Senzira yekufambisa, giya repuraneti rinoshandiswa zvakanyanya mumhando dzakasiyana dzeinjiniya, senge gear reducer, crane, planetary gear reducer, etc. Kune yepuraneti giya rekudzikisira, inogona kutsiva nzira yekufambisa yeyakagadziriswa axle giya chitima muzviitiko zvakawanda. Nekuti iyo nzira yekufambisa giya ndeyekusangana kwemutsara, nguva yakareba meshing inokonzeresa kutadza kwegiya, saka zvinodikanwa kutevedzera simba rayo. Li Hongli et al. yakashandisa iyo otomatiki meshing nzira kumesh giya repuraneti, uye akawana kuti torque uye yakanyanya kushushikana ine mutsara. Wang Yanjun et al. zvakare meshed giya repuraneti kuburikidza neiyo otomatiki chizvarwa nzira, uye yakateedzera iyo statics uye modal simulation yegiya repuraneti. Mubepa rino, tetrahedron nehexahedron zvinhu zvinonyanya kushandiswa kupatsanura mesh, uye mibairo yekupedzisira inoongororwa kuona kana mamiriro esimba asangana.

1, Kugadzwa kwemuenzaniso uye kuongororwa kwemhedzisiro

Matatu-dimensional modhi yegiya remapuraneti

Planetary gearinonyanya kuumbwa negiya remhete, giya rezuva uye giya repuraneti. Iwo makuru maparamita akasarudzwa mubepa iri ndeaya: nhamba yemazino emukati giya giya makumi matanhatu nematanhatu, nhamba yemazino ezuva giya makumi matatu nematanhatu, nhamba yemazino egiya repuraneti igumi neshanu, dhayamita rekunze regiya remukati. mhete ndeye 150 mm, iyo modulus 2 mm, iyo yekumanikidza angle i20 °, zino rakafara 20 mm, iyo addendum urefu coefficient i1, backlash coefficient i0.25, uye kune matatu magiya emapuraneti.

Static simulation kuongororwa kwegiya repasi

Tsanangura zvivakwa zvezvinhu: pinza iyo matatu-dimensional yepuraneti giya system yakadhonzwa muUG software muANSYS, uye isa ma parameter, sezvakaratidzwa muTebhurari 1 pazasi:

Meshing: Iyo finite element mesh yakakamurwa ne tetrahedron uye hexahedron, uye saizi yekutanga yechinhu i5mm. Kubva pagiya repuraneti, giya rezuva uye mhete yemukati inobatana uye mesh, mesh yekusangana uye mesh zvikamu zvakadzikiswa, uye saizi i2mm. Kutanga, tetrahedral grids inoshandiswa, sezvinoratidzwa mumufananidzo 1. 105906 zvinhu uye 177893 nodes inogadzirwa muhuwandu. Ipapo hexahedral grid inogamuchirwa, sezvakaratidzwa mumufananidzo 2, uye 26957 masero uye 140560 nodes anogadzirwa zvachose.

Rodha yekushandisa uye mamiriro emuganho: zvinoenderana nekushanda kweiyo giya repasi mune inoderedza, giya rezuva ndiro giya rekutyaira, giya repuraneti ndiro giya rinofambiswa, uye yekupedzisira kuburitsa iri kuburikidza nemutakuri wepasi. Gadzirisa mhete yegiya remukati muANSYS, uye isa torque ye500N · m kune giya rezuva, sezvakaratidzwa mumufananidzo 3.

Kugadziriswa kwemashure uye kuongororwa kwemhedzisiro: Iyo yekutamisa nephogram uye yakaenzana kushushikana nephogram ye static ongororo yakawanikwa kubva kumapoka maviri egidhi anopiwa pazasi, uye kuenzanisa kuongororwa kunoitwa. Kubva pakutamiswa nephogram yemhando mbiri dzegridi, inowanikwa kuti iyo yakanyanya kusimuka inoitika panzvimbo iyo giya rezuva harina mesh negiya renyika, uye kushushikana kwakanyanya kunoitika pamudzi wegiya mesh. Kunyanya kushushikana kwegridi yetetrahedral ndeye 378MPa, uye kushushikana kwakanyanya kweiyo hexahedral grid ndeye 412MPa. Sezvo muganho wegoho wezvinhu uri 785MPa uye iyo yekuchengetedza chinhu 1.5, inotenderwa kushushikana i523MPa. Kunyanya kunetseka kwezvigumisiro zvose zvishoma kudarika kunobvumirwa kunetseka, uye zvose zvinosangana nemamiriro esimba.

2, Mhedziso

Kuburikidza neinogumira chinhu simulation yegiya repuraneti, iyo displacement deformation nephogram uye yakaenzana kushushikana nephogram yegiya system inowanikwa, kubva kune iyo yakanyanya uye shoma data uye kugovera kwavo mugiya repuranetimodhi inogona kuwanikwa. Nzvimbo yekunyanya kuenzana kushushikana inzvimbo zvakare iyo mazino egiya anogona kutadza, saka kutarisisa kwakanyanya kunofanirwa kubhadharwa kwairi panguva yekugadzira kana kugadzira. Kuburikidza nekuongororwa kwehurongwa hwese hwemapuraneti giya, kukanganisa kunokonzerwa nekuongororwa kwegiya rimwe chete zino rinokundwa.
