WEAR CHARACTERISTICS OF 3D PRINTED PLASTIC GEAR WITH DIFFERENT INFILL PERCENTAGES Daing Nafiz, M. A. H. Rasid, Ahmad Fitri, Santosh Patil, M. Sadiq A. Pachapuri Composites Mechanics Computations Applications, 2023 Polymer gears have great potential in motion and power transmission since they offer many advantages over conventional metal gears. However, the use of polymer gears in industrial applications has been limited due to inadequate information with respect to their performance and designs. In this research work, our goal was to study and analyze the characteristics of a polymer gear produced from polylactic acid through the a three-dimensional (3D) printing process. Experiments involving polymer test gears were carried out on a test rig at three rotational speeds. The parameters studied during the investigation were the infill percentage, rotational speed, and load attendance. Four types of failure characteristics-namely, the formation of debris, micro-surface condition monitoring, weight loss, and thermal damage-were analyzed in the experiments. The investigation showed that the weight reduction wear rate was related to the development of debris and the condition of the gear. The test gear wear rate from the weight reduction through material scratching and breakage increased progressively under extreme wear conditions. Further thermal analysis and microstructure observations also revealed the impact of temperature from frictional heat on the amount of wear on the polymer gear. The higher the operating temperature, the higher was the amount of wear seen in the polymer gear.
Response surface modeling for optimization of ring-stiffened polymer composite pressure hull Nagaraj Kishor Kelageri, Deepak C. Patil, M. Sadiq A. Pachapuri, Ravi Lingannavar Composites Mechanics Computations Applications, 2021 Buckling failure of ring-stiffened composite pressure hulls is a key consideration in the design of submarine structures. The paper presents mathematical modeling of collapse pressure for the overall buckling of stiffened carbon/epoxy composite pressure hull subjected to hydrostatic pressure using the response surface model. The key parameters considered for the study are volume fraction, number of stiffeners, shell thickness, ring width, and ring height. Total 41 experiments were conducted as per the Box-Behnken design. Calculation of collapse pressure is done using the finite element method (FEM). The linear models were developed to predict the mass of the pressure hull and the collapse pressure due to overall buckling. Further, the design optimization of the pressure hull has been carried out to make the structure lighter in weight and stable at target hydrostatic pressures using the simplex algorithm. Results showed a 9 to 14% reduction in mass compared to plain cylindrical pressure hulls.
Design and analysis of lower control arm of suspension system M. Sadiq A. Pachapuri, Ravi G. Lingannavar, Nagaraj K. Kelageri, Kritesh K. Phadate Materials Today Proceedings, 2021 In automotive suspension, a control arm is a hinged suspension link between the chassis and the suspension or hub that carries the wheel. The chassis end of a control arm usually rubber busing, is attached by a single pivot. It controls the position of the tyre end in only a single degree of freedom, maintaining the radial distance from the chassis mount. The single bushing does not control the arm from moving back and forth; this motion is constrained by a separate link or radius rod. Wishbones are triangular and have two widely spaced chassis bearings, which constrain the tyre end of the wishbone from moving back and forth, controlling two degrees of freedom, and without requiring additional links. Most control arms form the lower link of a suspension with few designs using them as the upper link, usually with a lower wishbone. The lower arm should be sturdy, in many cases reported by the users of a particular vehicle, fluttering noise heard over the humps. This paper calculates the forces acting on the lower arm of a four-wheeler with critical loading conditions as the Finite Element Analysis carried for the McPherson type suspension system. The static analysis performed to determine the location of maximum deflection and stress distribution while the vehicle is stationary and moving over the hump at different speeds. The free-free and constrained modal analysis performed on the suspension arm to find the natural frequency. The fatigue analysis performed to find the life of the arm. Further, by performing topological optimization leads to reduction in the weight.
Influence of process parameters of electrical discharge machining on MRR, TWR and surface roughness: A review Sachidananda Taddalase Ganapati, M. S. A. Pachapuri, C. V. Adake Aip Conference Proceedings, 2019 Electrical Discharge machining (EDM) is a nonconventional machining technique, which has been commonly used to create dies and mold. Harder Materials can be machined into complex shapes as long as they conduct electricity. Recent advances in the technologies brought the development of new engineering materials, which are hard to machine with traditional machining processes. EDM is capable of machining these materials; given these materials have an adequately high electrical conductivity. In EDM, Material removal rate (MRR) Tool Wear rate and surface roughness (Ra) are important performance measures. Numbers of ways are explored by researchers to improve and optimize MRR along with a reduction in tool wear rate (TWR) and surface roughness (Ra). This paper discusses researches on EDM, involving the enhancement of MRR in conjunction with a little insight into material removal mechanism.Electrical Discharge machining (EDM) is a nonconventional machining technique, which has been commonly used to create dies and mold.
