Dynamometer ya Brake Pad ya Galimoto - Mtundu B
Ntchito:
Buleki ndi chimodzi mwa zinthu zofunika kwambiri poyendetsa galimoto mosamala, ndipo magwiridwe ake amakhudza kwambiri chitetezo cha galimoto komanso mphamvu zake. Nthawi zambiri, magwiridwe antchito a buleki amayesedwa motsatira miyezo yoyesera yomwe imakhazikitsidwa ndi mabungwe ovomerezeka. Njira zoyesera zambiri zimaphatikizapo kuyesa zitsanzo zazing'ono ndi kuyesa benchi ya inertial. Mayeso ang'onoang'ono a zitsanzo amagwiritsidwa ntchito kutsanzira kukula ndi mawonekedwe a buleki, zomwe zimapangitsa kuti zikhale zolondola pang'ono koma mtengo wake ndi wotsika. Amagwiritsidwa ntchito kwambiri poyesa zida zokangana, kuwongolera khalidwe, komanso kupanga zinthu zatsopano.
Chida choyezera mabuleki (brake dynamometer) ndiye mayeso odalirika kwambiri pakuwunika ubwino wa mabuleki, omwe amatha kuwonetsa bwino momwe mabuleki amagwirira ntchito ndipo pang'onopang'ono akhala njira yodziwika bwino yowunikira ubwino wa mabuleki. Chimatha kuyesa machitidwe a mabuleki m'malo olamulidwa omwe amafanana ndi dziko lenileni.
Kuyesa kwa mabuleki agalimoto pogwiritsa ntchito Dynamometer ndi njira yoyesera momwe mabuleki amagwirira ntchito, yomwe imayesa momwe mabuleki amagwirira ntchito, kukhazikika kwa kutentha, kutayika kwa mawaya, ndi mphamvu ya mabuleki kudzera mu mayeso a benchi. Njira yomwe ilipo padziko lonse lapansi pano ndikuyerekeza momwe mabuleki amagwirira ntchito pogwiritsa ntchito inertia yamakina kapena inertia yamagetsi, kuti ayesere magwiridwe antchito ake osiyanasiyana. Dynamometer iyi ya split type idapangidwira kuyesa mabuleki a magalimoto apaulendo.
Ubwino:
1.1 Wolandirayo wapatulidwa ndi nsanja yoyesera kuti achepetse kugwedezeka kwa wolandirayo ndi phokoso pa mayesowo.
1.2 Chingwe choduliracho chili ndi pamwamba pa shaft yayikulu yokhala ndi mawonekedwe ozungulira, zomwe zimakhala zosavuta kusokoneza ndikugwira ntchito mokhazikika.
1.3 Benchi imagwiritsa ntchito silinda yamagetsi ya servo kuti iyendetse silinda yayikulu ya brake. Dongosololi limagwira ntchito mokhazikika komanso modalirika komanso molondola kwambiri.
1.4 Pulogalamu ya bench imatha kugwiritsa ntchito miyezo yosiyanasiyana yomwe ilipo, ndipo ndi yabwino pa ergonomic. Ogwiritsa ntchito amatha kupanga mapulogalamu oyesera okha. Dongosolo lapadera loyesa phokoso limatha kugwira ntchito palokha popanda kudalira pulogalamu yayikulu, yomwe ndi yabwino kuyang'aniridwa.
1.5 Miyezo yoyesera yotheka: AK-Master, SAE J2522, ECE R90, JASO C406, ISO 26867, GB-T34007-2017 mayeso ndi zina zotero.
