Many researches on vehicle planar motion stability focus on two degrees of freedom(2DOF) vehicle model, and only the lateral velocity (or side slip angle) and yaw rate are considered as the state variables. The stability analysis methods, such as phase plane analysis, equilibriums analysis and bifurcation analysis, are all used to draw many classical conclusions. It is concluded from these rese...

BACKGROUND & OBJECTIVES The district of Thiruvananthapuram reports the maximum number of cases of dengue in the state of Kerala. To determine the larval diversity, density and breeding site preferences of Aedes mosquitoes, during pre-monsoon and monsoon periods in urban and rural areas of Thiruvananthapuram district. METHODS Based on the daily reports of dengue cases, 70 clusters were identif...

background, aim, method, result) max 200 words: Active safety systems are becoming increasingly common in today’s vehicles. Electronic Stability Control (ESC) systems were introduced during the end of the 1990s, and accident statistics show that they have had a huge impact on traffic safety. The objective of this study was to suggest a (prototype) test method that can be used for holistic evalu...

The fatigue life of orthotropic steel bridge decks in road bridges depends on the load effects exerted by heavy lorries. contact surface tyres is one important variables. Measurements described literature demonstrate that actual tyre surfaces today’s traffic representative for Europe are shorter and slightly wider than defined model European standard loads — EN 1991-2. This paper derives a new,...

Used tyres pose a threat to the environment, especially in developing countries, since current disposal methods lead environmental pollution. Pyrolysis liquid from used can be as source of fuel replace petroleum diesel. Microwave pyrolysis is an alternative valorization process that supposed save energy and, therefore, environment friendly. In study, microwave was produce fuel. Processing varia...

The air quality in Sweden is strongly influenced by the geographic location and the climate in the northern part of Europe. During wintertime, the temperature is often below zero degree and rain and snow are common which cause slippery roads and needs for house heating. For anti-skid treatment, studded tyres and sand are frequently used which create a lot of road wear particles. Residential woo...

Selecting the appropriate tyre configuration and settings for heavy farm vehicles is important to ensure that soil compaction power loss in rolling resistance are minimised traction optimised. This study investigated effect of front-wheel assist (FWA, ≈75 kN) four-wheel drive (4 WD, ≈100 tractors fitted with different configurations (single, dual), sizes inflation pressures on strength (a proxy...
