1.Rolling arụmọrụ ule
Nzube: Iji nwalee arụmọrụ mkpọgharị nke wheel wheel mgbe ebuchara;
Ngwa ule: ihe nkedo otu wheel na-agbagharị, igwe na-anwale arụmọrụ na-eduzi;
Uzo nnwale: Dị ka egosiri na eserese 1, wụnye ihe nkedo ma ọ bụ wheel na igwe nnwale, tinye ibu nke akpọrọ W na nkedo n'akụkụ ntụzịaka plumb wee tinye ike na axle wheel na ntụzịaka kwụ ọtọ. Tụọ ike kacha nta F1 chọrọ iji tụgharịa nkedo ma ọ bụ wiilị
A na-agbakọ nguzogide ntugharị nke otu wiil dịka nha (1).
pl=F1/W…… (1)
Ebe ọnụọgụ nguzogide μ1 na-atụgharị;
F1 na-akpụ akpụ, akụkụ ahụ bụ Niu (N).
W gosiri ibu, na Nm (N).
Nke ahụ bụ: propulsion F1 = ibu W × ọnụọgụ nguzogide μ1
Nrụgharị nke otu wiil nke nkedo ga-adaba na ọkọlọtọ mba GB/T14687-2011 (Table 1).
2.Steering arụmọrụ ule
Nzube: Iji nwalee arụmọrụ steering nke eluigwe na ala casters mgbe loading;
Ngwa nnwale: igwe nlegharị anya ihe nkedo.
Ule ule: Dị ka egosiri na Fig. 2, wụnye ihe nkedo ma ọ bụ wheel na igwe ule, tinye ihe nkedo W na nkedo n'akụkụ ụzọ plumb, na tinye ike na kehoraizin direction perpendicular n'ihu n'ihu wheel. Tule ike kacha nta F2 iji duru ihe nkedo ahụ, F2 bụ nguzogide ntughari nke ihe nkedo. A na-agbakọ ọnụọgụ nke nguzogide steering dị ka nhata (1).
μ2=F2/W …… (1)
ebe μ2 bụ ọnụọgụ nke nguzogide ntugharị.
F2 Nguzogide ntugharị, na Nm; W kwadoro ibu, na Nm.
W gosiri ibu na Nm.
ntụgharị: ike ike F2 = ibu wX nguzogide ọnụọgụ μ2
Ịrụ ọrụ nrụgharị ahụ ga-agbaso ụkpụrụ GB/T14687-2011 (Table 2).
3. Nkọwa nke ụkpụrụ ule.
Ọnụ ọgụgụ nkwụsị nke ule site na 1, site na 2 dị ntakịrị, na-egosi na ntanye na-eguzogide, dị mfe iji, mgbanwe dị mma: n'ụzọ megidere nke ahụ, ọnụ ahịa dị ukwuu, nke na-eguzogide, na-arụsi ọrụ ike iji.
4. Mmekọrịta dị n'etiti ihe nkedo wheel n'elu ihe, ihe eji eme ihe na-ebugharị, ihe bọọlụ na nguzogide.
1) The ike siri ike nke caster wheel elu (dị ka PA, MC, PP, ígwè wheel, wdg), na nta nke eguzogide coefficient, mfe ọ bụ ịkwanye, ma ka njọ ọ bụ maka nchebe mmetụta nke. ala na mmetụta ogbi.
2) Mgbe elu nke wheel wheel bụ ihe dị nro (dị ka TPU, TPR, BR, wdg), ka ọnụ ọgụgụ na-eguzogide na-arịwanye elu, ka ike na-anya ụgbọ ala chọrọ, ma mmetụta dị mma nke nchebe ala na mmetụta ogbi.
3) Nke dị elu nke ike nke diski mgbokwasị ụkwụ na-ebugharị na ihe bọọlụ, na-ebelata ọnụọgụ nguzogide steering na ọ dị mfe ịkwanye.
