    <p class="news-item-summary">Mae tîm ymchwil cydweithrediadol sy'n cynnwys Prifysgol Abertawe wedi ennill grant gwerth dros £4 miliwn i greu offer dylunio anlinellol deinamig newydd ar gyfer strwythurau peirianegol.</p>

    <div class="news-item-content">
        <p align="center" style="text-align: left;">Mae'r t&icirc;m, a arweinir gan Brifysgol Bryste yn gweithio ar y cyd &acirc; Phrifysgolion Abertawe, Caergrawnt, Sheffield, a Southampton, wedi derbyn grant &pound;4.2 miliwn ar gyfer y rhaglen oddi wrth y Cyngor Ymchwil Peirianneg a'r Gwyddorau Ffisegol. Nod y prosiect yw sicrhau newid mawr o ran deall ac ymelwa ar anlinoledd mewn systemau strwythurol deinamig i lunio cenhedlaeth newydd o offer dylunio anlinellol deinamig.</p>
<p>Rheolir perfformiad strwythurau peirianegol gan y ffordd y maent yn ymddwyn yn eu hamgylchedd gweithredol. Mewn llawer o achosion, megis cynhyrchu trydan o wynt neu donnau, roboteg feddygol, awyrofod, a strwythurau sifil mawr, mae gan effeithiau anlinellol deinamig ddylanwad mawr ar y perfformiad gweithredol. Fodd bynnag, mae deall ac ymelwa ar effeithiau anlinellol mewn deinameg strwythurol yn codi anawsterau difrifol, ac yn rhwystr i gynnydd y dylunio ar lawer o strwythurau.</p>
<p>Dywedodd yr Athro Mike Friswell o Goleg Peirianneg Prifysgol Abertawe, "Mae'r grant hwn wedi rhoi hwb sylweddol i'r prosiect ac mae'r t&icirc;m yn edrych ymlaen at ddatblygu technegau modelu a rheoli arloesol y gellir eu defnyddio'n uniongyrchol yn y broses o ddylunio systemau strwythurol, ac y bydd y grŵp yn eu dangos ar waith mewn cyfres o arddangosiadau arbrofol diwydiannol. Bydd yr offer dylunio hyn yn caniat&aacute;u trawsnewid perfformiad systemau strwythurol peirianegol sy'n wynebu gofynion cynyddol oherwydd pwysau technolegol, economaidd, ac amgylcheddol."</p>
<p>Arweinir y t&icirc;m ymchwil gan David Wagg, Athro Deinameg Strwythurol yn yr Adran Peirianneg Fecanyddol ym Mhrifysgol Bryste, gyda chefnogaeth partneriaid gan gynnwys Stirling Dynamics, EDF Energy, Airbus UK, GL Garrad Hassan, Rolls-Royce, Romax Technology, AgustaWestland, ac ESI Group.</p>
<p>Dywedodd yr Athro David Wagg, "Mae cymhlethdod dyluniadau modern wedi tyfu'n gyflymach na'n gallu i lwyr ddeall eu hymddygiad deinamig. Hyd yn oed gyda chymorth cyfrifiaduron nerthol dros ben, sydd wedi galluogi peirianwyr i wneud efelychiadau manwl, mae dehongli canlyniadau'r efelychiadau'n rhwystr sylfaenol.&nbsp; Ymddengys nad yw ein gallu i wireddu canlyniadau arbrofol yn gwella, yn bennaf oherwydd y cyfuniad o effeithiau ar hap ac ansicr, a methiant yr ymagwedd arosod linellol.</p>
<p>"O ganlyniad, mae angen math newydd o ddeinameg strwythurol ar frys, sy'n ymgorffori anlinoledd yn drwyadl, er mwyn caniat&aacute;u i ni ddylunio a chynhyrchu'r genhedlaeth nesaf o strwythurau peirianegol.</p>
<p>"Mae anlinoledd yn digwydd yn naturiol mewn llawer o sefyllfaoedd, ond er gwaethaf hynny, mae pobl wedi'i osgoi'n draddodiadol wrth ddylunio systemau peirianegol. Fodd bynnag, mae pwysau mawr ar allu dyluniedig pob strwythur peirianegol i ymateb i'r angen brys yn y gymdeithas sydd ohoni i ddod o hyd i atebion technolegol i broblemau byd-eang megis newid hinsawdd. O ganlyniad, mae deall a rheoli anlinoledd yn gynyddol bwysig mewn llawer o sefyllfaoedd lle ddefnyddir peirianneg. Un enghraifft losg ar hyn o bryd yw deinameg tyrbinau gwynt mawr. Mae deall anlinoledd yn hanfodol er mwyn sicrhau bod gennym strwythurau diogel, dibynadwy, ac effeithlon."</p>
