Design and Analysis of Two Spindle Amber Charkha- A Review

The Charkha is a small device which can be used to spin fiber, such as cotton, into yarn. Fabric from this yarn can be used to make all sorts of clothing. Increasing demands of the cotton fabrics, now a days, has made it necessary to increase the production of cotton fabrics. To increase the production it is necessary to study the factors affecting the performance of the women workers working on Amber charkha. Most of the Amber charkha in rural areas are hand operated (i.e. they run with the help of human energy input). This paper highlights some of the factors which are responsible for their performance. The various factors that are affecting the productivity are technical factor, their weight and cost of the two spindle amber charkha. Each of these factors plays an important role in the overall performance of the workers. The detailed study is carried out to design and analysis of two spindle of Amber charkha. The basic necessity of this study is to minimize its weight and price which would help the workers for achieving better productivity with work satisfaction

ENHANCEMENT OF SURFACE ROUGHNESS OF 316L STAINLESS STEEL AND TI-6AL-4V USING LOW PLASTICITY BURNISHING: DOE APPROACH

ABSTRACT In the present work, effect of Low Plasticity Burnishing (LPB) parameters in improving surface roughness of 316L Stainless Steel and Ti-6Al-4V have been investigated. Full factorial design of experiment (DOE) have been used to visualize the effect of LPB process parameters such as speed, pressure, ball diameter and number of passes on surface roughness. The signal-to-noise (S/N) ratio and ANOVA was carried out to identify the significant LPB parameters. The percentage improvement in surface roughness is found to be 87 % and 85 % for Ti-6Al-4V and 316L Stainless Steel respectively. Empirical relations have been developed for LPB parameters and the surface roughness

Design Optimization of C Frame of Hydraulic Press Machine

This paper attempts to acquire the FEA implementation for analysis and design optimization of C Frame of 100 ton Hydraulic Press Machine. Availability of limited resources for profit oriented manufacturing industries forces optimum use of available overall resources with a basic intention of cost saving approach. Design of a hydraulic press structure is of prime importance keeping in mind the design parameters and performance indicators and their relationship with proper knowledge of existing working conditions and application of load. By FEA implementation, attempts are being made to reduce the thickness of the plates for the C frame structure in order to save the material and its cost

Design, Development and Analysis of the Roll Cage for All – Terrain Vehicle

We have tried to design an all terrain vehicle that meets SAE INDIA standards and is also cost effective at the same time. In the present investigation, the performance of ATV roll cage is studied against crashes that can be encounter in the real life scenario and its consequences on the individual components. The roll cage structure which must be designed to ensure the safety of the driver while not compromising the ergonomics. The roll cage not only forms the structural base but also a 3-D shell surrounding the occupant which protects the occupant in case of impact and roll over incidents. The roll cage also adds to the aesthetics of a vehicle. The design and development comprises of material selection, chassis and frame design, cross section determination, determining strength requirements of roll cage, stress analysis and simulations to test the ATV against failure using 1 Dimensional Analysi

Review Paper on Free Vibration Response of Magnetorheological Elastomer-based Sandwich Beam

The dynamic analysis of a three-layered symmetric sandwich beam with magneto rheological elastomer (MRE) embedded viscoelastic core and conductive skins subjected to a periodic axial load have been carried out under various boundary conditions by researchers. As the skins of the sandwich beam are conductive, magnetic loads are applied to the skins during vibration. Due to the field-dependent shear modulus of MRE material, the stiffness of the MRE embedded sandwich beam can be changed by the application of magnetic fields. Using extended Hamilton’s principle along with generalized Galarkin’s method the governing equation of motion has been derived. The free vibration analysis of the system has been carried out and the results are compared with the published experimental and analytical results which are found to be in good agreement. Here, recently developed magneto rheological elastomer based on natural rubber containing iron particles and carbon blacks have been used. The effects of magnetic field, length of MRE patch, core thickness, percentage of iron particles and carbon blacks on the regions of parametric instability for first three modes of vibration have been studied. These results have been compared with the parametric instability regions of the sandwich beam with fully viscoelastic core to show the passive and active vibration reduction of these structures using MRE and magnetic field
