Abstract

The hydraulic transmission system is a key component of an excavator because it transfers fluid power from the pump to the actuators to produce working movements of the boom, arm, and bucket. This study aims to analyze the performance of the hydraulic transmission system in a crawler-type miniature excavator prototype based on working load, cylinder cross-sectional area, working pressure, cylinder speed, flow rate, and pump requirement. The research used a Research and Development (R&D) method with limited stages of define, design, development, and disseminate. The prototype was designed using CAD software, manufactured through 3D printing with PLA+ material, and equipped with a simple hydraulic system to operate the boom, arm, and bucket cylinders. The analysis was conducted by determining load distribution based on the center of gravity, calculating the force acting on each cylinder, and determining the cylinder area, working pressure, and actuator flow rate. The results showed that the boom cylinder received the highest load of 20 kg, while the arm and bucket cylinders received 10 kg and 5 kg, respectively. The boom cylinder area was 0.000314 m², while the arm and bucket cylinder areas were 0.000491 m². The required working pressures for the boom, arm, and bucket cylinders were 72 bar, 30 bar, and 20 bar, with flow rates of 0.565 lpm, 1.470 lpm, and 2.063 lpm, respectively. These results indicate that the boom cylinder is the most critical component based on pressure requirement, while the bucket cylinder determines the highest flow demand. Therefore, pump selection should consider a maximum pressure of 72 bar and a minimum flow rate of 2.063 lpm, with additional flow capacity when multiple actuators operate simultaneously.

Abstract

This research aims to analyze the performance of the electric drive system in electric shuttle busses converted from internal combustion engine (ICE) vehicles to battery-based electric vehicles. The focus of the study is directed toward evaluating the technical characteristics of the electric motor, battery capacity and endurance, range estimation, power requirements, and the efficiency of the vehicle's drive system. The research method used is a quantitative descriptive method, literature study, and mathematical modeling based on the vehicle's technical specifications, including vehicle mass, battery capacity, power and torque of the electric motor, as well as vehicle resistance parameters such as rolling resistance and aerodynamic drag. The analysis results show that 2 lithium iron phosphate (LiFePO₄) batteries with a capacity of 15.84 kWh can support an operating time of approximately 6.46 hours with an estimated range of 323 km at a speed of 50 km/h. The motor power calculation shows that the electric motor has a maximum power of 96.33 kW, while the actual power requirement of the vehicle on flat roads is only about 4.8 kW. These results indicate that the electric drive system has sufficient power reserves and is technically feasible for use in the converted electric shuttle bus

Abstract

The lifting system is a major component of a rough terrain crane that functions to lift and move loads therefore, it requires a structure capable of safely withstanding applied loads. This study aimed to analyze Von Mises stress, displacement, and safety factor, as well as to determine the lifting capacity limit of a rough terrain crane simulator lifting system made of Acrylonitrile Butadiene Styrene (ABS). The research employed the Finite Element Analysis (FEA) method using Autodesk Fusion 360 with load variations of 4.90 N, 9.81 N, and 19.61 N. The simulation results showed that increasing loads caused the maximum Von Mises stress to increase from 44.348 MPa to 177.484 MPa and the maximum displacement to increase from 36.489 mm to 146.030 mm. The minimum safety factor decreased from 0.451 to 0.113. The highest stress concentration for all loading variations occurred at the base joint area of the lifting system. The results indicated that the ABS structure did not meet the safety criteria because all loading variations produced safety factor values below 1 and working stresses exceeding the material yield strength of 20 MPa. Structural geometry optimization or the use of higher-strength materials is required to improve the lifting system’s capacity and safety.

Abstract

Shuttle bus listrik memerlukan penyaluran daya yang efisien dari baterai menuju motor penggerak, terutama pada bagian controller yang melakukan pengaturan aliran daya dan proses switching. Penelitian ini bertujuan menganalisis rugi daya input-output controller motor BLDC 10 kW pada Electric Shuttle Bus 14 Seats menggunakan Power analyzer PW6001. Penelitian menggunakan metode eksperimen kuantitatif dengan tiga kondisi pembebanan, yaitu beban kosong, beban setengah, dan beban penuh, serta tiga tingkat kecepatan konstan, yaitu 10, 20, dan 30 km/jam. Setiap skenario pengujian dilakukan sebanyak tiga kali sehingga diperoleh 27 data utama. Parameter yang dianalisis meliputi daya input controller (Pin), daya output controller (Pout), rugi daya (Ploss), dan efisiensi controller. Hasil penelitian menunjukkan bahwa rugi daya meningkat secara konsisten seiring kenaikan kecepatan operasi. Rugi daya rata-rata terendah terjadi pada kondisi beban setengah dengan kecepatan 10 km/jam sebesar 775,4 W, sedangkan rugi daya rata-rata tertinggi terjadi pada kondisi beban penuh dengan kecepatan 30 km/jam sebesar 1948,8 W. Efisiensi controller lebih rendah pada kecepatan 10 km/jam dan meningkat pada kecepatan 20-30 km/jam. Temuan ini menunjukkan bahwa kecepatan operasi memiliki pengaruh yang lebih konsisten terhadap rugi daya controller dibandingkan pembebanan.   Kata kunci: daya input-output, efisiensi controller, motor BLDC, PW6001, rugi daya

Abstract

A miniature hydraulic forklift is a tool that can be used as a learning medium, simulation, or prototype for a goods lifting system. Structural strength is an important aspect that determines the safety level of a miniature hydraulic forklift during loading. This study aims to analyze the structural strength of a miniature hydraulic forklift using the Finite Element Analysis (FEA) method based on Von Mises stress, displacement, and safety factor parameters. The study was conducted by creating a three-dimensional model of a miniature hydraulic forklift using Autodesk Fusion 360, then conducting static simulations with loading variations of 9.81 N, 19.6 N, and 29.4 N. The simulation results show that a 9.81 N load produces a maximum Von Mises stress of 19.154 MPa, a maximum displacement of 24.780 mm, and a safety factor of 1.044. A 19.6 N load produces a maximum Von Mises stress of 38.308 MPa, a maximum displacement of 49.561 mm, and a safety factor of 0.522. The 29.4 N load produces a maximum Von Mises stress of 57.461 MPa, a maximum displacement of 74.341 mm, and a safety factor of 0.348. The highest stress distribution occurs in the connection area between the fork and the fork seat which is a critical part of the structure. The results of the study indicate that increasing the load causes an increase in the Von Mises stress and displacement values ​​and a decrease in the safety factor value. The miniature hydraulic forklift structure is still safe to use at a load of 9.81 N because it has a safety factor value greater than one, while loads of 19.6 N and 29.4 N indicate unsafe conditions. The results of this study can be the basis for developing a miniature hydraulic forklift design that has a better lifting capacity and safety level.
