This study discusses the design of a car rim and analyzed its mechanical properties using three different basic materials: aluminum, steel, titanium. The purpose this is to reduce production time minimize risk failure. In Catia software rim, then simulate effect applying force on component, certain working pressure, able perform calculations display results for analysis. analytical method used ...

The intake port of a CA4DD diesel engine was investigated by computational fluid dynamics (CFD) numerical simulation to enhance the swirl and improve flow characteristics in engine. uniform design method applied study influence guide vanes with different parameters on process at various valve lifts. Nine vane models were established compared base model using CATIA™ 3D CAD software. Numerical si...

This study aims to improve the vehicle vertical dynamics performance in sprung and unsprung state for in-wheel-motor-driven electric vehicles (IWMD EVs) while considering unbalanced magnetic force effects. An integrated vibration elimination system (IVES) is developed, containing a dynamic vibration-absorbing structure between IWM suspension. It also includes an active suspension based on delay...

Fused deposition modeling (FDM) is a capable technology based on wide range of parameters. The goal this study to make comparison between infill pattern and density generated by computer-aided design (CAD) FDM. Grid, triangle, zigzag, concentric patterns with various densities following the same structure FDM machine were designed CAD software (CATIA V5®). Polylactic acid (PLA) material was ass...

Scope Nowadays, a new era of orthopedic surgery is taking place. Procedures like ultrasound-guided interventions, invasive pain orthopaedics started to be widely performed. Objective The aim the project virtual development needle-knife surgical device useful for minimally orthopaedic procedures and other procedures. Method Three different needle devices were compared. One base model 1 two are e...

By using more complexity automobile products, the quantities of requirements to the development process are largely placed. The concept of this work aims to minimize the costing and development times, and to increase the quality of products. The efficient reuse of knowledge in the early development phases requires the support of a template based explicit, structured and consistent model. This m...
