Abstract

Upright merupakan bagian dari sistem suspensi mobil yang berperan penting dalam stabilitas dan kenyamanan mobil. Untuk menunjang ke stabilitasan berkendara komponen upright harus didesain ringan tapi kuat dalam menahan pembebanan ketika mobil dalam kondisi akselerasi, deselerasi dan cornering. Untuk mewujudkan suatu komponen yang kuat, maka komponen harus mampu menerima gaya gaya pembebanan yang bekerja pada komponen tersebut. Dari gaya gaya yang bekerja pada komponen tersebut menghasilkan tegangan dan deformasi. Dimana benda kerja dikatakan aman apabila besar tegangan yang bekerja lebih kecil dari yiled strength dari material komponen. Tidak hanya kuat yang menjadi patokan tapi komponen juga harus ringan maka diperlukan adanya suatu metode yaitu metode optimasi topology. Dengan menggunakan software finite element membuat proses optimasi menjadi sangat mudah dan sangat cepat dan akurasi maksimal. Prosesnya yaitu dengan input model dari software CAD, mendefinisikan material, input constraint dan vector gaya, proses meshing, dan yang terakhir proses solution. Dari hasil simulasi tersebut akan diketahui nilai dari solution berupa besar tegangan, deformasi dan safety factor dari komponen upright. Dari beberapa desain optimasi topology nantinya akan dibandingkan untuk mengetahui mana desain yang terbaik yang nantinya akan dijadikan rekomendasi desain. ==================================================================================================== Upright is part of the car's suspension system that plays an important role in creating and comforting the car. To support driving safety, upright components must be designed to be light but strong to withstand loading when the car is in conditions of acceleration, deceleration and cornering. To realize a strong component, the component must be able to accept the loading force acting on the component. From the forces acting on these components produce stresses and deformations. Where the workpiece is said to be safe if the working stress is smaller than the yield strength of the component material. Not only strong as a benchmark, but components must also be lightweight, so we need a method, namely a topology optimization method. Using finite element software makes the optimization process very easy and very fast with maximum accuracy. The process is by inputting the model from CAD software, defining materials, input constraints and vector styles, meshing process, and finally the solution process. From the simulation results, it will be known the value of the solution in the form of stress, deformation and safety factor of the upright component. From several topology optimization designs, they will be compared to find out which is the best design which will be used as a design recommendation.
