Abstract

Sistem steering merupakan salah satu hal yang paling krusial dalam mendesain mobil. Pada pendesainan sebuah mobil, desain steering system harus mengacu pada sistem kemudi ideal yang disebut Ackermann. Hal ini sangat penting untuk meminimalkan besarnya steering error pada saat melakukan gerak belok. Dalam hal ini kondisi gerak belok ideal ackerman sangat sulit tercapai pada saat kendaraan berbelok. Salah satu cara yang dapat dilakukan untuk mendekati gerak belok ideal adalah dengan melakukan analisa kinematik tiap link steering. Pada tugas akhir ini dilakukan analisa secara kinematis sistem kemudi rack and pinion pada mobil. Dari analisa kinematis ini didapatkan besarnya steering error yang terjadi yaitu 3.818⁰ . Kemudian, besarnya steering error untuk berbagai variasi posisi rack dan dimensi steering arm akan dianalisa. Hasil penelitian menunjukan jika posisi rack diturunkan menjadi 12.5 cm diatas wheel axis dan dimajukan 2 cm dari posisi semula kemudian sudt steering arm ditambah 6 ⁰ menghasilkan nilai steer ing error yang minimum yaitu 0.938⁰.

Steering system is one of the most crucial part in designing a car . The deign of steering system should be based on ideal steering system called Ackermann . It is very important to minimize the amount of steering error at the time of turning motion. In this case the turning motion of ideal conditions based on Ackermann is very difficult to achieve when the vehicle is turning. One way that can be done to achieve the ideal turning motion is to perform a kinematic analysis of each steering link. This final project discuss about kinematic analysis of steering system with rack and pinion in a car. Kinematic analysis can be obtained amount of steering error that occurred in the steering system which is 3.818⁰. Then, the steering error for a wide variety of positions and dimensions of the steering arm will be analyzed. The results showed, when the position of the rack was lowered to 12.5 cm above the wheel axis and 2 cm in front of the wheel axis, will achieve the minimum steering error value which is around 0.938 ⁰. The results also showed that the position of rack and pinion varied, it will change the value of the steering error.
