Abstract

Sling bearings are one of the important components in the cable car transportation system. These bearings function to support the weight of the cable car and reduce friction between the train and the rail/sling so that the train can move smoothly and safely. To produce quality sling bearings, a precise and accurate machining process is required. The manufacturing process of ropeway sling bearings goes through a machining process, where raw materials that are usually metals or metal alloys will be cut, shaped, and polished to form the desired bearing shape. Fixture machining is one of the most commonly used techniques in the machining process, where the workpiece is clamped or fastened to a specially designed fixture so that the workpiece remains stable during the machining process. The purpose of this engineering is to produce a fixture design for sling bearing components with increased quantity and quality of products on CNC machines by validating the design through simulation. In this study, tests were conducted using a conventional machining fixture and a machining fixture equipped with a pneumatic system. The test results show that the machining fixture equipped with a pneumatic system is able to increase the production speed and efficiency of cable car sling bearings by up to 20% compared to the conventional fixture. This research makes an important contribution to the cable car sling bearing manufacturing industry in improving production efficiency and final product quality. In addition, this research can also be a reference for further research on the optimization of the cable car sling bearing production process.

Abstract

Pertumbuhan industri kendaraan listrik di Indonesia menuntut kesiapan sumber daya manusia dalam pengoperasian dan perawatan mesin. Untuk mendukung hal tersebut, tim dosen Jurusan Teknik Mesin Politeknik Negeri Jakarta melaksanakan program Pengabdian Kepada Masyarakat dengan judul Pembuatan Modul Ajar dan Pelatihan Basic Machine Operation Technique (BMOT) bagi CV Rezeki Sejahtera Bersama dan mitra bengkel sepeda motor di wilayah Depok dan sekitarnya. Kegiatan ini mengombinasikan pembelajaran teori dan praktik, mencakup pengoperasian mesin dasar, pengelasan, prosedur keselamatan kerja (K3), serta pengenalan alat kerja yang relevan dengan dunia usaha kendaraan listrik. Sebanyak 25 peserta mengikuti pelatihan yang dievaluasi melalui pre-test dan post-test. Hasil menunjukkan peningkatan kompetensi sebesar 78%. Program ini menjadi langkah strategis dalam menyiapkan tenaga kerja bengkel lokal menghadapi transisi menuju industri kendaraan listrik.

Abstract

Dynamometer testing (dynotest) is essential for evaluating electric vehicle (EV) performance under controlled laboratory conditions, enabling repeatable measurement of power, torque, efficiency, and energy consumption while emulating real-world driving cycles. This review surveys recent developments in EV dynotesting, highlighting IEEE and international test standards, key performance parameters, and evolving methodologies. We compare chassis and hub dyno architectures, including new “vehicle-in-the-loop” and modular test benches, and discuss integration of hardware-in-the-loop (HIL) simulation for real-time controller validation. Standardized drive cycles (e.g. WLTP, EPA/UDDS, JC08) are widely used on dynos to benchmark EV energy use. We summarize representative studies that apply dynotests to EV powertrains, including single-motor and dual-/multi-motor drivetrains. Emerging challenges are reviewed: bidirectional (regen) energy flow, thermal management under high load, synchronization of multiple drive units and batteries, and specialized needs for all-wheel-drive (AWD) and multi-motor EV testing. The review concludes that comprehensive dynotest methods, combined with rigorous standards, HIL integration, and advanced data analysis, are critical for validating next-generation EV drivetrains and enabling accurate energy-consumption benchmarking. Future work should address remaining gaps in multi-axis dyno platforms, long-term durability tests, and AI-driven real-time analysis during dyno runs.
