Laboratoriya №4 Parametrlari mujassamlashgan ob’ektlarning dinamik matematik modelini tuzi Ishdan maqsad

3 – qadam. Simulink – model faylini L0501.mdl faylini yaratamiz .

S – model konfiguratsiya parametrlarini kiritamiz start time = 0, stop time = 100, Solver Options Type = Fixed step, Solver = ode5 Dormand Prince, Fixed Step Size = 0.001.

4 – qadam. Gildirakning harakatini y1 ni ikkita sources | step bloklari orqali kiritamiz. Buning uchun:

• 
  Modelga step1 va step2 bloklarini kiritamiz;
  
• 
  Step1 blogiga quyidagi parametrlarni kiritamiz: Step time = t1; Initial value = 0; Final value = - hole_depth; Sample time = 0.001;
  
• 
  Step2 ga quyidagi parametrlarni ornatamiz: Step time = t2; Initial value = 0; Final value = hole_depth; Sample time = 0.001;
  

3 – rasm. Avtomobilning gildiragi harakatini modellashtirish

• 
  Signallarni Math operetions | Sum blogi orqali qoshamiz (3 - rasm).
  

Natijani Scope blogiga ulab organamiz va tegishli vaqt oralig'ini tanlab, modeldagi konfiguratsiya parametrlarini boshlash vaqti va to'xtash vaqtini modellashtirishni tekshiramiz.

5 – qadam. Continuous | Integrator bloglari orqali biz 4 – rasmda korsatilganidek, harakat tezligi va tezlanishini ozgarishini aniqlaymiz.

4 – rasm. Integrator blogidan foydalanish

6 – qadam. Prujinanig siqish kuchini hisobga olamiz (Spring Force).

Buning uchun:

• 
  S – modelga Gain signal kuchaytirgichni kiritamiz uni Stiffness deb nomlaymiz va parametrini Gain = k deb belgilaymiz. Bu parameter prujinaning bikirligini beradi qiymati Workspase ishchi oynasiga yoziladi;
  
• 
  S – modelga Sum yigindi blogini kiritamiz va parametriga List of signs = | + - ;
  
• 
  Bloglarni 5 – rasmda korsatilgandek ulaymiz.
  

5 – rasm. Prujinanig bikirligi hisobga olingan modeli

7 – qadam. Porshanning qarshiligi va amortizatorning oz’aro tasiri kuchini hisobga olamiz (Damping Forse):

• 
  Modelga Gain signal kuchaytiruvchi blogini kiritamiz uni Damping Constant deb nomlaymiz va Gain = c deb belgilaymiz. Qiymatini Workspace ishchi oynasiga kiritamiz;
  
• 
  S – modelga Sum yigindi blogini kiritamiz va parametriga List of signs = | - - ;
