vibrating force. The vibrator is responsive for sudden activation deactivation which eliminates the damage of the equipments to the minimum level. The vibrator is forced by compressed air easily operated without spark. The working principle does not cause sparks which can be applied in hazardous humid or other severe environment.Powerforce, frequency and amplitude can be adjusted while operating. The compressed air is used for pneumatic vibrator. This compressed air is passed through the nozzle and then they hit on the surface of rotar blade. The blade and unbalanced mass mounted on shaft can rotate at high speed to produce vibration. 1.2 MERIT OF VIBRATORS:- Pneumatic vibrator force power, frequency, amplitude, are not only easily changed but also can be adjusted while operating. Ideally on vibration test. The body is made of highly strength aluminum alloy. It is a well simple structure and small size with strong vibrating force. The damage to equipment will be minimized while suddenly power on/off. Moving by Air, easy operate no spark. They can be applied onto hazardous area or high humidity work environment Different vibration frequency types can meet with various requirement. 2. Material Used for Fabrication of Pneumatic Vibrator:- Mild steel is used for fabrication. Mild steel (iron containing a small percentage of carbon, strong and tough but not readily tempered), also known as plain-carbon steel and low-carbon steel, is now the most common form of steel because its price is relatively low while it provides material properties that are acceptable for many applications. Mild steel contains approximately 0.05–0.25% carbon making it malleable and ductile. Mild steel has a relatively low tensile strength, but it is cheap and easy to form; surface hardness can be increased through carburizing. Table -1: Chemical Composition Element Contents Carbon, C 0.14 - 0.20 % Iron, Fe 98.81 - 99.26 % (as remainder) Manganese, Mn 0.60 - 0.90 % Phosphorous, P ≤ 0.040 % Sulfur, S ≤ 0.050 % Low-carbon steels suffer from yield-pointrunout where the material has two yield points. The first yield point (or upper yield point) is higher than the second and the yield drops dramatically after the upper yield point. Ifa low-carbonsteel is only stressed to some point between the upper and lower yield point then the surface develops Lüder bands. Low-
