The aim of this Kinematics Based on Four Bar Linkage BE Mechanical Seminar Topic & Project Report is to make a four bar linkage and display the movement by a hand crank. Based on rubric with five other legs, there is no need to turn, efficient and display analysis and calculations of the outermost point of linkage.

The four-bar linkage is a movable and simplest linkage. It includes four rigid bodies known as bars or links. These are connected by pivots to produce a closed loop. Four-bars are the common mechanisms in mechanical engineering and kinematics. The pivot joint includes one rotational degree of freedom and mechanism is planar.

The planar four-bar linkages include many different motions based on calculations. Many mechanisms include movable members and these motions form trajectories points on the mechanism. The link is rigid in every mechanism which acts like a frame.

Inversions mechanisms are configurations with manipulation of the rigid link known as frame. The data from one link is utilized to know about other inversions. Inversion technique is used for mechanisms synthesis and analysis.

There are two kinds of joints based on contact type. They are lower pair joint and higher pair joint. Lower pair joint is contact of area among two mating surfaces whereas higher pair joint is link among mating surfaces like line contact.

Conclusion:

The Kinematics Based on Four Bar Linkage BE Mechanical Seminar Topic & Project Report concludes that the constant body is known as ground link which is required to get every position. There are two links linked to the ground are known as grounded links and the left link is known as coupler link. The second grounded link is the follower link.

This Influence of Shape of Directrix on the Cost of RC Cylindrical and Conoidal Shells Mechanical Engineering project & Seminar Topic is based on the Cylindrical and Conoidal shells. There are few kinds of cylindrical and conoidal shell. They are Circular Directrix, Parabolic Directrix, Inverted catenary Directrix, and Cycloidal Directrix.

 Shells space roofs are made for plane roofs because these roods cover major floor spaces and utilizes construction materials. The curved space roofs need materials of about 25 to 40% rather than plane elements. The shell roofs are major one because cross section is stressed with direct forces and bending effects. Based on this, shells thickness is very less ranging between 75mm to 150mm.

 The shell structures are very costly. Economically, thin shell roofs are competitive with many same units. The form works cost builds shell roofs costly rather than cement and steel. The costs of form work are made based on precasting mobile forms. The benefits of shell roofs are aesthetically superior, material used is very less, form work is deleted in the starting, and high column free areas are covered.

 Cylindrical shells are the shell structures due to span up to 45m with less material need. They are important structures since it is made by arch forms to remove thicknesses and stresses in the transverse way. The conoid surface is created with movement of straight parallel to a rigid plane.

 Conclusion:

 The project concludes on the shell roofs which are used for sport auditorium, exhibition halls, hangers, industrial buildings and many span structures. The roofs are very costly and utilized for domes by Romans. The advances like the shell structures make use of prefabricated shell elements.

This Independent Suspension System Dept of Mechanical Engineering Final Year Project presents the independent suspension which deals about the automobile suspension system providing the wheels to move in the vertical position. The movement depends on live axle and beam axle that affect both the wheels. The left and right suspension spring are tied by anti-roll bar. Many vehicles possess independent front suspension (IFS) and independent rear suspension (IRS). IRS includes rear wheels sprung.

 The important thing for lower unsprung weight is for driven wheels. The motion between the wheels and the differential is by using swinging drive shafts linked by universal (U) joints and analogous to the constant-velocity (CV) joints.

 Vehicle dynamics is defined as the forces provided on a movable car. There are two views considered by automobile engineers for moving car are RIDE and HANDLING. Ride is the ability of a car to move on a rough road and handling is ability of a car to drive safely brake, accelerate, and corner.

 There are four kinds of suspension. They are conventional suspension system, independent suspension system, air suspension system, and hydro-elastic suspension system.

 The system has no reaction on steering. It needs major distance to stop rolling action. The front axle provides better road holding tendency of tyres. There is less vibration. It offers smooth ride and rear wheels are stable.

Conclusion:

Typically, the project on independent suspension systems provides the good ride characteristics and quality because of lower unsprung weight. IRS makes the wheel to jump on a hard land. The system needs expenses and engineering effort for live axle arrangement. IRS offers great manufacturing rates.

The Hydraulic Pumps and Pressure Regulation Mechanical Engineering Project is about the hydraulic pump that gets the oil from a tank and gives to the hydraulic circuit by increasing oil pressure to the particular level. The pumps are moved at constant speed with the help of AC induction motor that rotates at 1500 rpm. The motor and pump are used as a one unit.

 There are two types of pump and compressor where one is used for fluids and another one for gases. Fluid is moved into the pump and thrown out of periphery with the centrifugal force. The fluid flow keeps the pressure at the end of pump. The devices are called hydrodynamic pumps applied to transmit the fluid from one place to another at low pressures.

The pump transfers the rigid volume of fluid at the outlet port from inlet to outlet. The piston pump is without inherent pressure decided by leakage of pump. If the pressure is present into a dead end then the pressure increases with pump stroke continuously.

Pump data sheets need speed of 1200, 1500 or 1800 rpm based on the speed of induction motor. The capacity of pump depends on the drive speed and it is decreased and its efficiency decreases with the increase in fluid leakage. This is called slippage.

Conclusion:

Hydraulic pumps are hydrostatic that need concept to manage the system pressure to prevent pump failure or catastrophic pipe. The pump is designated with the delivery of flow rate and the pump could hold with high pressure. These are known as pump capacity and pressure rating.

This MAGNETIC BRAKING SYSTEM Mechanical Technical Presentation introduces the magnetic braking with the help of simple theory, law of Faraday and Lorentz force. The magnet is lifted and dragged forcibly on the dipole of magnet on a nonmagnetic plane depending on equations of Maxwell.

In the last few years, the magnetic braking has become very popular. The magnetic braking functions based on law of Lenz and induced currents. On comparing the metal plate with pendulum, its speed reduces on going through among magnetic poles.

If plate is in the file of magnet then electric field gets induced in the metal and hence producing currents. The current is opposite to the flux by the plate based on Lenz’s Law. The currents heat the plate by decreasing the kinetic energy. This aspect is used to apart nonmagnetic metals from solid waste and to remove vibrations in spacecrafts.

The magnetic drag force is very tough to obtain on the motion of metal object and equation of Maxwell. The rectangular sheet is checked on the linear motion by the magnet and hence rectangular sheet of magnetic braking is also checked based on linear motion of the magnet.

The sheet speed is small and magnetic field is produced by the induced current and it is negligible with the application of magnetic field. The magnetic drag force increases with mutual coupling among magnetic field and induced current.

Conclusion:

This MAGNETIC BRAKING SYSTEM Mechanical Technical Presentation has introduced about the magnetic lift force and magnetic drag force with the motion of magnets. Based on these forces, the magnetic levitated vehicles are manufactured with high-speed transportation.
