Title	:	Design and Modeling of Passive Hydro-pneumatic Suspension System for Car
Country	:	India
Authors	:	M. B. Darade || N.D. Khaire

Abstract: Suspension system is most important in a vehicle which counters the disturbances generated from the road. It contributes significantly on the vehicle's stability, safety and control. The hydro-pneumatic system uses an accumulator to generate spring force and a remote valve block to generate damping force. A hydraulic cylinder replaces the damper strut and springs of the vehicle. The cylinder generates oil volume displacement towards the accumulator....

Abstract: Mechanical springs used in any machine hold its own stiffness value. This stiffness/ spring rate changes according to different springs and its application. Stiffness of any spring is an important factor as far as its application is considered. Hence in industries many methods are used to test and calibrate springs. Many methods are been used to test springs such as hydraulic actuators or by applying external load etc. In search of the most advanced machinery to test springs, basic mechanisms are under looked. This leads to inefficient growth of machines..........

Abstract: In many structures, cracks may appear during manufacturing process or in service. Stress intensity factor is used in fracture mechanics to more accurately predict the stress state (stress intensity) near the tip of the crack caused by remote load or residual stresses. In this work a rectangular plate with central hole & two cracks emanating from his hole is analyzed for remote tensile loading. Stress Intensity Factor is determined for this configuration using finite element based software ANSYS....

Title	:	Design Optimization of Shell an Tube Heat Exchanger for Tube Failure Prevention
Country	:	India
Authors	:	S.O. Rathi || S.H. Gawande

Abstract: In this paper a simplified approach to optimize the design of Shell Tube Heat Exchanger [STHE] by using Finite Element Analysis [FEA]. The FEA of STHE helps in achieving optimization in design by prevention of tube failure caused due to FEA.The main reason for design of STHE is to optimize the heat exchanger for safer design. Firstly, take the detailed design from Alfa-Laval (India), Ltd., Pune-10. then make the model in 3-D software and convert this model into ANSYS for analysis and after these calculate the stress strain value by using numerical method. These shows that software and numerical stress, strain values are same therefore design is safe, also find frequencies at different modes.

Abstract: Structural vibration problems causes major hazards and design limitations of a very wide range of engineering products. The Cooling tower fan blades are exposed to severe conditions of excitation and vibration during their service life, thus it may have an effect on their dynamic behavior and this leads to structural damage that is the failure of cooling tower performance severely. The vibration stresses causes the severe threat to the operation of Fiber Reinforced Plastic (FRP) fans..
