Humping mechanisms present in high speed welding

Science and Technology of Welding and Joining, 2006
As welding speeds continually increase owing to automation and newer processes, a common defect that occurs is humping. Humping is the periodic occurrence of beadlike protuberances. The objective of the present investigation is to review current and previous researches that were made on humping, including both experimental and theoretical studies.

Optimal road hump for comfortable speed reduction

SPIE Proceedings, 2008
We propose a practical tool for exploring the dynamic relation between road profiles and vehicle motion in the time domain. It is symmetric in the sense that the direct (vehicle response to a given road profile) and the inverse (ideal road profile for a given response) problems are both solved by means of digital filtering. The dynamics of each vehicle

The Best Speed Limit Range for Road Hump

Applied Mechanics and Materials, 2014
Through simulating the process of vehicle running over humps in CarSim, calculating and analyzing the body vertical acceleration, the wheel load and wheel ground adhesion index for the car with different speeds that runs over road humps having different height and width, so as to obtain the effect of height and width of the hump on the deceleration ...

Humping reduction methods for high speed laser welding

ICALEO 2009: 28th International Congress on Laser Materials Processing, Laser Microprocessing and Nanomanufacturing, 2009
Conventional pulsed laser welding is typically done at speeds on the order of millimeters per second, which is too slow to be economically feasible for future energy applications such as laser welding bipolar plates for fuel cells. A typical fuel cell stack may have hundreds of feet of welding which must be executed with high precision and no defects ...

Evaluation of speed humps and tables in Qatar

Journal of Local and Global Health Science, 2015
Controlling the speed of vehicles on various roads and streets is crucial in order to maintain the safety of people and to prevent any possibility of injury or death. One technique that is widely used in Qatar to force road users to reduce their vehicles’ speed is the installation of speed humps and tables.

Study of Geometric Design of Rubber Speed Control-Hump

CICTP 2012, 2012
Rubber speed control-hump is widely used because it is simple and effective. However, there is no specific design specification in the actual application which result in a lot of potential safety hazards and noise pollution. Different geometric design of speed control-hump will bring different effects of deceleration and noise.
