Ongororo Yekutsigira Zvivakwa zveMattress Materials

Munyori: Synwin– Custom Metiresi

Mamiriro ekubatana pakati pematiresi nemuviri wemunhu achakanganisa kunyaradzwa kunoonekwa kwemuviri wemunhu uye kunowedzera kukanganisa kunaka kwekurara. Zvinowanzova chikonzero chakananga chekumanikidzwa kwemaronda kune varwere vanogara kwenguva refu pamubhedha. Muna 1998, Peter naAvalino [1] vakadzidza mattresses vachishandisa bvunzo yekumanikidza kwemuviri wemunhu uye subjective evaluation yekunyaradza, uye mhedzisiro yakaratidza kuti mattresses akaedzwa aive nekunyaradza kuri nani pane incompressible puranga. Muna 1988, Shelton [2] akakurudzira indekisi yekumanikidza (Pindex) kuburikidza nenhamba huru yekuongorora data paunenge uchigadzira avhareji yekumanikidza pakati, peak yekumanikidza, kumanikidza peak magnitude nezvimwe zvinhu, uye akaienzanisa nemetiresi decompression test effect, ichiratidza kuita kwakanaka kwazvo. kuwirirana kwakanaka.

Muna 2000, Defloor [3] yakaita ongororo pamusoro pesimba renzvimbo dzakasiyana dzekurara pamhepo yematiresi. Chidzidzo chacho chakaratidza kuti 30 ° semi-sitting position uye nzvimbo yakarerekera yaive nedikita diki pane metiresi yekubata kumeso, ukuwo 90 ° divi rakarara nzvimbo yaive nedzvinyiriro yakaderera pametiresi. Iyo yakakura, iyo yakawanikwa zvakare kushandisa yakajairwa furo metiresi, yakaderedzwa interface kudzvanywa ne20 kusvika 30 muzana. Muna 2000, Bader [4] akaita chidzidzo pamusoro pehukama huri pakati pehutano hwekurara uye kuoma kwepamubhedha, uye akawana kuti vanhu vakawanda vaikwanisa kujairana nemetiresi yakapfava kupfuura metiresi yakasimba. Muna 2010, Jacobson et al. [5] yakaita chidzidzo kune varwere vane kurwadziwa kwakadzika shure kana kuoma. Chidzidzo ichi chakawana kuti kubata kwemuviri wemunhu panguva yekurara kune kukanganisa pamhando yekurara. Kutsiva metiresi iri pakati nepakati kunogona kugadzirisa kusagadzikana kwekurara uye kurerutsa chiuno chemurwere. Kurwadza kwemusana uye kuoma.

Mumakore achangopfuura, nyanzvi dzeChinese dzakawedzerawo tsvakiridzo yadzo pamamatiresi, uye muviri mukuru uchiri kuratidzwa muhukama pakati pekunyaradza kwematiresi, kunaka kwekurara, ukobvu hwemetiresi, uye zvinhu zvenyama. Muna 2009, Li Li et al. [6-7] akayera body pressure distribution distribution index yemuviri wemunhu nekushandura ukobvu hwesponji pamusoro pematiresi, ndokuita comprehensive subjective and objective analysis, ndokuona kuti ukobvu hwesponji hunoita zvakakosha pakunyaradza kwematiresi. Muna 2010, marudzi akasiyana emamatiresi esponji akasarudzwa, uye kukanganisa kwemhando dzeponji pakunyaradza kwese uye kwenzvimbo kwemuviri wemunhu kwakaongororwa nekuenzaniswa.

Muna 2014, apo Hou Jianjun [8] akadzidza pesvedzero yemidziyo yematiresi pahunhu hwemuviri wemunhu munzvimbo yekumusoro, akaona kuti nzvimbo yekubatana pakati pematiresi nemuviri wemunhu yakakura, uye kubata kwenguva refu kunogona kutungamirira nyore kuneta kwevanhu. Zvinogona kuoneka kubva pamusoro apa kuti tsvakiridzo pamamatiresi inonyanya kurerekera muyedzo yekumanikidza kugovera, uye zvakare inogumira kune zvimwe zvinhu. Chinangwa chekuongorora nzira dzerutsigiro rwezvinhu zvematiresi hazviwanzo.

Mubepa rino, 6 akajairwa matiresi zvinhu zvinosarudzwa, uye bvunzo yekumanikidza munzira ukobvu uye bvunzo yekumanikidza yemuviri wemunhu inoitwa pavari. Iyo inotsigira mhedzisiro yematiresi zvinhu. 1 Nzira yekuedza Mudzidzi wepakoreji wechikadzi ane hutano akasarudzwa bvunzo. Nyaya yacho yakanga isina nhoroondo yechirwere chemusculoskeletal, yaiva nemakore makumi maviri nemana, yakanga yakareba 165 cm, uye yairema 55 kg. Zvishandiso zvakasarudzwa muchiyedzo ichi zvakajairwa chipanje, furo rekurangarira, siponji yakatwasuka, mbiri dzakasiyana density yepfapfaidzo furo uye 3D zvinhu. Iko kudzvanya kuita kwemetiresi zvinhu kwakaedzwa uchishandisa American Instron-3365 zvinhu zvekuyedza muchina, uyo unonyanya kushandiswa kunetsa kwezvinhu. Elongation test.

Kuti uedze zvimiro zvemattress zvinhu, peya yeakanyatsogadzirwa 10cm × 10cm sikweya mahwendefa akasungirirwa kune ekumusoro neazasi chucks zvakateerana kuti aone iyo compression test. Iyo metiresi zvinhu inochekwa kuita silinda ine dhayamita ye6.6mm, inoiswa pazasi bvunzo ndiro, yekumusoro simbi ndiro inodzvanya zvishoma nezvishoma iyo metiresi zvinhu zvichidzika, uye inomisa kudzvanya kana ukobvu hwasvika 5mm, uye inonyora kudzvanywa kubva pakutanga kwekumanikidza kusvika kumagumo ekuedza. . Muyedzo wekugovera kudzvanywa kwemuviri unotora iyo yekupfeka nyaradzo yekuyedza system yeJapan AMI Kambani.

Chishandiso chinoshandisa chibharumu-mhando yekumanikidza sensor, iyo inounganidza data yega 0.1s panguva yekuedzwa. Nokuda kwekuedzwa kwekuparadzirwa kwemuviri, zvikamu zve6 zvechinomwe chepervical vertebra, pfudzi, musana, gumbo, chidya nemhuru zvakasarudzwa kuti zviongororwe, uye ma sensors e airbag ane dhayamita ye20 mm akabatanidzwa kune imwe neimwe yekuedzwa. Iyo tester inorara yakatsetseka pamatiresi, uye kana iyo yekumanikidza data yakagadzikana, iyo data inorekodhwa kwemaminetsi maviri.
