چکیده

ABSTRAK Rangka atau sasis adalah bagian penting dari sebuah kendaraan yang memiliki fungsi untuk menopang semua beban, mulai sistem penggerak, kemudi, suspensi, rakitan gandar, pengereman hingga penumpang dan bagasi. Sasis harus bisa menjaga komponen bertumpu di atasnya tetap berada pada dudukannya. mampu memberikan kekuatan, fleksibilitas, stabilitas dalam berbagai kondisi operasi. juga kekakuan terhadap beban bending maupun torsi serta sangat handal keamanan kepada penumpangnya. Dalam penelitian ini, dibuat mobil listrik tipe tubular space frame Kompetisi Mobil Listrik Indonesia (KMLI). Bahan digunakan pipa baja UOE dengan diameter 1 inci. ini selanjutnya diuji metode uji mengetahui kekakuannya. Dari proses pembuatan didapatkan dimensi sesuai rancangan telah sebelumnya. Sedangkan pengujian dilakukan, diketahui bahwa defleksi terbesar terjadi 3,2 mm 125 kg. Dan hasil perhitungan diperoleh angka 41,66 kg/mm. Kata kunci: sasis, frame, pengelasan, kekakuan. ABSTRACT Chassis is an automotive component that functions to support all loads, starts from the traction system, steering suspension axle assembly, braking and also passengers luggage. The chassis must be able ensure components stick on it are in correct position. provide strength, flexibility stability of vehicle under various operating conditions. have rigidity against torsional loads very reliable security passengers. In this research, a type electric car was made for Indonesian Electric Car Competition material used steel pipe with inch. This then tested using test method determine its stiffness. From manufacturing process has been carried out, obtained dimensions accordance design previous studies. tests known largest deflection occurs 3.2 at load And calculation stiffness 41.66 Keywords: Chassis, welding process,

Interactive Analysis of Space Frame Raft Soil System

This study presents a new approach for physical and material modeling of space frame-raft-soil system. The physical modeling consists of a modified Thimoshenko beam bending element with six degrees of freedom per node to model the beams and columns of the superstructure, a modified Mindlin's plate bending element with five degrees of freedom per node to represent the structural slabs and raft, ...

Parallel Transport Frame in 4 -dimensional Euclidean Space

In this work, we give parallel transport frame of a curve and we introduce the relations between the frame and Frenet frame of the curve in 4-dimensional Euclidean space. The relation which is well known in Euclidean 3-space is generalized for the …rst time in 4-dimensional Euclidean space. Then we obtain the condition for spherical curves using the parallel transport frame of them. The conditi...

On the Curvatures of Tubular Surface with Bishop Frame

A canal surface is the envelope of a moving sphere with varying radius, defined by the trajectory C(t) (spine curve) of its center and a radius function r(t) and it is parametrized through Frenet frame of the spine curve C(t). If the radius function r(t) = r is a constant, then the canal surface is called a tube or tubular surface. In this work, we investigate tubular surface with Bishop frame ...

Mobil Uygulamalarin Kalite Ozelliklerinin Olcumu

Since it is difficult to measure the (external) quality attributes of a software product directly, an evaluation is made by using some software metrics that represent the value of related internal quality attributes. The objective of this work is to answer the research question – which has not been studied much in the literature yet – of whether the quality attributes of an application will be ...
