A relative velocity method was then used to obtain the aerodynamic forces of a moving vehicle-deck system. The moving effects on the aerodynamic forces on the vehicle-deck system were evaluated. The results show that the movement of the vehicle on the first lane of the bridge deck does ...
If a car moves with a constant velocity, does it also move with a constant speed? Pedro accelerates his 75-gram matchbox car to 20 m/s2. What force does Pedro would apply? Inertia keeps your vehicle moving until what happens? A car is moving at speed of 20 m/s. The e...
The pressure-ward rolling moment has been introduced as a method to assess the running safety of the trains. The results show that the maximum repulsive rolling moment was observed at the 1st vehicle, while the maximum attractive rolling moment was observed at the last vehicle. By comparing the...
Related to forces on: Canadian Forcesforce (fôrs) n. 1. The capacity to do work or cause physical change; energy, strength, or active power: the force of an explosion. 2. a. Power made operative against resistance; exertion: use force in driving a nail. b. The use of physical po...
When a moving vehicle is subjected to cross wind, the aerodynamic loads acting on the vehicle itself depend not only on the mean value of the relative wind... G Tomasini,F Cheli - 《Journal of Fluids & Structures》 被引量: 54发表: 2013年 AN INVESTIGATION OF AERODYNAMIC FORCE MODELLING ...
What are the 4 forces on a plane whilst in flight? Equilibrium An object is said to be in mechanical equilibrium if the net force, as well as net torque on the object, is zero, here we are not saying the force i...
During the searches in al-Shifa Hospital, "an underground tunnel shaft has been found beneath the hospital," Israel Defense Forces (IDF) Spokesman Daniel Hagari said in a press briefing on Thursday night. He said a vehicle with "many ammunition" was also found below the medical center. ...
A three-link robot moving due to controlled dry friction forces that act on the central contact points of the robot with a horizontal rough surface is considered. A mathematical model of the mechanism is developed. Algorithms for the implementation of various types of motion are presented. Numeric...

The influence of wheel/rail contact properties in the vehicle dynamics and adhesion fields is investigated. Current tendency all over the world is to reduce the conicity of wheels with the aim of increasing the speed of trains. Wave-length of moving wheel-set in track for worn wheel-set tyre...
