The lateral acceleration, the vertical acceleration, the derailment coefficient and rate of wheel load reduction increase with the increase of the running speed and all meet the requirements of the current national criteria.
SICATH1.0 type heavy power OCS is specially developed for the new constructed line from Koln-Rhein/Main with minimum running speed of 330km/h, and running speed of 400km/h can be reachable by using a pantograph.
It introduces the principles, principal equipment, hard wares, soft wares and applications of ground automatic passing over of neutral section as well as improving the traffic ability in the existing line, economic benefits and social benefits brought up by raising up the running speed of the train.
Based on the speed of vehicle of the vertical curve, this paper introduces the running speed models of vehicle used as substitutions for the common computing running speed of the vertical curve, then the running speed model fairly corresponding to reality is selected after being compared with another one.
This paper analyzes the power balance for asphalt under the working state, introduces the calculating procedure of the engine power and running speed through the running equation of asphalt spreader, and analyses the power balance using diagrams.
Through a great deal of tests and statisticsget the change rule of truck front axle vertical dynamic load amplitudemean valuemaximum value with the changes of running speed and front axle static axle load under the condition of good and bad asphalt road.
In practical gear design, the "speed factor" is usually employed which is defined as a ratio of the allow-able stress at required running speed of the gear system to the stress at zero speed.
This change in GAP-43/B-50 phosphorylation was correlated with the running speed developed by the animals (r:0.8986, P = 0.015).
Sex pheromone of the American cockroach,Periplaneta americana L., Orthoptera: Blattidae, stimulates positive anemotaxis and increased running speed when presented in an air stream.
Sex pheromone presented in the center of the arena produced a reduction in immobility time and a slight increase in running speed.
The wear and friction behaviour of unreinforced PA66 is dominated mainly by three major features: a critical slip ratio under a fixed load and running speed, macro-transverse cracks and a layer of film on the contact surface.
