Method for determining the shock absorber effectiveness in the vehicle suspension to ensure its active and operational safety

Abstract

The article is devoted to the development of a new method for determining the shock absorber effectiveness in the vehicle’s suspension on a vibration stand with vibrating plates, which has greater accuracy and functionality compared to the already known method. The use of the new method will make it possible to reduce the risk of accidents and improve road safety with its widespread introduction.

High Performance Accelerated Tests to Evaluate Hard Cr Replacements for Hydraulic Cylinders

“…Our review of the literature indicated that there are two main approaches on how to evaluate the tribological behavior of hydraulic cylinders. The first one is by mathematical simulation/modeling [16][17][18][19][20], whereas the second one is by developing new lab-scale test procedures [21][22][23][24]. Currently, both approaches have certain limitations.…”

“…Lab-scale tests are more applicable for material development, as long as they correlate well with the component behavior. Unfortunately, until now lab-scale tribological tests [21][22][23] focus only on the frictional aspect, which determines the performance of hydraulic cylinders, but not on the wear which dictates the lifetime of this component. Moreover, the lab-scale tests that do measure wear [24] use simplified contacts and different contact geometries that do not closely resemble the actual contact.…”
