Existing network planning models for electric vehicle (EV) services usually treat the battery swap and on-board supercharging as two independent processes. This study makes an early attempt to design EV charging where are jointly coordinated. The supercharge processes characterized by Erlang B C priority queues, respectively. A strategic location-allocation model is formulated optimize station ...

Hydraulic rubber hoses are subject to great hydraulic impact during the actual working process, which causes a potential safety hazard. Therefore, it is necessary carry out pressure tests on hose assemblies ensure its quality, so providing high for has become key technology of this problem. Aiming at solving problem detection resistance in cleaning machines, paper analyzed pressurization mechan...

Compressor performance is ioiluenced by many factors. Besides the commonly considered factors such as suction gas heating, leakage, compressed gas re-expansion, gas pulsations, and back flow, supercharging effect on performance is also studied. Since the compressor used in this study operates in a wide speed range, from 1100 rpm up to 9000 rpm, how those factors affect the compressor performanc...
