Upgrading of An Existing Compact Water Treatment Plant Scientia Research LibraryJournal of Engineering And Technology Research2023114 Hinata pages :1-8 1 The four-point flexural behavior of specimens composed of textile-reinforced geopolymer mortar is investigated in this research. As reinforcement, two distinct mesh typescarbon mesh and basalt meshwith varying aperture sizes were employed. Only two mesh layers reinforced with geopolymer mortar are taken into consideration in this experimental effort (for each type of textile). The four-point bending strength of all 21 plate specimens, including reference specimens, which measure 360x180x20 mm3, has been examined. In addition, 15 samples measuring 30 x 30 x 150 mm3 and 15 samples measuring 45 mm in diameter by 90 mm in length have been tested in order to assess the mechanical characteristics of the geopolymer mortar matrix. According to the findings, specimens of geopolymer composites with carbon meshes exhibit greater flexural strength and deflection than those with basalt meshes. Additionally, by increasing the prescribed number of strands, the meshs flexural strength is greatly improved by decreasing its aperture size. Keywords: Geopolymer, four-point flexural strength, textile, compressive strength, carbon mesh, basalt mesh. http://www.scientiaresearchlibrary.com/archive-abs.php?arc=927http://www.scientiaresearchlibrary.com/archive/Examining Textile Reinforcements Four Point Flexural Behavior Experimentally in Geopolymer Mortar.pdf

Examining the Workspace Performance of a Multi-DOF Parallel Robot Manipulatorss Scientia Research LibraryJournal of Engineering And Technology Research2023114 Mngz, Qian pages:1-6 1 This paper proposes a parallel robot manipulator with five degrees of freedom (DOF). The 5-SPSUPU parallel robot manipulators kinematics, workspace, and dexterity performance were all methodically inferred. The stationary platform, five similar legs, a passive-constrained leg, the moving platform, and a few joints make up the suggested system, which has two rotations and three translations. Initially, the coordinate transformation theory and differentiation method were used to derive the inverse of kinematics and the Jacobian matrix. Second, the software uses the boundary search approach to examine the novel robots workspace. The robots posture and position workspace variations are analyzed numerically and reported. Third, an analysis of the suggested manipulators dexterity performance revealed that its best kinematic dexterity is 1.1. According to the analytical findings, the robot described in this study has a large effective workspace and dexterity, making it suitable for widespread use in the industrial robots area. Keywords: Parallel manipulator, kinematics analysis, workspace, dexterity. http://www.scientiaresearchlibrary.com/archive-abs.php?arc=928http://www.scientiaresearchlibrary.com/archive/Examining the Workspace Performance of a Multi DOF Parallel Robot Manipulator.pdf

Material Properties Impact on High Strength Steel Stampings Springback Scientia Research LibraryJournal of Engineering And Technology Research2023114 Kenzo pages:1-6 1 Material properties have a major impact on the parts springback during the stamping process. Additionally, research on the influence is required. Tensile strain hardening exponent (r), plastic strain ratio (n), and yield stress are the traditional material property indexes in question. This work used test design, FE analysis, and response surface analysis to examine the impact of yield stress, plastic strain ratio (n), and tensile strain hardening exponent (r) on the springback. As the yield stress and n value rise, so does the springback. A modest effect is also shown by the r value. Keywords: Springback, material property, high strength steel. http://www.scientiaresearchlibrary.com/archive-abs.php?arc=929http://www.scientiaresearchlibrary.com/archive/Material Properties Impact on High Strength Steel Stampings Springback.pdf
