In the present research, a method to model pose error of machine tool feed system is proposed based on principle minimum potential energy. Firstly, force-moment equilibrium equation established by mechanical analysis. Secondly, force single slider analyzed Hertzian contact theory, and state under action guideway obtained. The elastic displacements in horizontal vertical directions are solved mi...

magnetic levitation (maglev) is amongst the most advanced technologies that are available to the transportation industries. it has already been noticed by decision makers in many countries around the globe. contrary to such high levels of interest, there are no practical algorithms available to the engineers and/or managers to assist them in analyzing economics of the maglev systems. therefore,...

High-speed maglev trains offer competitive journey-times to automobile and air transport in markets of 60–1000 miles but they have potentially adverse noise impacts. This paper considers the noise characteristics of the Shanghai Maglev Train on residents within 300 m to the track. It shows that the system is about 4–8 dBA quieter than other high-speed systems at comparable speeds with their gui...

Recently we have proposed a new transportation system called PRISM (which stands for Program for Individual Sustainable Mobility) to help alleviate traffic congestion and to improve energy efficiency of travel [1]. The system employs privately owned small, dual-mode vehicles that can run on both conventional streets and a dedicated guideway. In this paper we consider an all-electric version for...
