Abstract:- This project-foldable Mobike is developed to make the automobile a more Eco friendly vehicle and to reduce the problems of parking. It consumes less fuel when compared to other ordinary bikes available. This bike is more useful at the time of breakdowns, The Provisions are made in such a way that the bike can be folded and an arrangement of a link helps to fit this folded bike like a trolley which can be rolled anywhere. The folding mobike originally developed for the use in times of breakdowns, traffic jams etc., and since it is portable it can be carried on top any place. This type of bike consists of mainly a folding arrangement and a folding suitcase.
For avoiding torsional vibrations, dampers are catered in antonym terminal. Thus the performance of engine depends upon the efficiency, power and weight of crankshaft. Efficiency should be high, weight must be low and power to transfer should be certainly high. Key factor in determining the life of engine is stress computation. In the past beam and space chassis were used but as it contains minimal nodes it become cumbersome for calculations so new technique (finite element analysis (FEA) was adopted to make calculation simpler.
Higher capacity for same size rotors and same rpm as profile is cut more deeply. 3. Ability of rotors to withstand rotor contact without problems for oil injected screws, due to small relative motion between the rotors where contact occurs. This means we do not need timing gears. 5.2.2.
For this reason, in most cases, NCGs are not round, but round NCGs looking like regular gears is also possible (small ratio variations results from meshing area modifications). Generally, all the requirements of regular gearing should be met by NCG, but in few cases, for example variable axle distance, could prove impossible to support. Such gears require very tight manufacturing tolerances and assembling problems arise. Due to the complicated geometry, NCGs are most likely spur gears and molding or electrical discharge machining technology is used instead of
The concept where gears decrease the speed of the vehicle but increase its torque is called as gear reduction. External Structure The outside structure of a DC geared motor looks as a straight extension over the simple DC motor. The side view of the motor shows the external protrudes of the gear head. A nut shaped metallic ring is placed near the shaft which helps in attaching the motor to the other parts of the assembly. • IC Lm293d IC LM293d is motor driver that is used to drive the motor clockwise or anticlockwise.
The ends of the bar are connected to an end link through a flexible joint. The anti- roll bar end link connects in turn to a spot near a wheel which transfers forces from a heavily loaded axel to the opposite side. So in anti- roll bar forces are transferred from heavily loaded axle to the connected end link via a bushing, to the anti- roll bar via a flexible joint to the connected end link on the connected end link on the opposite side of the vehicle to the opposite
In addition, epoxy glue is used to fix the magnets to the rotor surface in the inset and projecting surface-mounted machines. This implies that the mechanical strength of the surface mounted machines is only as good as that of the epoxy glue, assuming no retaining sleeve is used; hence, buried PM machines are more robust and tend to be used for high-speed
The grains of the workpiece get elongated in the direction of the process. Figure 2.1 Rolling Process Slab (free body equilibrium) Method Rolling of plates and sheets is essentially a plain-strain compression because the length of contact between rolls and work piece, L, is usually much smaller than the width of the sheet, w as shown in the Figure 2.1.1.The initial height is h0 and final height is hf. As the plastic region is thinned by the compressive stress, σz, it is free to expand in the rolling direction, x. However lateral expansion in the y-direction is constrained by the undeforming material on both sides of the roll gap. The net effect is a condition of plane strain, εy = 0 and εz = −εx, except at the edges.
The spindle is rotated with mechanasim envoloped through a calibrated spring. The spring’s viscous drag offored by the resin against the spindle is measured by its deflection which in turn and calculated by transducor . Viscosity is measured in units of centipoise. Procedure:- The Viscometer is auto zeroed by removing the spindle and pressing any key. Set speed as designated in product specification.
1. LITERATURE REVIEW 1.1. INTRODUCTION Many researchers all over the worldwide examine the issue of waste water sludge resulted from WWTPs and introduce many solutions to dispose this sludge in an easy, cheap and safe way without harm the humankind, they examine many ways like utilizing the sludge in (landfill, incineration, and Sustainable Agricultural Use), but these ways had a destructive impacts for the humankind, and the environments too. Hence, the researchers try to discover and create better approaches to overcome these issues; one of these solutions is utilizing the dry sludge with different percentages in many construction materials like (non-reinforced concrete, brick, and glass). 1.2.
