In this technique, comparison between actual natural frequency (without crack) and frequency due to crack propagation is made using Euler Beam theory. When cracks are present in structure, natural frequency of material deviates from its original frequency and result difference will measure in term of crack. Whole analysis procedure starting from modelling, meshing and result interpretation done on well-known numerical tool ANSYS. The main aim of proposed study is to detect critical areas especially crack initiative zone before doing actual fabrication of components and avoid the breakage of it. Effects of a breathing crack on the vibratory characteristics of a rotating propeller shaft are investigated. Results of numerical Finite Element Method (FEM) are validated using experimental apparatus called acoustic emission technique.

Tests were conducted for three different compression ratios. Engine test setup was developed with moving cylinder head for variation of compression ratio to perform investigations using these blends. The engine performance studies were conducted with rope break dynamometer setup. Parameters like speed of engine, fuel consumption and torque were measured at different loads for pure diesel and for blends of diesel with ethanol at different compression ratio. Break Power, BSFC, BTE and heat balance were evaluated. Paper represents the test results for blends 5% to 20% and three different compression ratios.

Specific work output, thermal efficiency and SFC is simulated with respect to operating conditions. Analytical formulaes were developed taking into account the effect of operational parameters like ambient temperature, compression ratio, compressor efficiency, turbine efficiency, regenerator effectiveness, pressure loss in inter cooling, reheating and regenerator. Calculations were made for wide range of parameters using engineering equation solver and the results were presented here. For pressure ratio of 12, regenerator effectiveness 0.95, and maximum turbine inlet temperature 1200 K, thermal efficiency decreases by 27% with increase in ambient temperature (278 K to 328 K). With decrease in regenerator effectiveness thermal efficiency decreases linearly. With increase in ambient temperature (278 K to 328 K) for the same maximum temperature and regenerator effectiveness SFC decreases up to a pres...

The literature review reveals that the exhaust gas noise level depends upon various factors. Muffler geometry, extension in inlet and outlet valves, number of whole perforations and its diameter are the factors which affects noise from engines. The objective of this study is to reduce exhaust gas noise level. The performance of the muffler is assessed by analyzing pressure variation, exhaust gas flow pattern, length of expansion chamber, transmission loss. The K-epsilon method is used to obtain desired outputs by inputting sinusoidal nature of pressure wave. The modeling of muffler is done by using modeling software CATIA V5 and performance parameters are estimated using Star CCM+ software. This study helps to improve reduce the noise level and environmental noise pollution. The results obtained from software are compared with analytical method and they are found close agreem...

To develop suitable welding models, we must consider the process parameter (welding speed, Heat flux, Gap and Temperature), the geometrical constraints, the material nonlinearities and all physical phenomena involved in welding. Therefore it is a great challenge to consider all factors at the same time, so generally the models include some approximations: in the works, we can find some attempts to reduce modelling efforts, and Reduces Residual stress in welding.

The commercial finite element package CATIA version 5 was used for the solution of the problem. To reduce the expenses of the chassis of the trucks, the chassis structure design should be changed or the thickness should be decreased. Also determination of the stresses of a truck chassis before manufacturing is important due to the design improvement. In order to achieve a reduction in the magnitude of stress at critical point of the chassis frame, side member thickness, cross member thickness and position of cross member from rear end were varied. Numerical results showed that if the thickness change is not possible, changing the position of cross member may be a good alternative. Computed results are then compared to analytical calculation, where it is found that the maximum deflection agrees well with theoretical approximation but varies on the magnitude aspect.

moderate solid concentration, velocity, and particle size and impact angle. A slurry pot t is then
fabricated by inserting propeller from the bottom of the cylinder and is rotated at the speed required for
uniform distribution. The test specimens are then mounted on test fixture which is fixed and has a
provision to move in different angular position to find out the wear for different angles. Erosion of
materials is occurs due to the impact of high velocity of slurry which is comes out from the nozzle and
impacting on the test specimen. Two different experiments are conducted preliminarily first for
repeatability test for fix parameters such as angles from 150 to 900 in six intervals of 150
difference,particle size 655micron, and 10% solid concentration for 120 minutes The results were
obtained for ductile material and are found in good arrangement with the literature.
