Kana mainjiniya nemametrologist vakasarudza chaiyo granite chikuva chekuyera kuyerwa uye mabasa egungano, sarudzo yekupedzisira inowanzo tarisa pane inoita seiri nyore parameter: ukobvu hwayo. Asi, ukobvu hwegranite pamusoro peplate yakanyanya kupfuura chiyero chakareruka-ndicho chinhu chekutanga chinoraira huwandu hwayo hwekuremerwa, kuzunguzika kuramba, uye pakupedzisira, kugona kwayo kuchengetedza kwenguva yakareba dimensional kugadzikana.
Pakushandisa kwepamusoro-soro, ukobvu hahusarudzwe zvisina tsarukano; iko kukosha kweinjiniya kuverenga kwakavakirwa pamatanho akatarwa uye misimboti yakaoma yekumisikidza mechanic.
Iyo Injiniya Mwero Kuseri Kwehukobvu Kutsunga
Chinangwa chekutanga chepuratifomu chaiyo ndechekushanda seyakanyatso furatirwa, isingazungunuke referensi ndege. Naizvozvo, ukobvu hwegranite pamusoro peplate inonyanya kuverengerwa kuti ive nechokwadi chekuti pasi pehukuru hwayo hunotarisirwa, kuwanda kweplateti kunoramba kuri mukati megiredhi rayo rekushivirira (semuenzaniso, Giredhi AA, A, kana B).
Iyi dhizaini yekugadzira inotevedzera inotungamira indasitiri nhungamiro, senge ASME B89.3.7 chiyero. Nheyo yakakosha mukutsunga ukobvu kudzikisa kutsauka kana kukotama. Isu tinoverenga ukobvu hunodiwa nekutarisa zvivakwa zvegranite-kunyanya yayo Young's Modulus yeElasticity (chiyero chekuomarara) -pamwe chete nendiro zviyero zvese uye mutoro unotarisirwa.
The Authority Standard for Load Capacity
Iyo inogamuchirwa zvakanyanya ASME yakajairwa inobatanidza ukobvu zvakananga kune iyo ndiro inotakura-kutakura simba uchishandisa chaiyo yekuchengetedza margin:
Mutemo Wekugadzikana: Iyo granite chikuva chinofanirwa kuve chakakora zvakakwana kuti chitsigire iyo yese yakajairika mutoro wakaiswa pakati peplate, pasina kutenderedza ndiro pamwe nechero diagonal neinopfuura hafu yekushivirira kwayo kwese kushivirira.
Ichi chinodiwa chinoita kuti ukobvu hunopa iyo inodiwa kuomarara kutora huremu hwakaiswa uchichengetedza sub-micron kurongeka. Papuratifomu yakakura kana yakawandisa, ukobvu hunodiwa hunowedzera zvakanyanya kupikisa nguva yekukotama yakawedzera.
Ukobvu: The Triple Factor in Precision Stability
Ukobvu hwepuratifomu hunoita semugadziriso wakananga wekusimba kwayo kwechimiro. Ndiro yakakora inopa matatu makuru, akabatana mabhenefiti akakosha kune chaiyo metrology:
1. Kuwedzeredzwa Kwemutoro uye Kuchengeta Flatness
Hukobvu hwakakosha pakuramba nguva yekukotama inokonzerwa nezvinhu zvinorema, senge mahombe ekuyeresa emuchina (CMMs) kana zvinhu zvinorema. Kusarudza hukobvu hunodarika hudiki hunodiwa hunopa kukosha kwekuchengetedza margin. Izvi zvekuwedzera zvinhu zvinopa chikuva chinodiwa misa uye chimiro chemukati kuti chigovane mutoro zvinobudirira, nokudaro zvichideredza zvakanyanya kutsauka kweplate uye kuve nechokwadi kuti inodiwa yepasi flatness inochengetedzwa pamusoro pehupenyu hwese hwepuratifomu.
2. Kuwedzera Dynamic Kugadzikana uye Vibration Damping
Iyo gobvu, inorema giraniti slab ine hukuru hukuru, iyo yakakosha pakunyorovesa mechanic uye acoustic ruzha. Ipuratifomu hombe ine yakaderera yakasarudzika frequency, ichiita kuti isanyanya kubatwa nekudengenyeka kwekunze uye seismic chiitiko chinowanikwa munzvimbo dzemaindasitiri. Uku kunyorova kwepasi kwakakosha kune yakakwirira-resolution optical inspection uye laser alignment masisitimu uko kunyangwe kufamba kusinganzwisisike kunogona kukanganisa maitiro.
3. Kugadzirisa Thermal Inertia
Iyo yakawedzera vhoriyamu yezvinhu inoderedza kuderera kwekushisa. Nepo giraniti yemhando yepamusoro yatove ichizvikudza yakaderera coefficient yekuwedzera kwemafuta, ukobvu hukuru hunopa yepamusoro yekupisa inertia. Izvi zvinodzivirira kukurumidza, kusina-uniform thermal deformation inogona kuitika kana michina ichipisa kana kutenderera kwemhepo, kuve nechokwadi chekuti geometry yepuratifomu inoramba ichienderana uye yakagadzikana kwenguva refu yekushanda.
Munyika yeinjiniya chaiyo, ukobvu hwepuratifomu yegranite hachisi chinhu chekudzikisira mari yekuchengetedza, asi chinhu chekutanga chekugadzirisa, kuve nechokwadi chekuti setup yako inopa inodzokororwa uye inoteedzera mhedzisiro inodiwa nekugadzirwa kwemazuva ano.
