Cov ntsiab lus tseem ceeb hauv kev tsim cov tshuab hnyav undercarriage chassis

I. Core Design Requirements

1. Lub cev muaj zog thiab nruj
** Load Analysis: Nws yog ib qho tsim nyog los xam cov loads zoo li qub (cov khoom siv tus kheej qhov hnyav, lub peev xwm thauj khoom), dynamic loads (vibration, shock), thiab ua hauj lwm loads (excavation force, traction force, etc.) los xyuas kom meej tias lub chassis tsis undergo yas deformation los yog tawg nyob rau hauv huab ua hauj lwm tej yam kev mob.
** Kev xaiv cov khoom siv: Cov hlau muaj zog (xws li Q345, Q460), cov hlau tshwj xeeb, lossis cov qauv welded yuav tsum tau siv, suav nrog lub zog tensile, qaug zog, thiab kev ua haujlwm.
**Structural Optimization: Txheeb xyuas qhov kev faib tawm ntawm kev ntxhov siab los ntawm finite element tsom xam (FEA), thiab txais yuav lub thawv girders, I-beams, los yog truss qauv los txhim kho khoov / torsional nruj.

2. Kev ruaj ntseg thiab sib npaug
** Lub Chaw Tswj Lub Nkoj: Tsim nyog faib qhov chaw nruab nrab ntawm lub ntiajteb txawj nqus ntawm cov khoom siv (xws li txo qis lub cav, tsim cov khoom hnyav), kom tsis txhob muaj kev pheej hmoo ntawm kev tig.
** Khiav thiab Wheelbase: Kho qhov khiav thiab lub log raws li qhov chaw ua haujlwm (qhov tsis sib xws lossis hauv av tiaj tus) txhawm rau txhim kho lateral / longitudinal stability.
** Suspension System: Tsim hydraulic ncua kev kawm ntawv, huab cua-roj springs los yog roj hmab shock absorbers raws li cov yam ntxwv ntawm kev co ntawm cov tshuab hnyav los txo qhov cuam tshuam dynamic.

3. Durability thiab Service Life
** Fatigue-resistant Design: Kev ntsuam xyuas lub neej qaug zog yuav tsum tau ua ntawm qhov tseem ceeb (xws li cov ntsiab lus pob khawm thiab vuam seams) kom tsis txhob muaj kev ntxhov siab.
** Kev kho tiv thaiv corrosion: Siv kub-dip galvanizing, epoxy resin txau, lossis cov txheej txheem sib xyaw kom haum rau qhov chaw hnyav xws li noo noo thiab ntsev tsuag.
** Kev Tiv Thaiv Hnav-Resistant: Txhim kho hnav-resistant steel daim hlau los yog cov ntaub ntawv hloov tau hauv cov cheeb tsam uas nyiam hnav (xws li cov kab txuas thiab cov phaj hauv qab).

4. Powertrain Matching
**Powertrain Layout: Qhov kev npaj ntawm lub cav, kis tau tus mob, thiab tsav qag yuav tsum xyuas kom meej lub hwj chim kis tau tus mob txoj kev kom txo tau lub zog poob.
**Kev Siv Hluav Taws Xob: Ua kom zoo dua qhov sib piv ntawm cov gearboxes, hydraulic motors, lossis hydrostatic drives (HST) kom ntseeg tau tias kev sib kis tau zoo.
** Kev Tsim Kho Thaum Tshav Kub Kub: Khaws cov cua kub tawm los yog sib xyaw ua ke kom txias kom tsis txhob muaj cua sov ntau dhau ntawm cov khoom sib kis.

II. Environmental Adaptability Requirements
1. Terrain Adaptability
** Kev Xaiv Mechanism: Taug qab-hom chassis (kev sib cuag hauv av siab, haum rau hauv av mos) lossis lub log-hom chassis (kev kub ceev, hauv av nyuaj).
** Av Clearance: Tsim kom muaj av clearance raws li qhov yuav tsum tau rau passability kom tsis txhob lub chassis scraping tiv thaiv obstacles.
** Steering System: Cov kauj tsheb sib txuas, lub kauj tsheb kauj vab lossis cov kauj vab sib txawv kom ntseeg tau tias muaj kev sib tw hauv thaj chaw nyuaj.

2. Kev ua haujlwm siab heev teb
** Kub Adaptability: Cov ntaub ntawv yuav tsum muaj peev xwm ua hauj lwm nyob rau hauv thaj tsam ntawm -40 ° C mus rau +50 ° C los tiv thaiv nkig tawg nyob rau hauv qis kub los yog creep ntawm high kub.
** Plua plav thiab dej tsis kam: Cov khoom tseem ceeb (cov kabmob, cov ntsaws ruaj ruaj) yuav tsum tau tiv thaiv nrog qhov ntsuas IP67 lossis siab dua. Cov khoom tseem ceeb kuj tseem tuaj yeem muab ntim rau hauv lub thawv kom tiv thaiv kev nkag ntawm cov xuab zeb thiab av.

III. Kev ruaj ntseg thiab kev cai yuav tsum tau
1. Tsim kev nyab xeeb
** Roll-over Protection: Nruab nrog ROPS (Roll-over Protective Structure) thiab FOPS (Kev Tiv Thaiv Caij Nplooj Hlav).
** Emergency Braking System: Redundant braking design (mechanical + hydraulic braking) kom paub meej cov lus teb ceev ceev thaum muaj xwm txheej ceev.
** Kev Tiv Thaiv Kev Tiv Thaiv Kev Txhaum Cai: Ntawm txoj kev ntub dej los yog kev nplua los yog qhov chaw siab tshaj, kev sib tw yog txhim kho los ntawm kev sib txawv ntawm cov xauv los yog hluav taws xob los tiv thaiv kev ua haujlwm.

2. Kev ua raws cai
**International Standards: Ua raws li cov qauv xws li ISO 3471 (ROPS xeem) thiab ISO 3449 (FOPS xeem).
** Ib puag ncig yuav tsum tau muaj: Ua tau raws li cov qauv emission (xws li Tier 4 / Theem V rau cov tshuab tsis-txoj kev) thiab txo cov suab nrov.

IV. Kev tu thiab kho
1. Modular Tsim: Cov khoom tseem ceeb (xws li tsav axles thiab hydraulic pipelines) yog tsim los rau hauv cov qauv qauv kom ceev disassembly thiab hloov.
2. Kev Kho Kom Yooj Yim: Kev tshuaj xyuas qhov yog muab thiab cov ntsiab lus lubrication yog qhov nruab nrab ntawm kev tswj xyuas lub sijhawm thiab cov nqi.
3. Kev Ntsuas Kev Ntsuas: Kev sib xyaw sensors saib xyuas qhov tsis xws li roj siab, qhov kub thiab txias, thiab kev vibration, txhawb cov chaw taws teeb ceeb toom ntxov lossis OBD systems.

V. Lub teeb yuag thiab lub zog muaj zog
1. Cov Khoom Siv Qhov hnyav: Siv cov hlau muaj zog, aluminium alloys, lossis cov ntaub ntawv sib xyaw thaum ua kom muaj kev ncaj ncees.
2. Topology Optimization: Siv CAE thev naus laus zis los tshem tawm cov khoom siv tsis tu ncua thiab ua kom zoo dua cov ntaub ntawv (xws li hollow beams thiab honeycomb structures).
3. Kev Tswj Kev Siv Hluav Taws Xob: Txhim kho qhov kev ua haujlwm ntawm kev sib kis tau zoo kom txo tau roj lossis hluav taws xob noj.

VI. Customized Tsim
1. Cov qauv kev sib txuas nruab nrab: Txhim kho cov qauv zoo raws li lub peev xwm thauj khoom thiab kev sib txuas ntawm cov khoom siv sab saud, suav nrog kab teeb, platforms, kab, thiab lwm yam.
2. Lifting lug tsim: Tsim lifting lugs raws li qhov yuav tsum tau nqa ntawm cov khoom siv.
3. Logo tsim: Sau lossis kos lub logo raws li tus neeg siv khoom xav tau.
