We examine the southern Vietnamese site of Rach Nui, dated to between 3390 and 3850 cal BP, in context three major aspects Neolithic Mainland Southeast Asia: mound formation chronology, construction techniques, subsistence economy. Results indicate that this ca. 75 m diameter, 5 high mound, comprising over a dozen phases earthen platforms, upon which were raised sophisticated wooden structures, was built <200 years. While consuming domesticated millet, rice, occasionally dogs pigs, main...
Compliant mechanisms' design aims to create a larger workspace and simple structural shapes because these mechanical systems usually have small dimensions, reduced friction, less bending. From that request, we designed optimal bridge-type compliant mechanism flexure hinges with high magnification ratio, low stress by using joint, especially no friction This joint was dimensions for the studied method of grey relational analysis (GRA), which is based on Taguchi (TM), finite element (FEA)....
To achieve high work performance for compliant mechanisms of motion scope, continuous condition, and frequency, we propose a new hybrid algorithm that could be applied to multi-objective optimum design. In this investigation, use the tools finite element analysis (FEA) magnification mechanism find out effects design variables on ratio then select an optimal meet requirements. A poly-algorithm including Grey-Taguchi method, fuzzy logic system, adaptive neuro-fuzzy inference system (ANFIS)...
In manufacturing practice, manufacturers always strive to achieve both quality and productivity targets simultaneously. the first part, this study examines relationship between input factors, including cutting speed, depth of cut, feed rate, output response, which is surface roughness, when milling hardened SKD11 alloy steel under minimum coolant lubrication conditions using SiO2 nanofluid. The parameters are divided into four levels determine their influence on roughness find optimal for...
The tungsten inert gas (TIG) welding method most commonly used to weld ferrous metals, nonferrous and other metals since it is simple, easily implemented, achieves consistent high-quality welds. In this study, butt joints produced between aluminum alloy A6061-T6 stainless steel SUS304L have been achieved by using TIG with ER4047 filler metal. macrostructure microstructure of the resulting specimens were analyzed means an optical microscope (OM), a scanning electron (SEM), energy dispersive...
In metal cutting, surface roughness plays an important role in assessing the quality of processed products. The depends greatly on selection machining parameters such as cooling conditions and cutting parameters. For this purpose, including dry, MQL, Silica-based nanofluid MQL well speed, depth-of-cut feed-rate were investigated to determine their influence during hard milling AISI H13 steel. DOE method developed by G. Taguchi was used design experiments. An analysis signal-to-noise response...
The stress and deformation of the body frame chassis a coach subjected to bending, torsion, emergency braking returning must be considered during design manufacture passenger vehicles. model 29/34-seat in this investigation is newly designed vehicle based on old coach; most significant change has been chassis. It vital ensure it remains safe durable when operates road 4 cases mentioned above. Therefore, purpose study optimise maintain stable state structure by using Taguchi method grey...
The steering system in the car assumes task of navigating when is motion. It not only plays a technical role but also performs crucial vehicle safety. In this study, model with helical gear and incline rack was created by Solidworks. And maximum principal stress, strain were determined finite element analysis ANSYS. data simulation used to minimize stress Taguchi method based on grey relational analysis. results indicated that input variables have significantly affected rack. then problems...
The purpose of this research indicates the experimental results Metal Inert Gas (MIG) welding process butt joint between A5052 alloys and SS400 steel using ER4043 filler metal. mechanical properties joints were investigate. analysis shows that intermetallic compound layer appeared at interface seam with their width increasing from 3.106 μm to 4.929μm maximum micro-hardness IMCs reached 850HV.
Welding dissimilar materials has been widely applied in industries. Some of them are considered this as a strategy to develop their future technology products. Aluminum alloy and stainless steel have differences physical, thermal, mechanical metallurgic properties. However, selecting suitable welding process rods can solve problem.
