Based on ADAMS CAR module, and the establishment of four - wheel steering vehicle virtual prototype model of the Motor Vehicles ( the WS ). Front and rear comer is proportional to the control strategy, the angle step experimental simulation model and simulation results are analyzed. The results showed that 4WS cars can improve low speed maneuverability and high speed stability, but high speed likely to increase driver fatigue strength.
In this paper, we proposed a predator-prey system incorporating Rosenzweig functional response and prey refuges. We will consider the stability property of the equilibria. Our results show that refuges using by prey have stabilizing effect on the considered system.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
