Abstract

Solar panel-based electric charging stations are a combination of electricity sources and solar panels, allowing efficient and effective charging and helping to source electricity from natural energy in the form of renewable energy, namely the sun. The use of solar panels as the main energy source can reduce dependence on limited energy sources and produce lower greenhouse gas emissions and reduce dependence on fossil energy sources. The purpose of this thesis is to design and analyze the strength and durability of solar panel-based electric charging stations on their supports. The method used in this study is quantitative data taken using Ansys software simulations. The results showed that Design 1 on the solar panel supports had a maximum deformation of 0.2397 mm at an angle of 70 and design 2 produced a maximum deformation of 0.0052439 mm at an angle of 70 to the right/left. Based on these results, it can be concluded that the design of 1 solar panel support is better in terms of strength and durability because the load on the solar panel that is on the support only has an effect of 0.2397 mm which can withstand a load of around 320 N.

Abstract

The use of solar panels in electric power charging stations is becoming increasingly popular as part of efforts to adopt renewable energy sources. In this context, the structural framework supporting the solar panels plays a crucial role in maintaining the stability and reliability of the system. Therefore, this thesis aims to investigate the influence of various structural framework variations on the strength of static loading in solar-powered electric charging stations. The research methodology employed simulation of static loading at three different load levels, namely 40 kg, 50 kg, and 60 kg. The analysis was conducted by comparing the equivalent stresses and total deformations between "Design 1" and "Design 2" at each load level. The research findings reveal significant differences in equivalent stresses and total deformations between the two designs at each load level. Design 1, with a stiffer structural framework, exhibited higher equivalent stresses and greater total deformations compared to Design 2. Consequently, this study provides a deeper understanding of the influence of various structural framework variations on the strength of static loading in solar panel support structures. These findings can serve as a basis for optimizing the structural design of solar-powered electric charging systems.

Abstract

High wind velocity can induce external pressures and loads on the structural framework of an Electric Vehicle Charging Station (EVCS), jeopardizing the overall stability and structural integrity of the framework. The objective of this research is to ascertain the magnitude of aerodynamic drag force and the maximum pressure values on the surface of the EVCS framework, with respect to variations in wind velocity. The methodology employed in this study involves Computational Fluid Dynamics (CFD) simulations utilizing the Solidworks Flow Simulation. Three wind velocity scenarios were considered: 3 km/h, 6 km/h, and 9 km/h, allowing for the observation of airflow acceleration phenomena, aerodynamic drag force values, and peak pressure distributions on the EVCS framework's surface. Research findings reveal that the aerodynamic drag force at a wind velocity of 3 km/h measures 22,34 N, escalating to 90,42 N at 6 km/h wind velocity, and reaching 202,7 N at 9 km/h wind velocity. Furthermore, the highest-pressure value at a wind velocity of 3 km/h is 101325,45 Pa. As the wind velocity increases to 6 km/h, the maximum pressure value rises to 101338,18 Pa. Under the condition of the highest input wind velocity, i.e., 9 km/h, the peak pressure reaches 101353,46 Pa.

Abstract

The manufacturing process is still being developed. The injection molding process is a manufacturing process that is often used in the production of plastic products. Using software with predetermined parameters, injection mold simulation of a predetermined product is carried out on the carabiner design. The parameters used are then assessed with quality prediction based on the best simulation results. If there is a product that does not meet the quality prediction value given (i.e. the value is less than optimal), improvements are made by changing the injection mold design or mold design. Three runner layout designs were made in such a way as to assess which of the runner layout designs for the carabiner mold had the highest quality prediction value. Then, from each runner layout design, variations in gate diameter sizes of 2 mm, 4 mm and 6 mm were made. Based on the simulation results that have been carried out, the best runner and gate layout is obtained in Design 1 with a gate diameter of 4 mm, whose quality prediction value reaches 100%. Then, the lowest quality prediction was obtained in Design 1 with a gate diameter of 6 mm.

Abstract

The eddy current dynamometer is a torque test measuring instrument calculated from the loading of an engine that rotates on its shaft to stop a rate from engine rotation and produce the engine loading power. The eddy current dynamometer is a torque test measuring instrument calculated from the loading of an engine that rotates on its shaft to stop a rate from engine rotation and produce the engine loading power. The braking system is one of the most important things in an engine, to stop the engine from moving braking is needed. This study aims to calculate the torque of the eddy current dynamometer. With a copper wire diameter of 0.85 mm and 560 windings of the core coil. Torque results show an increase in each variation in current and rotation. The torque power reaches its maximum point at 3000 RPM revolutions at 15V voltage at 25.4A amperes, namely 2.15 Nm. The number of windings on the wire coil is proportional to the magnitude of the solenoid value. The calculation of the maximum value induction at the center of the magnetic force pole core is obtained from the wire diameter of 0.85mm and 560 windings of the core coil at a voltage of 15V in amperes of 25.4A at a roller rotation of 3000 RPM of 254-4 Tesla or Wb/m2. And from both ends of the polar core solenoids, the result of magnetic strength is smaller than the magnetic induction center of the polar core, which is 127-4 Tesla or Wb/m2.

Abstract

Testing the torque of a motorized vehicle, especially two-wheeled motorized vehicles (motorcycles), often requires equipment that is considered expensive and difficult to access on a small laboratory scale. However, the torque test is considered important to find out how a motorbike works using certain fuels, for example widely used fuel mixtures such as gasoline mixed with certain vegetable oils, to find alternative fuels. Therefore, a simple torque test tool is needed that can be designed and used as a preliminary study of alternative fuels. In this study, designed a simple eddy current-based torque test frame with a roller conveyor. Before the frame is formed, the frame design is outlined using the student version of ANSYS software to study the loading characteristics and promises. The simulation results show that the frame design can be used with a loading force of 294 N in the eddy current area and 981 N in the roller area. The frame was then manufactured using hollow iron measuring 4x6 cm with ASTM A500 material type. This research has succeeded in designing and producing a simple eddy current-based torque test frame using a roller conveyor.
