Study on Friction and Wear Properties of Pantograph Strip/Copper Contact Wire for High-Speed Train
A series of experiments on friction and wear properties of carbon strip rubbing against copper contact wire is performed on high-speed friction and wear tester with electric current. The results show that the friction coefficient is generally maintained between 0.24 and 0.37. In the absence of electric current, the coefficient of friction is higher than that in the presence of electric current....
متن کاملEffect of Contact Pressure and Frequency on Contact Heat Transfer Between Exhaust Valve and its Seat
The hot gases produced by the internal combustion engines passes through the exhaust valve and causes high temperatures in the exhaust valve and its seat. To avoid damaging the exhaust valve, heat must be transferred from the valve to its seat during the contact they make at the opening and closing cycle. Heat transfer rate from the exhaust valve to its seat is a function of many factors. One o...
متن کاملAn optimal servo system based on sliding mode for the contact force of an active pantograph
This paper presents a design method of optimal servo systems based on sliding mode for an active pantograph with flexibility subject to the stiffness variation of the catenary. It is pointed out through our analysis that the flexibility makes the control problem much harder, because it increases not only the freedom of motion but also the relative degree between the control input and the contac...
متن کاملAthletics impulsively traits: A comparison between contact and noncontact sports
The aim ofthisstudy was to investigatedifferentaspects ofimpulsivityin the athletes of contact and non-contactsports. volunteer participants were 60 athletes of contact (age: 25.9±4.6 years) and non-contact (age: 27.6±4.9 years) sports. Participants were asked to complete the Barratt’s Impulsivity Scale (BIS-11) and participate in continuous performance test(CPT). Multivariate analysis of varia...
متن کاملContact Sensing from Force Measurements
This paper addresses contact sensing, i.e. the problem of resolving the location of a contact, the force at the interface and the moment about the contact normals is presented. Called \intrinsic" contact sensing for the use of internal force and torque measurements, this method allows for practical devices which provide simple, relevant contact information in practical robotic applications. Suc...
