Abstract
Sepeda merupakan alat transportasi yang sangat umum dan luas penggunaan nya di dunia yang digunakan oleh semua orang dari berbagai kalangan usia. Tidak hanya sebagai alat tranportasi, sepeda juga menjadi salah satu hobi yang cukup banyak diminati oleh masyarakat dan sudah merupakan gaya hidup bagi sebagian masyarakat. Penelitian ini bertujuan melakukan studi analisis Sepeda Multigender ITS dengan metode multibody dynamics simulation pada sepeda dan karena penting untuk membahas mengenai kestabilan dan kenyamanan sepeda pada kondisi sedang berjalan di permukaan jalan agar dapat mengakomodasi kenyamanan dan kestabilan pesepeda pada saat sepeda sedang dikendarai. Penelitian ini dilakukan dengan Desain dan Simulasi dilaksanakan dengan menggunakan software Matlab SIMULINK dan SOLIDWORKS, Simulink digunakan untuk simulasi multibody dynamics bicycle, software SOLIDWORKS digunakan untuk mengenerate bicycle multibody model, simulasi dilakukan dengan melakukan simulasi dinamis pada sepeda dan pengendara. Penelitian dilakukan untuk mengetahui dan mendapatkan output simulasi dinamis dari sepeda berupa nilai tilt angle. Data yang didapatkan dari hasil simulasi akan di validasi dengan menggunakan persamaan dinamis secara perhitungan analitis. Hasil Analisa Kecepatan sepeda terhadap Kestabilan Sepeda Multigender ITS merupakan perbandingan grafik antara kecepatan terhadap manuver sepeda pada kondisi operasional dan terhadap lama nya durasi pengetesan selama 30 detik (sec) yang dialami sepeda tiap waktunya dengan adanya perbedaan dimana pada sepeda diberi dengan tiga parameter variasi kecepatan yang berbeda, yaitu dengan kecepatan 3 m/s atau 10,8 km/jam, kedua simulasi sepeda disimulasikan dengan kecepatan 6 m/s atau 21,6 km/jam, ketiga simulasi sepeda disimulasikan dengan kecepatan 9 m/s atau 32,4 km/jam dan track sebesar 100 meter dan amplitudo track sebesar 20 m dengan berbelok ke kiri dan ke kanan masing-masing sejauh 2 meter. Pada penelitian ini dapat disimpulkan bahwa nilai respon tilt angle tiap waktu yang dihasilkan pada variasi kecepatan yang semakin tinggi steering angle seiring dengan terhadap amplitudo track dan kecepatan yang lebih tinggi, daripada nilai tilt angle yang didapat pada kecepatan yang lebih rendah. Hal ini menyebabkan kenyamanan yang dialami pesepeda ketika sedang membawa sepeda menjadi lebih tidak nyaman bila dibandingkan dengan kenyamanan pada bersepeda dibawah kecepatan 6 m/s atau 21,6 km/jam. Selisih nilai tilt angle kesuluruhan yang ada pada perbandingan sebesar 3 derajat dimana nilai tilt angle keseluruhan sepeda pada kecepatan lebih tinggi dibandingkan dengan kecepatan lebih rendah.

Bicycles are a very common and widely used means of transportation in the world that are used by all people of various ages. Not only as a means of transportation, bicycles are also one of the hobbies that are quite in demand by the public and have become a lifestyle for some people. This study aims to conduct an analysis study of ITS Multigender Bicycle with the multibody dynamics simulation method on bicycles and because it is important to discuss the stability and comfort of bicycles in conditions running on the road surface in order to accommodate the comfort and stability of cyclists when the bicycle is being ridden. Bicycles are a very common and widely used means of transportation in the world that are used by all people of various ages. Not only as a means of transportation, bicycles are also one of the hobbies that are quite in demand by the public and have become a lifestyle for some people. This study aims to conduct an analysis study of ITS Multigender Bicycle with the multibody dynamics simulation method on bicycles and because it is important to discuss the stability and comfort of bicycles in conditions running on the road surface in order to accommodate the comfort and stability of cyclists when the bicycle is being ridden. This research was carried out with Design and Simulation carried out using Matlab SIMULINK and SOLIDWORKS software, Simulink was used for multibody dynamics bicycle and human body simulation, SOLIDWORKS software was used to generate bicycle multibody models, simulations were carried out by conducting dynamic simulations on bicycles and riders. The research was carried out to find out and obtain the dynamic simulation output of the bicycle in the form of steering angle values. The data obtained from the simulation results will be validated using dynamic equations by analytical calculations. The results of the Bicycle Speed Analysis on the Stability of the ITS Multigender Bicycle are a graphical comparison between the speed of the bicycle maneuver in operational conditions and the length of the test duration of 30 seconds (sec) experienced by the bicycle each time with a difference where the bicycle is given with three different speed variation parameters, namely with a speed of 3 m/s or 10.8 km/h, The two bicycle simulations were simulated with a speed of 6 m/s or 21.6 km/h, the three bicycle simulations were simulated with a speed of 9 m/s or 32.4 km/h and a track of 100 meters and a track amplitude of 20 m by turning left and right by 2 meters each. In this study, it can be concluded that the response value of the steering angle at each time is produced at the variation of the speed that increases the steering angle along with the track amplitude and higher speed, than the steering angle value obtained at the lower speed. This causes the comfort experienced by cyclists when carrying a bicycle to be more uncomfortable when compared to the comfort of cycling below 6 m/s or 21.6 km/h. The difference in the overall steering angle value is in a ratio of 3 degrees where the overall steering angle value of the bicycle at a higher speed compared to a lower speed.
