Rim loads yuav categorized li
Static load: Lub zog xa mus rau lub log rim ntawm lub kaw lus ncua kev kawm thaum lub tsheb nyob ruaj ruaj, tshwm sim los ntawm lub tsheb qhov hnyav.
Dynamic load: Lub zog dynamic ntxiv rau ntawm lub log vim yog inertial thiab cuam tshuam quab yuam thaum lub tsheb nyob rau hauv kev txav, cornering, braking, los yog traversing uneven nto. Dynamic loads feem ntau loj dua li cov khoom qub.
Qhov tseem ceeb ntawm Rim Loads
Kev nyab xeeb: Rims yuav tsum muaj lub zog txaus thiab rigidity los tiv thaiv cov khoom no, tiv thaiv kev tawg lossis deformation thaum ua haujlwm. Qhov no yog qhov tseem ceeb tshaj plaws uas yuav tsum tau muaj kev nyab xeeb.
Tsim Kev Tsim Nyog: Ua haujlwm raws li lub hauv paus tseem ceeb rau kev tsim qauv thiab xaiv cov khoom siv ntawm cov rims (tshwj xeeb yog cov khoom tseem ceeb xws li spokes, rim grooves, thiab flanges).
Fatigue Life: Cyclic rim loads yog thawj qhov ua rau hlau qaug zog hauv rims. Kev tsim qauv yuav tsum suav txog qhov muaj kev nyab xeeb nyob rau hauv qhov siab tshaj plaws loads thiab xyuas kom ntev - lub sij hawm qaug zog endurance.
Lub peev xwm thauj khoom ntawm lub log rim tsis yog arbitrarily sau npe; nws yog tus nqi thauj khoom muaj kev nyab xeeb suav thiab ntsuas cov kauj ruam los ntawm cov tuam txhab muaj npe nrov los ntawm cov qauv + tsim + cov ntaub ntawv + cov txheej txheem tsim khoom + kev sim tiag tiag, thiab tau teev nyob rau hauv cov khoom specifications.
Tsis tas li ntawd, cov khoom siv sib txawv (forklifts, trailers, kev tsim kho tshuab) txhua tus ua raws li cov qauv tsim thiab cov qauv thauj khoom. Yog li ntawd, thaum hloov rims, nws yog ib qho tseem ceeb kom ntseeg tau tias lub peev xwm load peev xwm ntawm lub rim tshiab tau ntsib los yog tshaj qhov qub chaw tsim khoom tshwj xeeb.
Lub nra hnyav sawv cev rau qhov sib sau ntawm tag nrho cov quab yuam uas lub ntug yuav tsum tiv taus thoob plaws hauv lub tsheb tag nrho cov kev pab cuam lub neej, uas yog ib qho tseem ceeb ntawm kev ua tau zoo rau kev ua kom lub ntug kev nyab xeeb thiab txhim khu kev qha.
