Four-noded, reduced integration shell elements were used, with...

Vehicle drivability is defined as the smoothness of a vehicle's operation at will driver under all driving conditions.Currently, evaluation conducted through subjective ratings-based test standard which derived from established procedures.Human rating can be inconsistent due to physical health conditions and individual preferences.This study determine possibility using longitudinal acceleration arrange an objective assessment.Vehicle vehicle ratings four expert evaluators.A was evaluated...

In automotive industry, thin walled beam is widely used to build vehicles structure. Vehicle structure built by joining beams using various welding techniques. The usage of in important improve vehicle performance offering better strength-to-weight ratio. However the application will cause few drawbacks When or loaded with compression load, at certain limit it undergo local global buckling. Another problem when joined other beams, show unexpected deformation which called joint flexibility....

Rear-roof spoiler is commonly used for improving the aerodynamic performance of road vehicles. This study aims to investigate effect strip-type rear-roof on hatchback The main parameter was inclination angle spoiler. A computational fluid dynamics (CFD) method used. numerically obtained results were compared experimental data validation CFD method. effectively reduced lift at positive by causing surface pressure near roof-spoiler junction increase. However, its unfavourable when configured...

This paper presents wind tunnel experiment on two delta wing configurations which are differentiated by their leading edge profiles: sharp and round-edged wings. The experiments were performed as a part of the aerodynamics research development in Universiti Teknologi Malaysia, low speed (UTM-LST). Steady load balance flow visualization tests conducted at Reynolds numbers 0.5, 1, 1.5 × 10 6 , respectively. measurement number was also 5 m/s. During experiments, laser with smoke visualizations...

The COVID-19 pandemic has had dramatic effects on the socio-economic and well beings of Malaysians. objective study is to find university students both technical side, such as sufficiency infrastructure internet support online teaching learning (T&L), social stress level focus study. nationwide effect Malaysian varsities was conducted at end 2020. There are many important issues uncovered in this ranging from internet-ready programs, psychological perspectives. It shall provide...

The effect of rear-roof spoiler on the aerodynamic drag performance simple hatchback model has been investigated for a range pitch angles. RANS based CFD method was utilized. Validation done by comparing results Ahmed without to experimental data. beneficial influence at positive inclination angle below 5°. Above that angle, increases with angle. mechanism how influences identified through extensive flow visualization.

Thin walled structure is widely used in designing light weight vehicle. For automotive industry, an important characteristic to increase performance of a Vehicle structures are built from thin beams by joining them using various methods and techniques. structure, its stiffness greatly depends on joint stiffness. However, beam difficult predict accurately due buckling effect. Once the joined form it will expose flexibility A lot researches had been done behaviors analytically numerically....
