Njengesixhobo sothumelo, izixhobo zeplanethi zisetyenziswa ngokubanzi kwiindlela zobunjineli ezahlukeneyo, ezifana nesinciphisi segiya, ikhreyini, isinciphisi segiya yeplanethi, njl.njl. Kwisinciphisi segiya yeplanethi, inokutshintsha indlela yokuhambisa uloliwe we-axle esisigxina kwiimeko ezininzi. Kuba inkqubo yokuhanjiswa kwegiya kukufowunelwa komgca, ixesha elide lokuhlangana kuya kubangela ukusilela kwegiya, ngoko ke kuyafuneka ukulinganisa amandla ayo. ULi Hongli et al. wasebenzisa indlela ye-meshing ezenzekelayo yokudibanisa igiya yeplanethi, kwaye wafumana ukuba i-torque kunye noxinzelelo oluphezulu luhambelana. Wang Yanjun et al. Ikwadibanise igiya yeplanethi ngendlela yokuvelisa ngokuzenzekelayo, kwaye yalinganisa i-statics kunye nokulinganisa kwemodyuli yegiya leplanethi. Kweli phepha, izinto ze-tetrahedron kunye ne-hexahedron zisetyenziselwa kakhulu ukwahlula i-mesh, kwaye iziphumo zokugqibela zihlalutya ukuze zibone ukuba iimeko zamandla zidibene.

1, Ukusekwa komzekelo kunye nohlalutyo lweziphumo

Imodeli enemigangatho emithathu yezixhobo zeplanethi

Izixhobo zeplanethiubukhulu becala yenziwe ngesixhobo sokukhala, izixhobo zelanga kunye nezixhobo zeplanethi. Iiparamitha eziphambili ezikhethiweyo kweli phepha zezi: inani lamazinyo kwindandatho yangaphakathi yegiya yi-66, inani lamazinyo e-sun gear yi-36, inani lamazinyo eplanethi yeplanethi yi-15, ububanzi bangaphandle begiya yangaphakathi. Umsesane yi-150 mm, i-modulus yi-2 mm, i-angle yoxinzelelo yi-20 °, ububanzi bezinyo yi-20 mm, i-addendum yobude bomlinganiso ngu-1, i-backlash i-coefficient yi-0.25, kwaye kukho iigiya ezintathu zeplanethi.

Uhlalutyo lokulinganisa oluzinzileyo lwezixhobo zeplanethi

Chaza iipropathi zezinto eziphathekayo: ngenisa inkqubo yegiya yeplanethi enemigangatho emithathu ezotywe kwi-software ye-UG kwi-ANSYS, kwaye usete iiparamitha eziphathekayo, njengoko kubonisiwe kwiThebhile 1 ngezantsi:

I-Meshing: I-mesh ye-finite element yahlulwe nge-tetrahedron kunye ne-hexahedron, kwaye ubungakanani obusisiseko be-elementi yi-5mm. Ukususela kwiizixhobo zeplanethi, i-sun gear kunye nendandatho yangaphakathi idibene kunye ne-mesh, i-mesh ye-contact kunye ne-mesh parts igxininiswe, kwaye ubukhulu buyi-2mm. Okokuqala, iigridi ze-tetrahedral zisetyenziswa, njengoko kuboniswe kuMfanekiso 1. Izinto ze-105906 kunye ne-177893 nodes zenziwa ngokupheleleyo. Emva koko igridi ye-hexahedral yamkelwa, njengoko kuboniswe kuMfanekiso 2, kunye neeseli ze-26957 kunye ne-140560 nodes zenziwa ngokupheleleyo.

Ukusetyenziswa komthwalo kunye neemeko zomda: ngokweempawu zokusebenza zegiya leplanethi kwisinciphisi, igiya yelanga sisixhobo sokuqhuba, igiya leplanethi lisixhobo esiqhutywayo, kwaye isiphumo sokugqibela sithwala iplanethi. Lungisa i-ring gear yangaphakathi kwi-ANSYS, kwaye usebenzise i-torque ye-500N · m ukuya kwi-sun gear, njengoko kuboniswe kwi-Figure 3.

Ukusetyenzwa kwesithuba kunye nohlalutyo lweziphumo: I-nephogram yokufuduswa kunye nephogram yoxinzelelo olulinganayo lohlalutyo olusisigxina olufunyenwe kulwahlulo lwegridi ezimbini lunikwe ngezantsi, kwaye uhlalutyo lothelekiso lwenziwa. Ukusuka kwi-nephogram yokufuduswa kwezi ntlobo zimbini zeegridi, kufumaniseka ukuba ukufuduswa okuphezulu kwenzeka kwindawo apho igiya lelanga lingadibanisi negiya leplanethi, kwaye uxinzelelo olukhulu lwenzeka kwingcambu ye-gear mesh. Uxinzelelo oluphezulu lwegridi ye-tetrahedral yi-378MPa, kwaye uxinzelelo oluphezulu lwegridi ye-hexahedral yi-412MPa. Ekubeni umda wesivuno sezinto eziphathekayo yi-785MPa kunye nokhuseleko lwe-1.5, uxinzelelo oluvumelekileyo yi-523MPa. Uxinzelelo oluphezulu lweziphumo zombini lungaphantsi koxinzelelo oluvumelekileyo, kwaye zombini zihlangabezana neemeko zamandla.

2, Isiphelo

Ngokusebenzisa i-finite element simulation yegiya yeplanethi, i-displacement deformation nephogram kunye nephogram yoxinzelelo olulinganayo lwenkqubo yegiya ifunyenwe, apho ubuninzi kunye nobuncinci bedatha kunye nokusabalalisa kwaboizixhobo zeplanethiimodeli inokufumaneka. Indawo yoxinzelelo oluphezulu olulinganayo yindawo apho amazinyo egiya anokuthi angaphumeleli, ngoko ke ingqalelo ekhethekileyo kufuneka ihlawulwe kuyo ngexesha loyilo okanye lokuvelisa. Ngokuhlalutya inkqubo yonke yezixhobo zeplanethi, impazamo ebangelwa kuhlalutyo lwezinyo legiya enye iyoyiswa.
