Keywords: Articulated vehicles Bluff bodies Road vehicle aerodynamics Square back vehicles Wake flow Wind tunnel tests a b s t r a c t An experimental study has been conducted to investigate both the time-averaged and instantaneous flow pattern over a scale articulated vehicle model for understanding the flow physics of tractor-trailer vehicles. Fully turbulent flow was used in the study and sm...

In addition to having methods for depopulation of commercial poultry flocks to contain outbreaks of serious avian disease, there is need to have an efficient and humane method to dispose of small flocks that might fall within an affected area. A modified atmosphere killing (MAK) chamber mounted on a trailer to be pulled by a pickup truck was designed for small flock depopulation. The atmosphere...

In this paper, the kinematic model of an autonomous mobile robot system consisting of a chain of steerable cars and passive trailers with axle-to-axle hitching is examined and converted into a multi-input chained form using dynamic state feedback. Some of the methods which have been proposed for steering two-input chained form systems are generalized to multi-chained systems, and then applied t...

To evaluate the condition of asphalt pavement road, two GPR systems with different frequency band were mounted in the trailer type vehicle. The GPR system with higher frequency band was used to measure the thickness of the asphalt layers and the other system with lower frequency band was used to detect the air cavity located beneath the asphalt pavement.

This article presents a new kind of navigation system for agricultural machines. The focus is on trajectory control where a Nonlinear Model Predictive path tracking for tractor and trailer system is presented. The experiments of the proposed method are carried out by using real agricultural machines in real environ-

Paraformaldehyde powder, depolymerized by heat, produced formaldehyde gas that was effective in sterilizing laboratory rooms, a mobile laboratory trailer, various surfaces, fiberglass filter medium, and specialized laboratory equipment. A sporulating and nonsporulating strain of bacteria, a virus, and a bacterial toxin were used as test agents. The dissemination procedures and equipment, the as...

Convenient and reliable temperature monitoring systems are increasingly demanded in vehicle refrigerators. However, difficulties exist in wiring between temperature recorders and sensors in vehicles such as trailer-tractor. To solve this problem, this paper provides a novel solution: wireless temperature sensors using Bluetooth. A prototype of the wireless temperature sensors has been developed...
