Department of Mechanical Engineering, Diponegoro University, Semarang, Indonesia Abstract - Welded brake pedal component connection

using GMAW process with CO2 protective gas 100%

contains spatter weld defects, weld-bead ripple, undercut and porosity at the level limit of 8.2%. By replacing 100%

CO2protective gas with Ar 75% CO2 protective blend gas 25%, welding defects are reduced to a level limit of 0.88%

dominated by spatters while other welding defects are virtually non-existless. Defective welding spatter with protective gas CO2100% shows a level of 2.77%. By using Ar 75% CO2 protective mixed gas 25%, defective welding spatters decreased to the level of 1.11%. Therefore, the replacement of protective gases in the GMAW process led to a 150% improvement in the quality of brake pedal welding joints. This will have an impact on improving the competitiveness of the industrial brake pedal components of two-wheeled motor vehicles.

Keywords: brake pedal, spatter, GMAW welding process, CO2 protective gas, Ar 75% CO2 protective mix gas 25%.

I. INTRODUCTION

The development of national industries that are part of the industrialization process becomes a challenge for the industrial sector to compete closely, especially in the era of globalization. The development towards free trade will have an increasing impact on opportunities as well as threats to small and medium-sized industries in the country at the production level with guarantees of the quality of products to be marketed to be defended. In small industries the advantages and disadvantages vary greatly due to lack of knowledge of production technology, quality control and human resources improvement. The Small and Medium Industry of West Java is able to produce transportation equipment components to support the development of the auto industry- two-wheeled motor vehicle motifs, especially brake pedal products, but some of its products are still rejected because they do not meet customer specifications.

From the observation of visual test results of salt spray products brake pedal products at Bandung Technical Materials and Goods Hall found rusty products on their welding joints at exposures of 48 to 96 hours at rust levels of 1 to 20% [2].

Welding defects in the form of ripple weld-bead, spatter, porosity and undercut on the surface of the welding joint of the brake pedal components when the coating process is implemented the result is not perfect so it is easy to rust [3].

Therefore, this welding defect must be prevented so that the coating process can be directly good and the result is flat on the surface of the parent material as well as the welding joint.

A spatter (S) is a high-temperature metal filler jump from the electrode's flame arc to the surface of the welding joint and its surroundings. Called a defect because it can interfere with the coating process, the spatter should be cleaned. This defect grows when high current and stickout filler wire are high so that the radiating liquid wire filler breaks in the air touching the welding crater and a portion of the beam bouncing into the air usually occurs in the transfer mode spray[4]. Metal spatter wasted is a loss of weight loss wire filler.

Porosity (P) surfaces are holes individually or in groups growing on the surface of welding joints, these defects can be caused by moist, dirty, oil or grease parent material. The flow of protective gas from the nozzle torch as a protection area of liquid welding metal is not functioning properly, such as unstable gas flow, turbulence, less gas flow pressure, or clogged torch nozzle is the main cause of porosity failure.

Ripple weld-bead (RWB) welding joint surface is uneven;

this defect can be grown by unstable torch movement or high welding speed giving rise to rough welding surfaces.

Undercut (UC) is a takikan between the parent material and welding metal is generally on the sides of the weld. This defect can be grown by high heat input and welding speed, the melting main material is not filled by a melting filler[4]. The undercut on the surface of the takikan-shaped welding joint will thicken the chrome & nickel layer unevenly the impact is easily corrosion so that the quality of the coating becomes low [3,4].

The use of CO2 protectivegas100% as a reactive gas commonly used to weld carbon steel is not as good as inert gas tends to grow spatter, deep penetration, thick welding smoke, low deposit efficiency, uneven welding connection surface,

Abstract - A tetrahedron is a pyramid with four sides that are equilateral triangles. It is one of the basic building blocks of an object. So it is widely used in engineering.

Determining the volume of tetrahedra is very important. It helps us to determine the exact mass of an object. This is very important work in engineering design. In addition to the tetrahedral volume formulas, this article gives some more tetrahedral volume formulas and some applications of its in engineering.

Keywords: Tetrahedron, Tet Traingle, Trai Equation, Eqt.

I. INTRODUCTION

The attractiveness of technology to simple structures shown in the aestheticization process is increasing. Simple geometries are considered to be the best response to mass production modes. The study and application of polyhedra to create architectural spatial forms is an inevitable trend. And the trend in the design of modern architectural works is how to create large space beyond the span, simple but iconic architectural shapes. Therefore, the application of equal and semi-uniform polyhedra into the design and construction of architectural works in the world is very necessary and deserves attention. Not confined to lines, meeting the architectural creativity of the design engineers, being able to structure complex shapes without columns is one of the many advantages of the space roof trusses appears more and more in the diverse architectural complex in the world today.

Universidad Autónoma de Ciudad Juárez. Ave. Del Charro 450 N Cd. Juárez, Chih. CP 32310, México Abstract - The capacity of a wing to generate lift force is

determined by the lift and drag coefficients produced by the effects of the airflow path along the selected airfoil and surface geometry. On this research, a methodology has been developed, based on the System Life Cycle management tool and mathematical models to perform a theoretical, computational, and experimental aerodynamic analysis in order to design and model a fixed wing for an UAV.

Keywords: Aerodynamic analysis, design and model, fixed wing, Unmanned Aerial Vehicle.

I. INTRODUCTION

Designing a wing layout is an engineering process that integrates objectives, synthesis, analysis, test, evaluation, construction, and operation as fundamental elements that are continuously iterated until the accomplishment of design requirements. A management tool that “[…] includes design, development, production, operation, support, and disposal”

[1], is the System Life Cycle. The application of this procedure into the methodology developed on this research, divided the wing design into two major phases, acquisition and utilization.

Figure 1: The system life cycle [1]

As it is illustrated on Fig. 1, in the acquisition phase, the conceptual design, preliminary design, and detailed design were performed and evaluated before constructing the fixed wing prototype.

As a basis to set the aerodynamic limitations and design purposes were taken requirements listed below:

 Design a fixed wing capable of generating a force of 245.166 N to lift the maximum gross weight of the UAV.

 Design a fixed wing capable to generate lift required with a minimum speed of 12 m/s.

In the preliminary design, the mathematical models from Sadraey and Raymer were implemented to analyze and define the optimum wing configuration, concluding that it consists on a high double taper wing using an airfoil E423. Also, a wing surface of 1.7778 𝑚² was calculated with a wing loading of 137.9 _𝑚^𝑁₂ . After the theoretical analysis, a wind tunnel test was carried out to ensure that the preliminary wing layout met the objectives previously established.

During the detailed design, methods from Sadraey, Abbot, and Anderson were executed to analyze the lift distribution and performance curves to determine the optimal angle of incidence for cruise flight. Results were corroborated and evaluated with Computational Fluid Dynamics (CFD).

To end with the acquisition phase, the wing prototype was constructed using 20 ribs and 2 main spars. Each rib was located according to each section analyzed on the lift distribution curve. Finally, the prototype was used on a UAV of 22 kilograms of gross weight and propelled by a Scorpion SII-4020 electrical motor, having a successful flight circuit.

The methodology presented on this paper pretends to provide the basis to analyze and design fixed wings for UAVs with similar cargo applications. The method is briefly described in this paper throughout the Section II according with each phase of the System Life Cycle.

II.METHODS, ANALYSIS AND TESTS

In this work, the System Life Cycle was adapted for designing a wing as it is shown on Fig. 2. CDR, PDR and FDR refer to the revisions after each design stage. [1]
