Abstract

Optimalisasi desain Upright depan mobil formula Sapuangin Speed dengan optimasi topologi. Optimasi topologi merupakan pengurangan massa tanpa mengurangi kekuatan strukturnya, sehingga didapatkan desain yang optimal sesuai dengan gaya yang bekerja pada Upright. Oleh karena itu, perlu dilakukan penelitian untuk mengetahui tegangan dan deformasi yang terjadi pada desain Upright depan Sapuangin Speed sebelum optimasi, dan untuk mengetahui tegangan, deformasi, dan faktor keamanan pada desain Upright depan Sapuangin Speed. Setelah optimasi topologi dengan beberapa mass retain dan mengetahui desain mana yang memiliki kualitas terbaik dan dapat diproduksi pada mesin CNC Milling 3-axis. Penelitian ini terdiri dari analisis beban pada Upright depan pada saat deselerasi, akselerasi, dan cornering, yang memberikan beban pada bearing Upright depan, mounting kaliper rem, dan mounting control arm. Desain Upright depan disimulasikan menggunakan simulasi static structural dengan menggunakan software elemen hingga, kemudian simulasi optimasi topologi Upright depan menggunakan mass retain 60%, 50%, dan 40%. Selanjutnya Upright dengan ketiga mass retain tersebut disimulasi static structural. Pada penelitian ini dihasilkan desain Upright dengan masss retain 40% material Al 7075 T6. Upright mempunyai berat 459 g, dan didapatkan hasil simulasi static mempunyai deformasi sebesar 0,020529 dan -0,022078 mm searah sumbu X pada pembebanan deselerasi.

Topology optimization is a method for reducing mass without compromising structural strength, resulting in an optimal design tailored to the loads acting on the Upright. This study aims to evaluate the stress and deformation of the front Upright design of Sapuangin Speed before optimization and analyze the stress, deformation, and safety factor after topology optimization. Various mass retain percentages are considered to identify the best design that can be manufactured using a 3-axis CNC milling machine. The research includes load analysis on the front Upright during deceleration, acceleration, and cornering, which subjects the Upright bearing, brake caliper mounting, and control arm mounting to significant loads. The front Upright design is simulated using static structural analysis with finite element software. Topology optimization simulations are then conducted with mass retain percentages of 60%, 50%, and 40%. Static structural simulations are performed for each optimized design. The results indicate that the Upright design with a 40% mass retain using Al 7075 T6 material weighs 459 g. The static simulation reveals deformations of 0.020529 mm and -0.022078 mm along the X-axis under deceleration loading.
