چکیده
Abstract In order to meet the requirements of heavy off-road vehicles for long-stroke elastic elements, a new type double-chamber hydro-pneumatic spring was innovatively designed. According structure and working characteristics, mathematical models under two conditions are established, its stiffness characteristics analyzed. The force displacement data at different frequencies were obtained by rig test. static friction, damping separated. Based on displacement, polytropic exponent is identified curve fitting. theoretical model designed in this paper provide support application vehicle.

Design and analysis of a thermoelectric generator for a heavy-duty vehicle in real road test
Heavy duty vehicles have a great share on fossil fuel consumption and greenhouse gases in the world, while they waste two third of chemical energy of fuel. On the other hand, simplicity and long life of thermoelectric generators (TEGs) are considered more and more to convert thermal energy to electrical one. In this paper a TEG designed in the exhaust system of Renault Midlum 195 Dxi Engine. Th...
