Uji Berat pada kereta atau gerbong dilakukan dengan cara menghitung total berat Kereta dan menghitung distribusi berat pada masing-masing roda dengan cara menimbang beban yang diterima pada setiap roda [1-3]. Tujuan dari penelitian ini adalah membuat konsep desain dan simulasi alat uji berat kereta portabel yang dapat di gunakan untuk mengukur berat kereta di sepanjang jalan rel secara real time dan akurat. Tujuan pengukuran berat kereta adalah untuk memastikan berat kereta terdistribusi secara merata pada tiap roda kereta dan memastikan agar muatan kereta tidak overload disesuaikan dengan kemampuan jalan rel. Yang menjadi input faktor dalam penelitian ini adalah load atau beban, type meshing, material dan model dari load cell dan dudukan load cell. Proses penelitian yang di lakukan berupa desain dan simulasi dari bentuk load cell dan bentuk dudukan load cell. Output faktor dari penelitian ini adalah kekuatan struktur dari load cell dan kekuatan struktur dari dudukan load cell. Nilai tegangan ijin untuk baja ASTM A36 sebesar 160 MPa. Nilai tegangan ijin untuk baja SM 490 sebesar 230, dan nilai tegangan ijin untuk baja ASSAB 718 sebesar 574.

Abstract: A residential dump transport to a temporary garbage disposal medium using a human-powered dump cart is not humane. An electrical-powered propulsion system can be one of the eco-friendly system which can be implemented to the cart, thus substitutes the human’s role to do so. This propulsion is analyzed by using vehicle dynamic analysis. Vehicle dynamic analysis which is conducted, discuss tractive effort which overcomes resistances during vehicle’s movement and accelerates the vehicle, and specification of drive train, used to drive it. Based on analytical result, it is obtained an electric dump cart model which can move at a 25 km/h maximum velocity, 20° maximum inclination while it is empty loaded, and 10° maximum inclination while it is fully loaded.

Abstract: Pollution levels over time has been increased. One of the causes of the pollution are Internal combustion engine vehicle. In Indonesia, the air pollution produced by motor vehicles approximately 55 micrograms per cubic meter CO2. One of the solution to overcome the pollution problem is to create environmentally friendly vehicles using electric motor. In this paper will discuss about the design of a concept of environmentally friendly personal vehicle, which is used 3 wheel and can carry a single passenger. The process is design using the CAD software in three dimensional design, then static analysis was conducted using FEA to produce the maximum stress and the critical location due to the load from the design of the vehicle.

The study comprises dynotest design and analysis to measure torque and horsepower. Basically, a dynotest carried out by apply certain load to the axle of a combustion motor through the braking mechanism of its crankshaft. Due to the high price of a Dynotest unit in the market, it is relatively difficult for a developing institution to own it on their site. The study target to design a simple and good accurate Dynotest within a reasonable price. The study used a common standard method for design analysis which rely on function and structural approach. Functionally, Dynotest is designed to be used to an ouput of an electical motor. Loading on motor shaft was done by disc brake braking mechanism. Structurally, Dynotest was designed to use rollers. As a main component, its mounting construction is connected to a motor to generate electrical power. Power transmitted from the motor to Dynotest through a center joint shaft, torque measured by load cell while the rotation of shaft itself counted by a digital tachometer. Test result show that electricity was produced from the simple construction and Dynotest functioned well in measuring it. Measurement data of roller support shaft performance showed a motor torque performance curve which are similar with the typical of similar Dynotest. Construction Test done by applying Solid Work software analysis to some components partially on rollers and on the construction assembly as a whole unit

Lightweight frame design plays a critical role in improving the efficiency and sustainability of electric buses. This study aims to explore the optimization of electric bus frame design through the application of Value Engineering (VE), using a systematic literature review (SLR) supported by technical simulation references. The review focused on key parameters, including material selection, structural topology, component dimensions, and production costs, analyzed across more than 40 publications from reputable databases over the past decade. Various studies demonstrate that substituting conventional steel with aluminum alloy 6063 can reduce frame weight by up to 30%, while topology optimization based on Finite Element Analysis (FEA) achieves more efficient load distribution and structural integrity. Additionally, shifting from manual to robotic welding methods has shown to enhance production efficiency by approximately 20%. Despite higher initial costs, VE supports long-term benefits by reducing operational costs, improving energy consumption, and aligning with sustainability goals. The findings suggest that integrating VE into the early stages of electric bus frame design offers a strategic pathway toward lighter, safer, and more cost-effective transportation solutions.

Landing Gear Drop Test (LGDT) utilizes the apparatus requiring a substantial time and cost. Virtual LGDT (vLGDT) using MSC ADAMS software is one of the solutions for initial stage to testing landing gear. From simulation with vsink 1.7 m/s and load 22000 N obtained contact/impact force that ensue in MSC ADAMS was 73650 N, while from experimental was 73612 N. The difference between vLGDT and LGDT result is 0.05 %. To obtain ground reaction load factor below 3 in vsink = 3.05 m/s, the rubber damper should have stiffness in the range of 1900 - 2100 N/mm and for the tire pressure of 60 - 65 psi.
