Answer
Matsakaicin madaidaicin lokacin bazara ($k$) na maɓuɓɓugan ruwa mai juyawa Crest-to-Crest an bayar da shi ta hanyar daidaitawar Timoshenko wave:
$$k = \frac{E \cdot b \cdot t^3 \cdot N_w^4}{P_m^3 \cdot N} \ lokuta K_g$$
Inda:
- $E$ shine Modulus na Matasa na Ƙarfafawa ($ N/mm^2$)
- $b$ shine kaurin bangon radial ($mm$)
- $t$ shine kaurin abu ($mm$)
- $N_w$ shine adadin raƙuman ruwa masu aiki a kowane juyi
- $P_m$ shine matsakaicin diamita na bazara ($mm$), an lissafta shi azaman $(D_{out} + D_{in}) / 2$
- $N$ shine adadin jujjuyawar aiki
- $K_g$ shine madaidaicin gyara dangane da faɗaɗa diamita yayin karkatarwa
Iyakance Ma'aunin Lissafi:
1. Juyayi da Ciwon Jiki: Tuntuɓi tsakanin igiyoyin igiyar ruwa yayin karkatarwar axial yana haifar da gogayya, wanda ke haifar da hysteresis da haɓaka ingantaccen ƙimar bazara yayin lodawa vs saukewa.
2. Iyakan karkacewa: Ma'anar ita ce madaidaiciya madaidaiciya kawai har zuwa kusan 80% na jimlar juriyar da ake samu. Bayan kashi 80%, tãguwar ruwa suna farawa ƙasa ko samar da layin layi, da haɓaka taurin bazara.
3. Shim ya ƙare: Idan an ƙayyadadden ƙarshen shim (lebur ɗin lebur) don rarraba kaya daidai gwargwado, gudummawar da suke bayarwa dole ne a lissafta ta yayin da suke haɓaka ƙaƙƙarfan tsari kuma suna rage jumillar juyi mai tasiri.
