Study of dynamics characteristics and comfort parameters of passenger car with independently rotating wheels
Santrauka
The authors of an article compare the dynamic characteristics of cars with one-piece wheel sets and wheel sets with independently rotating wheels by comparing Nadal criterion values and their laws of change when the car runs on various curves and straight sections of the railway. The studies show that in curves of low radius, laws of change of Nadal criterion values are fundamentally different than in straight railway sections; it has a significant impact on the comparison of dynamic parameters of passenger cars with one-piece wheel sets and wheel sets with independently rotating wheels. Authors use Sperling’s comfort index to assess the riding comfort. They compare the riding comfort of passenger cars with one-piece wheel sets and wheel sets with independently rotating wheels based on Sperling’s comfort index.
