Abstract

Pada era globalisasi, permintaan kendaraan di Indonesia terus meningkat, termasuk kendaraan roda tiga yang fungsional, baik berbahan bakar minyak maupun bertenaga listrik ramah lingkungan. Salah satu aspek penting kendaraan adalah kenyamanan dan stabilitas saat berbelok, yang melibatkan perilaku understeer, oversteer, dan ackerman. Untuk itu, dilakukan analisis stabilitas kendaraan roda tiga E-KEVIK ITS melalui slip, skid, dan guling. Analisis melibatkan berbagai variasi parameter seperti kecepatan, sudut belok, tekanan ban, dan jenis permukaan jalan. Data dikumpulkan untuk mendukung perhitungan awal dan analisis utama stabilitas kendaraan. Penelitian menunjukkan bahwa kendaraan E-KEVIK ITS memiliki stabilitas tinggi dengan selisih kecepatan skid dan guling yang kecil, terutama pada sudut belok 20º dan 30º dengan selisih kurang dari 0,90 km/jam di semua jenis jalan. Pada kecepatan 40–60 km/jam, kendaraan menunjukkan perilaku oversteer, ditandai dengan nilai koefisien understeer negatif. Berdasarkan analisa skid menunjukkan kendaraan cenderung oversteer pada sudut belok 10º dan 20º, serta cenderung understeer pada sudut belok 30º. Kecepatan skid roda depan dan belakang pada jalan aspal kering masing-masing adalah 37,90 km/jam dan 33,72 km/jam pada sudut belok 10º, 28,13 km/jam dan 28,32 km/jam pada sudut belok 20º, dan 23,81 km/jam dan 25,69 km/jam pada sudut belok 30º. Pada jalan tanah kering, kecepatan skid bervariasi antara 32,63 km/jam hingga 20,08 km/jam. Berdasarkan analisa guling menunjukkan kendaraan berperilaku understeer pada setiap sudut belok dengan kecepatan guling berkisar antara 2,61 km/jam hingga 22,18 km/jam. Hasil ini mengindikasikan bahwa E-KEVIK ITS memenuhi kriteria stabilitas tinggi dalam berbagai kondisi operasional.

In the era of globalization, the demand for vehicles in Indonesia continues to increase, including functional three-wheelers, both oil-fueled and environmentally friendly electric-powered. One important aspect of the vehicle is comfort and stability when turning, which involves understeer, oversteer, and ackerman behavior. For this reason, a stability analysis of the ITS E-KEVIK three-wheeled vehicle through slip, skid, and roll was conducted. The analysis involved a wide variety of parameters such as speed, turning angle, tire pressure, and road surface type. Data was collected to support preliminary calculations and the main analysis of vehicle stability. The research shows that the ITS E-KEVIK vehicle has high stability with small skid and roll speed differences, especially at turning angles of 20º and 30º with differences of less than 0.90 km/h on all types of roads. At speeds of 40-60 km/h, the vehicle showed oversteer behavior, characterized by negative understeer coefficient values. Skid analysis showed that the vehicle tended to oversteer at 10º and 20º turning angles and tended to understeer at 30º turning angle. The front and rear wheel skid speeds on dry asphalt roads were 37.90 km/h and 33.72 km/h at 10º turning angle, 28.13 km/h and 28.32 km/h at 20º turning angle, and 23.81 km/h and 25.69 km/h at 30º turning angle, respectively. On dry dirt roads, the skid speed varied from 32.63 km/h to 20.08 km/h. The roll analysis showed that the vehicle behaved understeer at each turning angle with roll speeds ranging from 2.61 km/h to 22.18 km/h. These results indicate that the ITS E-KEVIK meets the criteria for high stability under various operational conditions.
