The synthesis of the kinematic chain needs to obtain information accurately and comprehensively. Isomorphism identification is an essential step in synthesis. In this article, a novel isomorphism determination method planar chains with multiple joints based on joint–joint matrix description was proposed. First, presented describe chain, which can uniquely represent structure. Then links were extracted from matrix. And link code joint introduced attributes attributes, respectively....
Uneven current density distribution in a proton exchange membrane fuel cell (PEMFC) can decrease the reactant and catalyst utilization, reduce energy conversion efficiency of whole cell, even lead to shortened life. Therefore, studying has critical role research development PEMFC. To investigate cells' local under different operating conditions, single using segmented technique consisting 36 zones was designed. The results show that maximum first appears at outlet then moves inlet. In...
During the process of kinematic structure enumeration using graph theory, isomorphism identification graphs is an important and complicated problem. In this paper, improved hamming number method (IHNM) was proposed to detect for chain with multiple joints. Firstly, it difficult deal joints in mechanism analysis synthesis, so joint-joint matrix used describe chain. The can uniquely represent Then, Hamming obtained by method. joint number, string were introduced, which determine whether...
Traditional refractory high-entropy alloys (RHEAs) generally exhibit a trade-off between high-temperature strength and light weight. In present work, novel design strategy based on tailoring element distribution is proposed to achieve excellent at density lower than 7 g·cm-3. Specifically, Ti40Nb15Mo30(NbC)15 composite was designed prepared by powder metallurgy. The found be composed of two ultrafine-grained (UFG) phases including body-centered cubic (bcc) solid-solution phase face-centered...
Abstract. Metamorphic mechanisms belong to the class of that are able change their configurations sequentially meet different requirements. In this paper, a holographic matrix representation for describing topological structure metamorphic was proposed. The includes adjacency matrix, incidence links attribute and kinematic pairs attribute. Then, expanded is introduced, which driving link, frame link identifier configurations. Furthermore, an original mechanism proposed, has ability evolve...
In an air-cooled proton exchange membrane fuel cells (PEMFC) stack, air fan provides the reaction gas and cools making thermal management more difficult. Improper will cause poor stack performance or decrease lifetime even lead to thermorunaway in PEMFC stack. The temperature characteristics must be studied optimise of PEMFC. this study, effect supply method, flow output current on stacks were experimentally investigated by a multizone measurement method. results showed that highest was...
Abstract Porous TiAl intermetallic compound is a material with excellent properties, which could be applied to various fields. However, the disadvantage of current porous intermetallics that permeate flux low. In this paper, (NH 4 ) 2 CO 3 was selected as pore-forming agent fabricate by activation reactive sintering. After that, effect pore former content and mechanism were investigated. The results indicated benefit for formation through-holes in intermetallics, Kirkendall partial diffusion...
