Abstract. In this paper the experimental-numerical method of determining,
dynamic parameters i.e. mass moments of inertia and coefficients of motion
resistance of the multimass rotating systems and energy provided to the
examined aeroplane wheels with tyres is presented. Considered rotating
system is the essential part of a large machine for the dynamic investigation
of pneumatic aeroplane tyres, which simulate dynamic load of the examined
wheel with tyre. The presented method uses differential equations of motion
and regression method. The paper includes the results of the computation
for the chosen rotating system.
DINAMIKA I IDENTIFIKACIJA SISTEMA
ROTACIONE MAŠINE ZA ISPITIVANJE AVIONSKIH
GUMA
U ovom radu prikazan je eksperimentalno-numerički metod određivanja dinamičkih
parametara tj. masenog momenta inercije i koeficijenta otpora kretanja
sistema sačinjenog od više rotirajućih masa i energije obezbeđenih za ispitivanje
avionskih točkova sa gumama. Razmatrani rotacioni sistem je ključni element
velike mašine za ispitivanje avionskih pneumatika, koja simulira dinamičko
opterećenje ispitivanog točka sa pneumatikom.
Prikazani metod koristi diferencijalne jednačine kretanja i metod regresije.
Rad obuhvata i rezultate proračuna za izabrani rotacioni sistem.
