0272-1732/01/$10.00  2001 IEEE Automatic coupling of railway vehicles has existed since the mechanical Jenny coupler at the turn of the 19th century. The railway industry’s next challenge is automatic coupling of the vehicle’s electronic equipment through a data bus. This requires a worldwide standardization of onboard data communication. A joint effort by the International Railways Union (Uni...

    Modeling and identification of the system of Iranian cars is one of the most basic needs of automotive and consumer groups and has a broad role for safe driving. It has happened with speed increasing or changing of shift gear, effects on water temperature or the car's torque has been observed, but how much and how intensely and with what algorithm this effect is identifiable, can be modeled...

This paper proposes guidelines and an approach for assessing and ensuring that the replacement of electrical and electronic parts used in aircraft electrical systems and equipment is addressed safely from the software perspective in the certification process while minimizing manufacturer and operator costs and schedule impacts. Many electronic components used in already certified aircraft syste...

A vehicle for a complete engineering and scientists practical formation is presented. It is made possible by the use of virtual instrumentation, not in the sense of a simulation tool, but as the remote access to facilities located in related research laboratories. Internet World Wide Web provides a best way to materialize this remote access, reducing the requirements in the educational laborato...

This paper describes a new course on 24/7 collaborative engineering and product data management. A key element of this course is to use state-of-the-art hardware and software technologies to deliver live, transatlantic, team-taught joint lectures, and to facilitate synchronous and asynchronous student design collaboration with colleagues overseas: Unigraphics is used for CAD/CAM/CAE; Teamcenter...

In order to remain competitive, the European metal working industry aims for customer-oriented production more and more. That means, the automation of the welding activity in an environment producing customised products has potentially wide-ranging benefits for many other industries such as construction, shipbuilding, off highway vehicle, structural fabrication, military vehicles, and heavy han...

Automotive wiring harness helps the interaction between electrical equipment such as in-vehicle controllers, sensors, actuators, and lamps. An automotive connector, on the other hand, is one of the important parts, which connects wiring harness to other harnesses or electrical devices. Automotive connector terminals are generally made of tin, gold and silver plated copper alloys. Figure 1 shows...

The ball lock separation mechanism is used in space vehicles. Various parts of space vehicles have to be separated during flight, to jettison burnt out rocket stages and components that are no longer needed, to uncover equipment, or to deploy payloads. In this paper the detailed analysis of a „Ball Lock release mechanism‟ designed to meet customer specific conditions is presented. Multi-body si...

Pedestrians are among the most vulnerable road users. Speed of vehicles is considered as one of the major causes of danger for pedestrians crossing the street. Therefore, it is of utmost importance to devise suitable solutions to reduce speed of vehicles. One of these solutions is installation of Pedestrian Refuge Islands (PRI) in very wide midblocks. With regard to fluctuations in pedestrian a...
