Du beh\u00f8ver ikke at v\u00e6re matematikekspert for at bruge vores belastningsberegner<\/a>.
Denne guide hj\u00e6lper dig med at komme i gang, s\u00e5 du kan beregne, hvilke dimensioner du skal bruge til dit projekt.<\/strong><\/p>\n\n\n\n

<\/p>\n\n\n\n

\n\n\n\n

NB: Bem\u00e6rk venligst, at resultatet af styrkeberegningen kun g\u00e6lder for den valgte profil. Ved dimensionering af konstruktioner med forskellige profiler skal styrkeberegningen udf\u00f8res for hele konstruktionen.<\/strong><\/p>\n<\/div><\/div>\n\n\n\n

Tr\u00e6f gode valg til dit projekt<\/strong><\/h3>\n\n\n\n

Vores belastningsberegner er designet til at give dig de oplysninger, du har brug for, for at tr\u00e6ffe et godt valg, n\u00e5r det kommer til dimensionering af dit projekt.<\/p>\n\n\n\n

Beregneren giver dig mulighed for at teste alle vores strukturelle profiler i en r\u00e6kke forskellige brugsscenarier.<\/p>\n\n\n\n

Du v\u00e6lger profildimensionerne og de belastningsforhold, du vil tage h\u00f8jde for.<\/p>\n\n\n\n

Forst\u00e5else af belastningsberegneren<\/strong><\/h3>\n\n\n\n

1. Profilvalg<\/strong>
Her v\u00e6lger du den type profil, du vil analysere.<\/p>\n\n\n\n

2. Dimension<\/strong>
Her v\u00e6lger du dimensionerne for den valgte profiltype. Dimensioner er angivet i mm som H-h\u00f8jde, B-bredde og T-tykkelse. I menuen er vores tilg\u00e6ngelige og lagerf\u00f8rte profiler listet.<\/p>\n\n\n\n

3. E-modul (MPa)<\/strong>
E-modul (MPa) er den elasticitetsenhed, der beskriver profilens stivhed. For vores glasfiberprofiler vil stivheden v\u00e6re 24000 MPa.<\/p>\n\n\n\n

4. Indl\u00e6s profil<\/strong>
Her v\u00e6lger du, hvordan belastningen skal fordeles p\u00e5 profilen. F\u00f8lgende muligheder:<\/p>\n\n\n\n

    \n
  • Belastningstilf\u00e6lde 1 \u2013 last p\u00e5f\u00f8rt i Newton (N), som en koncentreret last midt p\u00e5 profilen fastsp\u00e6ndt i begge ender.<\/li>\n\n\n\n
  • Belastningstilf\u00e6lde 2 \u2013 last p\u00e5f\u00f8rt j\u00e6vnt fordelt over hele profilen i Newton pr. meter (N\/m) p\u00e5 profil sp\u00e6ndt i begge ender.<\/li>\n\n\n\n
  • Belastningstilf\u00e6lde 3 \u2013 last p\u00e5f\u00f8rt i Newton (N), som koncentreret last ved enden af profilen sp\u00e6ndt i den modsatte ende.<\/li>\n\n\n\n
  • Belastningstilf\u00e6lde 4 \u2013 last p\u00e5f\u00f8rt j\u00e6vnt fordelt over hele profilen i Newton pr. meter (N\/m) p\u00e5 en profil, der er sp\u00e6ndt i den ene ende.<\/li>\n<\/ul>\n\n\n\n

    5. Densitet (g\/cm3)
    <\/strong>Densitet (g\/cm\u00b3) er materialets densitet, v\u00e6gt pr. volumen. Denne v\u00e6rdi er forudfyldt med 1,8 g\/cm\u00b3 (1800 kg\/m\u00b3), hvilket g\u00e6lder for profiler produceret ved at tr\u00e6kke profilen gennem et formv\u00e6rkt\u00f8j (pultrudering).<\/p>\n\n\n\n

    6. L\u00e6ngde (m)<\/strong>
    Her indtastes den profill\u00e6ngde, der uds\u00e6ttes for last. For lasttilf\u00e6lde 1 og 2 anvendes l\u00e6ngden mellem fastg\u00f8relsespunkter \/ underst\u00f8tning. For lasttilf\u00e6lde 3 og 4 anvendes den udragende l\u00e6ngde.<\/p>\n\n\n\n

    7. Distribueret last (N\/m) \/ Punktlast (N)
    <\/strong>Her angives den belastning, som profilet uds\u00e6ttes for. Ved j\u00e6vnt fordelt belastning angives belastningen i N\/m (eksempel 3.000 N\/m = 3KN\/m = ca. 300 kg\/m). Ved koncentreret belastning angives belastningen i N (eksempel 3.000 N = 3KN = ca. 300 kg).<\/p>\n\n\n\n

    Resultater<\/strong>
    De forskellige resultater vil \u00e6ndre sig i realtid baseret p\u00e5 de betingelser, du har defineret ovenfor. Resultaterne giver dig et klart overblik over, hvordan profilen opf\u00f8rer sig under belastning, s\u00e5 du kan vurdere, om den opfylder kravene i dit projekt.<\/p>\n\n\n\n

    Nedenfor finder du en forklaring af alle de resultater, du f\u00e5r pr\u00e6senteret.<\/p>\n\n\n\n

    Maks. nedb\u00f8jning (mm)
    <\/strong>Beregnet nedb\u00f8jning i mm for profilen (maksimal v\u00e6rdi). Nedb\u00f8jningen b\u00f8r ikke overstige 1:200 af den belastede profill\u00e6ngde. Eksempel: Med en belastet profill\u00e6ngde p\u00e5 4.000 mm (4 m) b\u00f8r nedb\u00f8jningen ikke overstige 20 mm. <\/p>\n\n\n\n

    Maks. b\u00f8jningssp\u00e6nding (MPa)
    <\/strong>B\u00f8jningssp\u00e6nding for profil i Megapascal (MPa) som maksimal v\u00e6rdi.<\/p>\n\n\n\n

    B (mm3)
    <\/strong>Sektionsmodul, som beskriver profilens modstand mod b\u00f8jning.<\/p>\n\n\n\n

    Masse (kg)
    <\/strong>Profilv\u00e6gt angivet i kilogram.<\/p>\n\n\n\n

    Maks. b\u00f8jningsmoment (Nm)
    <\/strong>B\u00f8jningsmoment for profilen i nanometer (maksimal v\u00e6rdi).<\/p>\n\n\n\n

    Forl\u00e6ngelse (%)
    <\/strong>Profilforl\u00e6ngelse under belastning i procent.<\/p>\n\n\n\n

    I (<\/strong>mm\u2074)
    <\/strong>Inertimomentet, som beskriver profilets stivhed ved b\u00f8jning.<\/p>\n\n\n\n

    Areal (mm2)
    <\/strong>Profilens tv\u00e6rsnitsareal, arealet af den faktiske snitflade, n\u00e5r profilen er sk\u00e5ret p\u00e5 tv\u00e6rs.<\/p>\n\n\n\n

    Eksempel<\/strong><\/h4>\n\n\n\n

    Kan en 150 mm H-bj\u00e6lke, afstivet i begge ender, med et \u00e5bent sp\u00e6ndvidde p\u00e5 4 m klare en last p\u00e5 300 kg\/m (total last p\u00e5 4 m = 1,2 tons)?<\/p>\n\n\n\n

    Fra beregneren skal du v\u00e6lge H-profil \u2013 under Dimensioner skal du v\u00e6lge H-bj\u00e6lke med H-152 mm, B-152 mm, T-6,4 mm. Fra Lastprofil skal du v\u00e6lge Lasttilf\u00e6lde 2 \u2013 j\u00e6vnt fordelt last.<\/p>\n\n\n\n

    Under L\u00e6ngde (m) skal du indtaste 4 m, og under Fordelt belastning skal du indtaste 3000 N\/m (300 kg (kp) = 2943 N).<\/p>\n\n\n\n

    Beregnet nedb\u00f8jning: 7 mm<\/p>\n\n\n\n

    Den anbefalede maksimale nedb\u00f8jning er 1:200, hvilket for et \u00e5bent sp\u00e6nd p\u00e5 4 m giver en maksimal tilladt nedb\u00f8jning p\u00e5 20 mm.<\/p>\n\n\n\n

    Konklusion:<\/strong> Beregnet nedb\u00f8jning er 7 mm. Anbefalet maksimal nedb\u00f8jning er 20 mm. 150 mm H-bj\u00e6lken kan bruges til en belastning p\u00e5 300 kg\/m.<\/p>","protected":false},"featured_media":1991,"template":"","meta":{"_acf_changed":false},"categories":[],"class_list":["post-1442","fagartikler","type-fagartikler","status-publish","has-post-thumbnail","hentry"],"acf":[],"yoast_head":"\nHvordan bruke v\u00e5r lastkalkulator -
