DESIGN AND STATIC ANALYSIS OF THREE AXIS PNEUMATIC DUMPER

Modern 3 ways dropping dumper’ has been conceived by observing the difficulty in unloading the materials. The survey in this regards in several automobile garages, revealed the facts that mostly some difficult methods were adopted in unloading the materials from the trailer. This paper has mainly focused on above difficulty. Hence a prototype of suitable arrangement has been designed. The vehicles can be unloaded from the trailer in three axes without application of any impact force. The Direction control valve which activates the ram of the hydraulic cylinder which lifting the trailer cabin in require side. Further modifications and working limitations will put this work in the main league of use. This concept saves time & energy which leads to efficient working.

In this paper the author presents a wheel loader equipped with side dump bucket modelled with modern technologies used in mechanical engineering fields (SolidWorks, Femap and NX 11 manufacturing). The various behaviours that acting on the bucket during technological process were analysed with finite element method. The obtained results validate appropriate dimensioning of main elements of bucket ensemble in proposed constructive variant.

Our main project is three axis pneumatic modern trailer works on the principles of pneumatic mechanism along with micro controllers. In this project the efficiency of dumping trailers will increase. The unloading of materials can be done to the three directions. This is very useful in the shipping industry. We are choosing this project for the decreasing the man power and time. The combination of pneumatics and micro controllers can be seen in our project. We have chosen this project because of the various attractiveness of pneumatics.

Mechanical design and fabrication of a lifting mechanism of a dumper truck. The project was motivated by a need to create a device that would bring about change in mechanism of lifting pre-existent in the world. As from past we have seen usage of hydraulics to lift load in dumper truck we aspire to minimize cost significantly by using pneumatic actuator coupled with bevel gear mechanism and open a new genre for research and development. The first and foremost problem faced was that a pneumatic cylinder works at about 6 times less pressure range and consequently lifts fewer loads when applied directly. But the same can be tackled when we make a single cylinder pneumatic engine and couple that shaft with a bevel gear having tooth ratio 16:10 on one end and thus protrude a threaded rod along which dumper moves up and down. Basically on the edge of dumper we attach a nut for movement laterally on the threaded rod and provide clearance of 0.5 feet to cover up the distance by which it ascends on the threaded rod. The model made is of 4 feet by 2 feet (lxb) capable of lifting 62 kg at an angle of 26.5 degree. To top it all off we are doing it all wirelessly combining it with a Flysky FS-CT6B 2.4 GHZ 6 channel Transmitter receiver and phoenix board that is used in aircraft wireless system powered by two 12 V battery connected in series with each other.

Pneumatic conveying system is a conventional material handling system like belt conveyor or chain conveyor. The main advantage of pneumatic conveying system is that material is transferred in close loop, thereby preventing the environmental effect on the material and vice versa. In these topic different parameters like air velocity, pressure, particle size and shape, distance to be conveyed, which govern the design of the system, are described. The research work carried out on the pneumatic conveying system in the last decade considering these parameters are also presented. No standard procedure is available for the design of pneumatic conveying system. As the configuration of the system changes, variable involved also changes, and one has to change the design considerations based on the applications. So there is wide scope for experimentation in the field of pneumatic conveying system.

— The fundamental multi-level auto stopping framework with three stories is considered to demonstrate the utilization of programmed or manual in stopping frameworks. The programmed or manual will assume a noteworthy part in sorting out the section to and exit from the parking areas. It likewise shows the plan of multi-level parking areas which possesses less need on the ground and contains the huge number of autos. In the present day world, where parking spot has turned into a major issue, it has turned out to be vital to maintain a strategic distance from the wastage of space in current enormous Automatic multi-level auto stopping framework limits the auto stopping territory organizations and lofts. The parking garages have a lift to convey autos to various floors as indicated by the opening.

The project being complicated was decide to be developed on a small scale model that should be constructed using light weight material and should be pneumatically operated using pneumatic cylinder arrangement. Also this pneumatic piston and cylinder arrangement was decided to be motor driven to make the same automatic. These motor run using a battery/ S MPS and are controlled using a remote control that is attached with the base model using wires / FRC cable and these after controlled by operator. Index Terms-S MPS , PTT, FRC.

Compressed air as a source of energy in different uses in general and as a non-polluting fuel in compressed air vehicles has attracted scientists and engineers for centuries. Efforts are being made by many developers and manufacturers to master the compressed air vehicle technology in all respects for its earliest use by the mankind. Nowadays, almost every industry is trying to develop light and efficient vehicles. Today, all the the vehicles running on conventional & non-conventional fuels are known for producing a large amount of harmful gases like CO 2 , SO 2 , NO 2 , etc. which acts increases global warming. The motto of our project is to design & fabricate vehicle running on air pressure for material handling in industries and reduce power consumption. It is rear wheel drive. We develop the concept of pneumatic vehicle from pedal operated tricycle. The vehicle looks like three wheeler in which manual operation is replaced by compressed air pressure. The following report gives a brief description of how a compressed air vehicle using this technology was made. While developing of this vehicle, control of compressed air parameters like temperature, energy density, requirement of input power, energy release and emission control have to be mastered for the development of a safe, light and cost effective compressed air vehicle in near future.

Hydraulic Excavators are heavy duty earth mover consisting of a boom, arm, bucket and cab on a rotating platform. It works on the principle of hydraulic fluid, with hydraulic cylinders and hydraulic motors. Excavator is subjected to resistive forces which are depends upon the terrain condition. These forces are unpredictable and dynamic in nature which damages the excavator component. Hence it is essential for designer to provide equipment with maximum strength, minimum weight and cost while maintaining maximum reliability and critical factor of safety. Along with this, the geometry of motion, irrespective of causes of motion also important for excavator. For obtaining optimum design, finite element analysis of excavator parts are essential. Also, for obtaining optimum motion of parts with respect to frame of reference, kinematic analysis of excavator is necessary. This paper depicts importing and meshing of CAD model of bucket and lower arm of excavator and its finite element analysis for strength and deformation evaluation. Also this this paper covers the kinematic analysis of whole assembly for understanding the behavior of the various joints which are used for connecting the parts of excavator.
