Vibroprotective and Energetic Properties of Oscillating System Equivalent to Vehicle Suspension with Pendular Regulator on Shock Absorber

The purpose of the article is to study the vibroprotective and energetic properties of vehicle suspension with pendular regulator on shock absorber in a two-mass oscillating system. A mathematical model of suspension with pendular regulator on shock absorber in a two-mass oscillating system is developed. The analysis of the research results with the vibroprotective properties of the two-mass oscillating system with pendular regulator on shock absorber under harmonic and random road impact is presented. The study revealed that the suspension with pendular regulator on shock absorber in the two-mass oscillating system provides higher vibroprotection of a vehicle body and higher energy-saving properties compared to a classic unregulated suspension. Using pendular regulator on shock absorber in the two-mass oscillating system leads to the increase in the tire deformation in the area of spectrum corresponding to the high-frequency resonance of the system.
