Tezlanish grafigini (5-rasm) chizish uchun tezlik grafigini yuqoridagi tartibda differentsiallaymiz. Tezlanish grafigining masshtabini tanlaymiz.


Kerakli asbob va moslamalar
Tekis mexanizmlarning modellari nabori (TMM5M tipidagi), o`lchov asboblari, chizmalar yig’imi.
Tajribani bajarilish tartibi.
1. Tadkik kiluvchi (izlanuvchi) model tanlang va kiruvchi bo`g’in xarakat konunini aniklang. Mexanizm bo`g’inlarini o`lchang va mexanizmni masshtab bo`yicha kinematik sxemasini tuzing. Krivoship aylanasini teng 12 bo`lakka bo`ling, aylanadagi nolinchi nuktani eng chetki xolatiga mos keluvchi vaziyatni kabul kiling. Mexanizmni 12 xolatini ko`ring.
2. Mexanizm bo`g’inlarining biror bir nuktasini xarakat traektoriyasini kabul kilib ma`lum masshtabda yo`l diagrammasini ko`ring.
3. Tezlik va tezlanish masshtabini xisoblang va grafik differentsiallash usulidan foydalanib berilgan nuktani tezlik va tezlanish diagrammasini kuring.
4. Berilgan nukta maksimal tezlanishga ega bo`lgan xolatini va eng ko`p inertsiya kuchini kabul kiluvchi bo`g’inni aniklang.
