OPTIMIZATION OF WALL MATERIAL FOR MINIMUM HEAT LOSSES FOR INDUCTION FURNACE BY FEA
Get PDFInduction furnaces are commonly employed for melting metals, and to prevent losses, silica ramming mass is typically used as a refractory material. Consequently, it is crucial to optimize the thickness of the refractory material. This research paper focuses on optimizing the wall thickness and material to minimize heat losses during the iron melting process. Calculations involve determining thermal properties and physical parameters for heat loss calculations. Theoretical heat loss and temperature distribution calculations are then compared to actual measurements obtained from an existing furnace, which experiences significant losses. To perform the optimization, ANSYS Software was utilized, providing more accurate results in a shorter timeframe. The problem was approached in an axi-symmetric manner since it exhibits symmetry about the Y-Axis. Ultimately, it was concluded that optimizing the thickness of the refractory material could reduce losses by 35%, while optimizing the thermal properties could lead to a reduction of 73% in losses. By employing the proper thickness and material properties for the refractory material in the induction furnace, losses can be ultimately reduced by 70%.
 
Influence of Relative Stiffness on Bending Moment in Raft Foundations
Get PDFThis research article delves into the impact of raft and soil stiffness on the seismic behavior of soil-structure systems. Understanding soil-structure interaction under seismic loading is crucial for designing and analyzing structures in earthquake-prone regions. The stiffness of both the raft and the underlying soil significantly affects the dynamic response and overall performance of the system. To achieve the research objectives, an extensive numerical study employing advanced finite element analysis is conducted. Various scenarios are explored by systematically varying the stiffness properties of the raft and soil. The seismic response is assessed through structural displacements, accelerations, and stresses, as well as soil settlement and lateral soil pressures. The study\u27s findings highlight the noteworthy influence of raft and soil stiffness on the seismic response of soil-structure systems. Higher raft stiffness tends to reduce structural displacements while increasing stress levels in the structure. On the other hand, softer soil stiffness amplifies the structural response, resulting in larger deformations. The outcomes of this research provide valuable insights for designing and optimizing soil-structure systems subjected to seismic forces. Engineers and researchers can utilize these findings to enhance the seismic performance of structures by appropriately selecting and adjusting the stiffness of the raft and soil, while considering site-specific conditions and design requirements

Design Development & Analysis of Dual Mass Flywheel Spring
Get PDFAll engines have flywheels or weighted crankshafts that balance out compression and power strokes, maintain idle speed, aid starting and reduce parts wear. Dual mass flywheel is a multi-clutch device which is used to dampen vibration that occurs due to the slight twist in the crankshaft during the power stroke. The torsional frequency is defined as the rate at which the torsional vibration occurs. When the torsional frequency of the crankshaft is equal to the transaxles torsional frequency an effect known as the torsional resonance occurs. When the operating speed of the engine is low, vibration occurs due to the torsional resonance and this can be avoided using dual mass flywheel Spring. This work is carried out to study the effect of arc springs on the dual mass flywheel. The main aim is to increase durability of the arc spring and to elimination of gear rattle.

Analysis of Turning Radius of Truck to Describe Yaw-Moment Control
Get PDFThis paper presents an investigation into the turning performance of a vehicle implementing direct yaw-moment control to effectively reduce the turning radius. The proposed approach involves turning the rear wheels in the opposite direction of the truck, resulting in a yaw-moment around the vehicle\u27s centre of gravity. This yaw-moment enables the vehicle to execute tight turns. In comparison to traditional Ackermansteered vehicles, the differential-steered method offers advantages due to its simpler structure. Based on the calculation, a comparative analysis was conducted between the 4WS (fourwheel steering) and 2WS (two-wheel steering) configurations of the Eicher Pro 3015 truck. The calculated turning radius for the 4WS configuration is 5.01 meters, while the standard 2WS configuration has a turning radius of 8.659 meters. This indicates that the 4WS configuration allows for a smaller turning radius compared to the 2WS configuration, enabling the truck to maneuver more easily in confined spaces and navigate tighter turns. 2WS configuration has an angle of 21.9 degrees. This signifies that the 4WS configuration provides a reduced angle of turning, allowing the truck to execute sharper turns and enhance manoeuvrability. As per the comparative analysis of the turning radius and angle of turning, it can be concluded that the 4WS configuration of the Eicher Pro 3015 truck offers superior maneuverability compared to the standard 2WS configuration. The 4WS configuration provides a smaller turning radius and a reduced angle of turning, indicating enhanced agility and improved performance in various operating conditions. This makes it more suitable for applications that require precise and efficient navigation, such as tight urban areas or construction sites
