Los tiv thaiv -loosing tsim thiab daim ntawv thov ntawm elastic rail clips
Dab tsi yog qhov kev tiv thaiv zoo tshaj -loosing tsim rau elastic rail clips?
Cov kev tiv thaiv ntau tshaj -loosing txoj kev suav nrog kev sib txuam xauv cov txiv ntseej, uas ua rau kom muaj kev sib txhuam los ntawm cov xov xov tshwj xeeb. Ib co elastic clips siv elastic washers rau pab tiv thaiv -loosing, tswj preload los ntawm elastic deformation ntawm lub washers. Cov qauv tsim ntawm elastic clip nws tus kheej yog optimized, xws li nce lub caij nplooj ntoos hlav stroke thiab elastic rov qab quab yuam kom txo loosening los ntawm kev co. Xov gluing thev naus laus zis yog siv los txhim kho cov adhesion ntawm cov xov los ntawm cov nplaum. Lwm tus txhim kho qhov qaug zog tiv thaiv ntawm cov khoom siv elastic kom tsis txhob muaj qhov elasticity thiab loosening nyob rau hauv lub sij hawm ntev - vibration.
Yuav ua li cas elastic clips tiv thaiv -loosening nyhuv nyob rau hauv siab - zaus vibration ib puag ncig?
Nyob rau hauv siab -ntau zaus vibration ib puag ncig, elastic clips yuav tsum tau siv cov ntaub ntawv nrog siab elastic modulus, xws li siab- zoo caij nplooj ntoos hlav steel, kom zoo elastic rov qab muaj peev xwm. Cov txiv ntoo xauv yog siv nrog elastic clips, thiab lawv cov qauv xauv tuaj yeem tiv taus qhov cuam tshuam los ntawm kev co. Lub installation preload ntawm elastic clips yuav tsum nruj me ntsis tswj kom muaj zog clamping txaus los tiv thaiv qhov cuam tshuam ntawm kev co. Kev saib xyuas tsis tu ncua thiab kev tshuaj xyuas yog nqa tawm kom lub sijhawm ua kom xoob xoob xoob xoob xoob xoob xoob xoob xoob xoob xoob xoob xoob xoob xoob xoob xoob xoob xoob xoob xoob xoob xoob xoob xoob xoob xoob xoob xoob uas tau hais los saum toj saud thiab khaws cov kev tiv thaiv kev tiv thaiv -loosing nyhuv. Hauv qee qhov xwm txheej, ob lub txiv ntoo xauv cov qauv raug saws los txhim kho kev tiv thaiv -loosing kev cia siab.
Dab tsi yog qhov txawv ntawm kev tiv thaiv -loosing yuav tsum tau ntawm elastic clips rau lub nroog rail transit thiab railway kab tseem ceeb?
Kev tsheb ciav hlau hauv nroog tsheb ciav hlau ua haujlwm nquag nquag pib thiab nres, yog li kev tiv thaiv -loosing xav tau rau elastic clips tsom ntau dua rau kev ua haujlwm ntev hauv siab - zaus vibration. Cov kab tsheb ciav hlau tseem ceeb ntawm cov tsheb ciav hlau muaj cov khoom loj, yog li kev tiv thaiv - loosening ntawm elastic clips yuav tsum xub xyuas kom txaus clamping quab yuam los tiv thaiv hnyav load. Elastic clips rau kev tsheb ciav hlau hauv nroog feem ntau tau txais kev sib xyaw ua ke los tiv thaiv -loosing designs, xws li xauv txiv ntseej + elastic washers, thaum txoj kev tsheb ciav hlau tseem ceeb yuav siv tau yooj yim tab sis siab - lub zog tiv thaiv -loosing qauv. Txoj kev tiv thaiv -loosing txij nkawm lub voj voog ntawm elastic clips rau kev tsheb ciav hlau hauv nroog yog luv dua, thaum txoj kev tsheb ciav hlau tseem ceeb yuav tsum sib npaug ntawm kev ua haujlwm ntev thiab kev saib xyuas yooj yim. Txoj kev tiv thaiv -loosing test standard for the two is also different, with urban rail transit focusing more on simulating high-frequency start-stop working condition.
Dab tsi cuam tshuam rau qhov qis- qhov kub thiab txias ib puag ncig muaj rau kev tiv thaiv-loosing kev ua tau zoo ntawm elastic clips thiab yuav ua li cas nrog nws?
Qhov ntsuas kub qis yuav txo qhov tawv ntawm cov khoom siv elastic, uas tuaj yeem ua rau txo qis elastic rov qab quab yuam thiab cuam tshuam rau kev tiv thaiv -loosing nyhuv. Kev sib txhuam ntawm cov xov yuav hloov ntawm qhov kub thiab txias, ua rau muaj kev pheej hmoo ntawm xoob. Txhawm rau daws qhov no, qis-cov ntaub ntawv kub resistant elastic clip yuav tsum raug xaiv kom ruaj khov elastic ua haujlwm ntawm qhov kub thiab txias. Xauv txiv ntseej nrog lub zog qis-kub adaptability yog siv kom tsis txhob qis- kub embrittlement. Lub preload yog tsim nyog nce thaum lub sij hawm installation los them rau kev ua tau zoo attenuation ntawm qis kub. Kev tshuaj xyuas tsis tu ncua yog ua nyob rau hauv qis- lub caij kub kub kom raws sij hawm tuav cov elastic clips thiab xyuas kom muaj kev tiv thaiv- xoob kev ntseeg tau.
Dab tsi yog cov kev sim rau kev tiv thaiv -loosing kev ua tau zoo ntawm elastic clips?
Ib qho kev sib tw vibration table simulation yog siv los simulate siab - zaus vibration thaum lub tsheb ciav hlau ua haujlwm thiab kuaj xyuas qhov loosening ntawm elastic clips. Kev sim ua lub neej qaug zog yog ua los xyuas qhov kev tiv thaiv -loosing nyhuv tom qab ntev- siv los ntawm kev rov ua dua kev co. Lub preload attenuation ntawm elastic clips yog ntsuas los ntsuas qhov stability ntawm anti-loosing kev ua tau zoo. Kev ntsuas siab siab - qhov ntsuas kub qis yog ua los tshuaj xyuas qhov kev tiv thaiv - loosening kev cia siab nyob rau hauv ib puag ncig kub sib txawv. Los ntawm txoj kev sim ua haujlwm tiag tiag, kev tiv thaiv -loo kev ua tau zoo ntawm elastic clips nyob rau hauv kev ua haujlwm tiag tiag raug soj ntsuam kom ntseeg tau tias lawv ua tau raws li qhov yuav tsum tau siv.
