Abstract

Experiment is looking at the influence of dimensions, heat treatment temperature and cooling media effect linearly on hardness, tensile strength steel AISI 4140 so that the level comparison of the hardness of influence on the diameter variation (input effects the response). The Full Factorial Design of Experiment Method is used to assess the results of the hardness test in accordance with the testing hypothesis. Design of Experiment (DOE) has been widely used to determine design factors that significantly influence target responses and build empirical models that represent relationships between significant factors. Reviewing the literature revealed that the majority of researchers explored various DOE. Response Tempering heat treatment with Quenching Oil media, this study used AISI 4140 material with a diameter of 29 mm, 33 mm and 35 mm. Results AISI 4140 of commercial production by partial cutting are then taken for hardness testing. The Full Factorial Design of Experiment Method is used to assess the results of the hardness test in accordance with the hypothesis according to the analysis of variance(Anova). The response of the hardness test data input in the 300 & 900 direction is not influenced by the AISI 4140 material dimensions and the direction of the test surface data retrieval. Fo, 5%, 2.15 = 3.68, then Fo = 50.11> 3.68 in the 300 test direction and Fo, 5%, 2.15 = 3.68, then Fo = 70.79> 3, 68, in the 900 test direction where H0 cannot be accepted while H1 is accepted.

Abstract

Electric car consists of a chassis that carries the vehicle's load, such as an electric motor to drive the wheels, and a battery as an energy source for the electric motor. Overall vehicle performance is controlled and monitored by the battery and engine controller systems. The objectives of the research on Design and Analysis of Electric Car Chassis Using the Finite Element Method Using Solidworks 2017 can be described as follows: Identifying aspects of the design strength of the AISI 4130 frame (hollow steel 40 x 60 mm). The design determines the wheel alignment of the wheel geometry, the angle of inclination of this wheel will later be used as a reference when making the frame and continues to make the geometry for the wheels and the width of the rear wheel tread. This axle uses a vehicle equivalent axle. Measurement, the rear wheel track of the vehicle axle is 1126 mm, and the front wheel track uses a track with a different width. For easier handling during maneuvers, the wheelbase is fixed at 1835.5mm, so the front front wheel track is wider than the rear wheel track. Mesh on the chassis using tetrahedral as shown in figure 2.a then loading is given to the node point position where the driver is on the chassis supporting the driver's load is 750 N and the battery is added, the weight of the BLDC motor and solar panel is 310 N and the maneuver is 100 N. The simulation results show the voltage value VonMises Stress with AISI 4130 material with a maximum stress value of 2.796 x 108 Pa, right maneuver 3.92 x 108 Pa and left maneuver 4.071 x 108 Pa with a given load of 1060 N. The maximum vonmises stress occurs when the kart maneuvers left while the highest maximum displacement occurs only due to the influence of gravity without being affected by vehicle maneuvers so that maneuvers can reduce displacement.

Abstract

The nature of electrode with the base metal is as important as the welding speed and design of joint. One of the metal joining systems is the SMAW (shielded Metal Arc Welding) welding system with wrapped electrodes. Generally, for welding high strength steels a higher heat input is used in the SMAW process compared to other processes. The influence of heat input and welding speed affects the characteristics of the material, microstructural properties and mechanical properties of the weld. The type of electrode used is current according to the material to be welded, in this case the author uses AWS E-7016 welding wire with D32 mm and AISI 1016 material with a thickness of 12 mm using V connection. The welding process occurs because of the resistance of an electric current flowing between the electrode and the welding material which causes heat to reach 30000C, thus making the electrode and the material to be welded melt. Welding currents of 100 A and 120 A have tensile strength, ultimate strength and elongation above 20% which is the result of the same good strength as the parent metal.The purpose of this study was to obtain the tensile strength and bending strength of the welded joint with V seam welding and to compare the results of the tensile strength and bending strength with the effect of high current variations on the electrode during welding.The results of the buckling test for a current of 80 a showed a fracture in the WM/HAZ, fracture occurred in the welding area, while for a current of 100 A, fine cracks were obtained in the WM/HAZ in the weld area and a current of 120 A obtained a Void: 0.8 with better welding results.

Abstract

Plyllostachys bamboosoides known in Asia, also called bamboo fence, is one of the choices for the construction and manufacture of furniture. Its properties also make it useful in a number of arts and crafts. The influence of ductility and toughness factors is at the microcellular level; which includes the pattern of arrangement, morphology, and mechanical properties of bamboo cells. The perfect combination of fibers and compressible parenchyma cells is the key to the excellent flexible deformation of bamboo, originally illustrated the elongation of parenchyma cells under bending through low resolution electron micrographs. The angle of the microfibrils in the cell wall plays an important role in the mechanical properties of the wood and the occurrence of interface delamination followed by matrix failure and fiber breakdown under natural growth. Tensile strength and strain due to the influence of variations in thickness and volume of composite composition with variations in manufacturing methods that can affect its mechanical properties so that it is expected to determine a good composition. The addition of bamboo fiber as a filler of Polyester resin has a significant effect on the tensile strength. Tensile testing with an angle of 450 with a thickness 1 mm resulted in the highest ultimate stress 0.027 M.Pa with 25%:75% polyester resin of bamboo fiber. The tensile strength is increased by increasing the volume of the bamboo fiber and reducing the thickness of the bamboo fiber increases the tensile strength of the composite.
