Abstract
Rumah kopling motor matic merupakan komponen penting dalam sistem CVT yang meneruskan tenaga mesin ke roda belakang, namun desain konvensionalnya masih relatif berat sehingga memengaruhi efisiensi bahan bakar dan akselerasi. Penelitian ini merancang ulang rumah kopling dengan optimasi topologi berbasis struktur lattice untuk mengurangi massa sekaligus menjaga kekuatan mekanis. Simulasi dilakukan menggunakan Finite Element Analysis (FEA) dengan Ansys Workbench dan Autodesk Inventor, membandingkan beberapa variasi desain lattice dengan model standar. Analisis meliputi deformasi, tegangan maksimum, regangan, faktor keamanan, serta efisiensi berat. Hasil menunjukkan bahwa struktur lattice mampu menurunkan massa secara signifikan, menghasilkan distribusi tegangan lebih merata, deformasi lebih kecil, dan faktor keamanan tetap aman. Kesimpulannya, desain berbasis lattice efektif dalam reduksi berat sekaligus meningkatkan performa mekanis, serta berkontribusi pada pengembangan teknologi manufaktur aditif yang memungkinkan realisasi geometri kompleks dengan presisi tinggi, mendukung efisiensi kendaraan dan tren desain ringan berkelanjutan di industri otomotif. ***** The clutch housing of automatic motorcycles (motor matic) is a key component in the Continuously Variable Transmission (CVT) system, transmitting engine power to the rear wheel, yet conventional designs remain relatively heavy and reduce fuel efficiency and acceleration. This study redesigns the clutch housing using topology optimization with lattice structures to reduce mass while maintaining strength. Finite Element Analysis (FEA) simulations with Ansys Workbench and Autodesk Inventor compared several lattice-based models against the standard design, analyzing deformation, maximum stress, strain, safety factor, and weight efficiency. Results show that lattice structures significantly lower mass, produce smaller deformation, distribute stress more evenly, and maintain safety factors above required limits. Overall, lattice-based optimization proves effective for lightweight yet durable clutch housings, contributing to additive manufacturing advancements such as Selective Laser Melting (SLM) and supporting efficient, sustainable design trends in the automotive industry.
