Abstract

Saat go-kart berada di lintasan balap, kendaraan ini diharuskan memiliki akselerasi dan kecepatan yang tinggi. Karena lintasan untuk perlombaan go-kart tidak hanya lintasan yang lurus, melainkan terdapat beberapa belokan dari sudut belok yang tumpul hingga tajam. Karena itu go-kart juga harus dapat melaju dengan kecepatan tinggi saat berbelok. Tetapi, go-kart pada umumnya tidak dilengkapi dengan sistem differential gear dan suspense seperti pada kendaraan balap yang lain. Padahal fungsi dari differential gear ini untuk mengatur agar roda belakang bagian dalam dapat berputar dengan kecepatan sudut yang sama dengan roda belakang bagian luar ketika berbelok. Untuk mengatasi hal ini go-kart didesain sedemikian rupa sehingga roda belakang bagian dalam dapat terangkat pada saat berbelok. Fenomena ini biasanya disebut oleh beberapa komunitas go-kart sebagai efek jacking. Pada penelitian ini terdapat beberapa penelitian terdahulu yang digunakan untuk acuan. Yang pertama, Muhammad Irsyaduddin (2018) yang melakukan penelitian mengenai Chassis Go-Kart untuk mengetahui bagaimana karakteristik kekuatan dan fleksibilitas dengan cara memberi beban vertical dan torsional pada chassis go-kart tipe Birrel, Tony Kart, dan Arrow. Yang kedua, Yulian Dwi Satria Wibisana (2018) yang melakukan penelitian mengenai Torsional Rigidity dan pengaruh dari kekakuan chassis Go-kart ¬terhadap efek Jacking. Pada penelitian ini akan dilakukan dengan menambahkan axle pada chassis agar hasil yang dihasilkan mendekati kondisi nyata. Penelitian ini akan menggunakan Metode Elemen Hingga (MEH). Dimana axle go-kart dan komponen pendukung seperti bearing, hub, dan housing bearing akan dimodelkan menggunakan software 3D Modelling, kemudian di assembly dengan 3D Model chassis tony kart. Setelah itu hasil assymbly 3D Model disimulasi dengan diberikan pembebanan torsional, sehingga akan menghasilkan besar torsional rigidity dan nilai kekakuannya. Dan untuk pembebanan belok, digunakan untuk mengetahui efek jacking dari hasil assembly 3D Model dari chassis dan axle Go-kart. Setelah simulasi dilakukan, hasil memperlihatkan bahwa Axle Soft adalah Axle yang paling fleksibel dengan nilai kekakuan sebesar 51617,949 N/m. Dan Axle yang paling kaku yaitu Axle Hard dengan nilai torsional rigidity sebesar 53812,923 N/m. Dan nilai ini mempengaruhi nilai torsional rigidity dari Chassis Tony Kart, dengan perbedaan Chassis Tony Kart dengan tambahan Axle Soft dibandingkan Chassis Tony Kart tanpa Axle sebesar 25,384 Nm/deg. Selain itu nilai torsional rigidity ini juga mempengaruhi Jacking yang terjadi, didapatkan Jacking Chassis Tony Kart dengan tambahan Axle Soft lebih besar dibandingkan Chassis Tony Kart tanpa Axle dengan besar perbedaaan sebesar 1,96 mm pada kondisi belok ke kiri, dan 4,22 mm pada kondisi belok ke kanan.

When go-karts are on the racing track, this vehicle is required to have high acceleration and speed. Because the track for the go-kart race is not only a straight track, but there are a number of turns from a blunt to the sharp turning angle. Because of that, go-karts must also be able to drive at high speed when turning. However, go-karts in general are not equipped with a differential gear system and suspense as in other racing vehicles. Though the function of the differential gear is to regulate the inner rear wheel can rotate with the same angular speed as the outer rear wheel when turning. To overcome this, the go-kart is designed in such a way that the rear wheels inside can be lifted when turning. This phenomenon is usually referred to by some go-kart communities as a jacking effect. In this study, there were several previous studies that were used for reference. The first is Muhammad Irsyaduddin (2018) who conducted research on the Chassis Go-kart to find out the characteristics of strength and flexibility by giving vertical and torsional loads to the Birrel, Tony Kart and Arrow type of go-kart chassis. The second, Yulian Dwi Satria Wibisana (2018), conducted a study on Torsional Rigidity and the effect of the rigidity of the Go-kart chassis on the Jacking effect. This research will be carried out by adding axles to the chassis so that the results are close to the real conditions. This study will use the Finite Element Method (MEH). Where the go-kart axle and supporting components such as bearings, hubs, and housing bearings will be modeled using 3D Modeling software, then assembled with a 3D Tony Kart Chassis model. After that, the 3D Model assembly results are simulated by giving torsional loading so that it will produce a large torsional rigidity and stiffness value. And for turn loading, it is used to determine the jacking effect of the 3D Model assembly of the Gokart chassis and axle. After the simulation is done, the results show that the Axle Soft is the most flexible Axle with a stiffness value of 51617,949 N/m. And the most rigid Axle is the Axle Hard with a torsional rigidity value of 53812,923 N/m. And this value affects the torsional rigidity of Tony Kart Chassis, with the difference in Tony Kart Chassis with the addition of Axle Soft compared to Tony Kart Chassis without Axle at 25,384 Nm/deg. In addition, the torsional rigidity value also affects the Jacking that occurs, the Jacking of Tony Kart Chassis is obtained with the addition of the Axle Soft larger than the Tony Kart Chassis without Axle with a difference of 1,96 mm in the condition of turning left, and 4,22 mm under conditions turn right.
