Koj puas tau xav paub tias AGV-tus kheej- hnyav li cas 3 tons nrog 5-ton payload- tuaj yeem pib, nres, thiab npog 8 meters hauv 8 vib nas this? Ua tiav qhov kev ua tau zoo no tsis yog tsuas yog yuav tsum muaj kev txhawb nqa tsav muaj zog tab sis kuj xav tau kev tswj hwm kev tswj hwm zoo. Niaj hnub no, peb yuav rhuav tshem cov txheej txheem txheej txheem tom qab tsim qauv no thiab qhia tias peb pab pawg YIKONG Smart tau qhib qhov project no li cas.
1. Tsim Lub Hom Phiaj thiab Cov Txheej Txheem Txheej Txheem
Qhov hnyav tag nrho:8 tons (3 tons tus kheej - hnyav + 5 tons payload)
Kev tshem tawm:8 meters (los ntawm Point A rau Point B)
Lub sijhawm xav tau:Ua tiav qhov pib- nres hauv 8 vib nas this
2. Motion Control Logic: Ntsuas ceev thiab quab yuam
2.1 Siv "Uniform Acceleration - Uniform Deceleration" Motion Mode:
Thawj 4 vib nas this:Ua kom nrawm ntawm qhov chaw nres tsheb mus rau qhov nruab nrab (4 meters).
4 vib nas this kawg:Decelerate los ntawm midpoint mus rau qhov kawg (tseem 4 meters).
Raws li pom nyob rau hauv daim duab, qhov siab tshaj plaws ceev ntawm AGV yog xam raws li:
v=2*s/t=2*4/4=2m/s
2.2 Siv "Uniform Acceleration - Qhov nrawm nrawm - Uniform Deceleration" hom lus tsa suab:
Phase Acceleration:Ceev los ntawm standstill mus rau qhov ceev tsis tu ncua.
Theem ceev tsis tu ncua:Khiav ntawm qhov ceev tsis tu ncua.
Phase Deceleration:Decelerate ntawm qhov ceev tsis tu ncua rov qab mus rau xoom.
Los ntawm daim duab, qhov nruab nrab qhov tsawg kawg nkaus ceev yog:
v=s/t,v=8/8=1m/s
Nco tseg:Yog tias AGV ua haujlwm ntawm qhov ceev nruab nrab qhov tsawg kawg nkaus, nws yuav npog raws nraim 8 meters hauv 8 vib nas this- tawm tsis muaj chaw rau kev nrawm lossis qeeb. Hauv kev xyaum, AGV ceev ntawm 1.2 m / s yog siv los ntsuas.
3. Kev kov yeej ob qhov kev tawm tsam loj: Qhov "Hurdles" rau AGV
Rolling Friction Resistance (Ground Resistance):
Thaum lub AGV tsav log yog nyob rau hauv kev txav, dov kev sib txhuam los rau hauv kev ua si. Nws yog kwv yees li:
F=8000*10*0.03=2400N
Inertial Resistance (Resistance thaum Acceleration / Deceleration):
Qhov no yog muab los ntawm:
F=m × aF=m \\times aF =m × a
(Kev suav yuav txiav txim raws li theem acceleration.)
4. Ntsuam xyuas AGV's Acceleration Traction Force kom kov yeej Inertial Resistance
4.1 Kev ntsuam xyuas ntawm qhov siab tshaj plaws ntawm 2 m / s:
Lub AGV accelerates linearly ntawm 0 m / s mus rau 2 m / s thiab decelerates rov qab mus rau 0 m / s, nrog rau ob qho tib si acceleration thiab deceleration theem kav 4 vib nas this.
Siv qhov sib npaug s=v0t+0.5at2s=v_0 t + 0.5at^2s=v0t+0.5at2 (nrog v0=0v_0=0v0{15}}),
peb pom: a=2*4/4²=0.5m/s²
Lub zog traction yuav tsum tau kov yeej inertial tsis kam yog:
F=ma=8000*0.5=4000N
Yog li, AGV tsav lub log yuav tsum muab lub zog traction ntau dua li qhov sib npaug ntawm kev sib txhuam thiab inertial tsis kam:
Ftotal>2400+4000=6400 N
4.2 Kev ntsuam xyuas ntawm qhov siab tshaj plaws ntawm 1.2 m / s:
Lub AGV accelerates ntawm 0 m / s mus rau 1.2 m / s thiab decelerates rov qab mus rau 0 m / s, nrog sib npaug acceleration thiab deceleration theem.
Cia lub sijhawm ceev tas mus li xxx vib nas this. Siv qhov sib npaug s=v0t+0.5at2s=v_0 t + 0.5at^2s=v0t+0.5at2 (nrog v0=0v_0=0v0{16}}),
peb muaj:a=2*[(8-1.2x)/2]/[(8-x)/2]²=(8-1.2x)/[(8-x)/2]²=4*(8-1.2x)/(8-x)²
Muab hais tias lub davhlau ya nyob twg ceev thaum lub sij hawm acceleration yog 1.2 m / s, qhov nruab nrab ceev yog 0.6 m / s, thiab lub acceleration (los yog deceleration) lub sij hawm yog (8−x) / 2 (8 - x) / 2 (8−x) / 2, peb kuj qhia tau hais tias:
a=0.6/[(8-x)/2]=1.2/(8-x)
Kev daws cov kev sib npaug no tau kwv yees kwv yees li:
x=56/9≈6.222,a=27/40=0.675
Qhov xav tau traction quab yuam kom kov yeej inertial kuj yog:
F=ma=8000*0.675=5400N
Yog li, qhov tsawg kawg nkaus traction quab yuam yuav tsum txaus siab:
Ftotal>2400+5400=7800 N
4.3 Rau qhov siab tshaj plaws ntawm 1.2 m / s thiab 2 m / s:
Koj tuaj yeem hloov qhov tshwj xeeb ceev qhov tseem ceeb rau hauv cov qauv saum toj no los xam cov quab yuam uas xav tau.
5. Kev Tswj Xyuas Zoo: Qhov zais cia rau kev siv hluav taws xob zoo thiab kev ua haujlwm du
Cov txheej txheem saum toj no qhia txog kev tsim qauv dav dav. Nrog rau kev tswj xyuas kom zoo dua qub, cov theem acceleration thiab deceleration tuaj yeem txheeb xyuas nyias rau kev ua haujlwm zoo.
Piv txwv li, raws li tau piav qhia, kev sib koom ua ke ntawm qhov kev sib tw ua haujlwm thaum lub sij hawm deceleration nrog lub zog rov qab traction tuaj yeem txo qhov kev xav tau rov qab, yog li txo qhov siab tshaj plaws yuav tsum tau muaj zog traction lossis ceev. Qhov no ua rau AGV tsav lub log kom ua tiav lub xeev zoo tshaj plaws uas yog ob lub zog- ua haujlwm tau zoo thiab du.
6. Cov ntsiab lus thiab kev nkag siab
Balance Ceev thiab Traction:Txij thaum P=Fv
Kev sib txuam tseem ceeb:Tus yuam sij rau kev xaiv kom zoo yog qhov sib txuam ntawm AGV tsav log txoj kab uas hla nrog qhov txo qis.
Enhanced Design thiab Algorithms:Kev txhim kho lub tsheb thiab kev ua kom zoo tshaj plaws ntawm kev tswj cov algorithms tuaj yeem txhawb kev ua haujlwm kom zoo thiab ua kom zoo, ua tiav kev txuag hluav taws xob los ntawm algorithmic refinement.
Kev sib xyaw ntawm Physics thiab Control:Tus tsim ntawm AGV tsis yog tsuas yog hais txog lub zog nyoos xwb- nws yog qhov sib xyaw ua ke zoo tshaj plaws ntawm lub cev cov ntsiab lus thiab cov kev txawj ntse tswj algorithms.
Case-Specific Analysis:Txhua qhov teeb meem yuav tsum tau txheeb xyuas kom meej raws li cov xwm txheej tshwj xeeb; tsis tsuas yog siv los yog txhais lus yuam kev ntawm qhov kev tshuaj ntsuam no raws li kev daws teeb meem thoob ntiaj teb.
