The objective of this research is to optimize the performance of the helical coil spring used in the suspension of cars of hatchback segment by varying different parameters of the spring to make it more efficient than the existing coil springs used in current hatchbacks. The helical compression spring utilized in mechanical system or shock may be a machine designed to free or damp shock impulse and dissipate mechanical energy. A helical compression coil spring which is used in four-wheel cars which are belonging in the hatchback category of the Indian automotive market. It is observed that the vehicle drifts towards one side due to the high weight of the suspension system and loads. This problem can be solved by redesigning and optimizing the suspension spring. This project consists of analytical methods and Finite Element Analysis completed from modeling, meshing, and post-processing of front su...

Main use of bagasse is for the power generation in sugar industry and as a fertili zer, but large amount of waste bagasse is generated from sugar industry. In view of this bagasse can be used as a raw material for the preparation of activated carbo n. Activated carbon were prepared from bagasse pith by a chemical activation with 14% H 3PO 4,Pre-carbonization and followed by pyrolysis at 800 °C by physical activation in absence of air. The Act ivated carbon has been employed as adsorbent for the removal of Methyl Orange dye solution. The nature of possible adsorbent and dye inte raction was examined by the SEM and EDAX technique. Batch experiments were carried out at various adsorbent dose, dye concentration & contact time for optimum condition.The adsorption of 100 ml dye solution (50 ppm) was found to be maximum (98 %) at contact time 40 minute and dosage of adsorbent3.5 gm. The extent of removal of Dye was fo...

The dielectric constant and loss have been measured as a function of frequency (100 Hz-1 KHz) and temperature (50°C to 300°C). Similar behavior is observed between dielectric constant and dielectric loss. Both dielectric constant and dielectric loss are found to decrease with increasing frequency. Photoluminescence (PL) spectra were taken at different excitation wavelength. PL emission spectra shows a broad spectra in the range 400 nm to 500 nm.
