Pob zeb diamond ncig saw hniav muaj cov yam ntxwv zoo heev ntawm cov qauv phaj nyias, thiab nws yooj yim rau deformation thaum lub sij hawm sawing, uas cuam tshuam rau lub zog ruaj khov thaum ua. Txhawm rau txheeb xyuas qhov ruaj khov ntawm cov pob zeb diamond ncig pom cov hniav, nws feem ntau pib los ntawm lub xeev kev nyuaj siab, lub ntuj zaus thiab cov khoom tseem ceeb ntawm cov saw hniav thaum ua haujlwm. Muaj ntau yam txheej txheem uas cuam tshuam rau cov ntsuas saum toj no, xws li pom cov hniav sib hloov ceev, clamping flange txoj kab uas hla, saw hniav thickness, saw hniav txoj kab uas hla thiab sawing qhov tob, thiab lwm yam.. xaiv los ntawm kev ua lag luam. Los ntawm kev hloov cov txheej txheem tseem ceeb, cov txheej txheem kev txheeb xyuas qhov kawg thiab qhov sib txawv ntawm qhov sib txawv ntawm cov txheej txheem yog siv kom tau txais cov kev cuam tshuam ntawm cov txheej txheem tseem ceeb ntawm lub xeev kev ntxhov siab, lub ntuj zaus thiab qhov tseem ceeb ntawm lub voj voog saw hniav, thiab tshawb xyuas thiab ua kom zoo dua. Cov txheej txheem tseem ceeb tsis zoo los txhim kho lub zog ruaj khov ntawm cov saw hniav. Lub hauv paus theoretical ntawm kev sib deev.

1.1 Kev cuam tshuam ntawm clamping disc txoj kab uas hla ntawm saw hniav kev nyuaj siab.

Thaum qhov kev sib hloov ceev ntawm lub voj voog saw hniav raug xaiv raws li 230 rad / s, txoj kab uas hla ntawm lub phaj clamping

70mm, 100mm thiab 140mm feem. Tom qab finite element tsom xam, chav tsev node kev nyuaj siab ntawm saw hniav

yog tau nyob rau hauv txawv clamping disc txoj kab uas hla txwv, raws li qhia nyob rau hauv daim duab 5b. Raws li txoj kab uas hla ntawm

clamping phaj nce, qhov kev ntxhov siab ntawm chav tsev ntawm cov saw hniav nce; txawm li cas los xij, thaum muaj kev txwv

ntau yam ntawm cov phaj clamping npog plaub lub suab nrov txo qhov ntawm cov saw hniav [10-12], tus nqi kev ntxhov siab

txo nrog qhov nce ntawm txoj kab uas hla ntawm lub phaj clamping.

1.2 Qhov cuam tshuam ntawm saw hniav thickness ntawm saw hniav nyuaj siab

Thaum lub voj voog saw hniav sib hloov ceev raug xaiv ntawm 230 rad / s thiab clamping disk nrog ib txoj kab uas hla.

100 hli raug xaiv los ua kom tiav kev txwv ntawm cov saw hniav, lub thickness ntawm cov saw hniav hloov

thiab lub xeev kev ntxhov siab ntawm chav tsev nodes nrog lub thickness ntawm 2.4 hli, 3.2 hli thiab 4.4 hli ntawm saw hniav yog

soj ntsuam los ntawm finite element. Kev hloov pauv ntawm meta-node kev ntxhov siab yog qhia hauv daim duab 5c. Nrog nce ntawm

lub thickness ntawm cov saw hniav, qhov kev nyuaj siab ntawm kev sib koom ua ke ntawm saw hniav chav tsev yog ho txo.

1.3 Qhov cuam tshuam ntawm saw hniav txoj kab uas hla ntawm saw hniav nyuaj siab

Cov saw hniav sib hloov ceev yog xaiv raws li 230 rad / s, thiab flange phaj nrog txoj kab uas hla ntawm 100 hli yog

xaiv los ua kom muaj kev txwv tag nrho ntawm cov saw hniav. Thaum lub thickness ntawm sawb yog 3.2 hli,

txoj kab uas hla ntawm saw hniav hloov mus rau lub xeev kev nyuaj siab ntawm chav tsev nodes nrog saw hniav diameters ntawm

318 mm, 368 mm thiab 418 mm. Rau finite element tsom xam, qhov kev hloov pauv ntawm chav tsev node kev nyuaj siab yog

qhia hauv daim duab 5d. Nyob rau hauv txoj kev sawing ntawm qhov tsis tu ncua kab ceev, nrog rau qhov nce ntawm txoj kab uas hla ntawm saw

hniav, qhov kev ntxhov siab ntawm kev sib koom ua ke ntawm cov saw hniav tuaj yeem nce ntxiv.

Kev soj ntsuam tsis zoo heev ntawm qhov cuam tshuam ntawm cov txheej txheem saum toj no tsis muaj kev ntxhov siab ntawm cov saw hniav yog

qhia nyob rau hauv Table 3. Nws tuaj yeem pom tias qhov kev hloov pauv ntawm cov txheej txheem tsis ua haujlwm thiab kev ntxhov siab heev

Qhov sib txawv sib xws rau Table 3 qhia tau hais tias qhov ceev ntawm cov saw hniav muaj qhov cuam tshuam loj tshaj plaws ntawm qhov

kev ntxhov siab ntawm kev sib koom ua ke ntawm cov saw hniav, txoj kab uas hla ntawm cov saw hniav thiab thickness ntawm cov saw hniav,

ua raws li qhov cuam tshuam tsawg tshaj plaws ntawm txoj kab uas hla ntawm lub phaj clamping. Kev sib raug zoo ntawm saw hniav

kev ua haujlwm ruaj khov thiab kev ntxhov siab yog: qhov me dua qhov kev ntxhov siab ntawm cov saw hniav, qhov ua tau zoo dua

stability ntawm saws tes. Los ntawm qhov kev xav ntawm kev txo cov kev ntxhov siab ntawm chav tsev nodes thiab txhim kho cov

kev ruaj ntseg ntawm cov saw hniav, txo qhov kev sib hloov ceev ntawm cov saw hniav, ua kom cov tuab

ntawm cov saw hniav, los yog txo txoj kab uas hla ntawm saw hniav nyob rau hauv lub xeev ntawm tas li kab ceev txiav tau

txhim kho dynamic stability ntawm sawb; txoj kab uas hla ntawm lub phaj clamping yog bounded los ntawm seb yuav

npog lub qhov txo lub suab nrov, thiab kev ua haujlwm ruaj khov ntawm cov saw hniav sab nraum lub qhov txo lub suab nrov

yog nrog lub phaj clamping. Txoj kab uas hla nce thiab nce, thiab qhov sib txawv yog qhov tseeb ntawm lub suab nrov txo

qhov.
