Proposal of a Method for Detection of a Damaged Hydraulic Shock Absorber in a Vehicle's Suspension System

Abstract

In principle, every vehicle is equipped by a suspension system, which usually consists of springs and shock absorbers. The main purpose of the suspension system is to eliminate vibration of sprung and unsprung masses. Therefore, the proper operation conditions of the shock absorbers affect in a fundamental way total running properties of vehicles. However, during operation, shock absorbers are being worn out or they can even be damaged. Then, such a situation is unwanted and it has to be detected as soon as possible. The content of this article is focused on analysis of vehicles’ shock absorbers defects. Methods for detection of possible shock absorbers faults are presented. Further, a proposal of the method for detection of a state of a hydraulic shock absorber during its operation is presented. The method uses identification of the temperature change of a hydraulic shock absorber during operation.

Material’s Strength Analysis of the Coupling Node of Axle of the Truck Trailer

“…Potential damage, whatever its cause, is modeled and estimated in modeling. The finite element method (FEM), sometimes referred to as finite element analysis (FEA), is widely used in the literature [16][17][18][19][20][21] to achieve essentially two purposes. One of the aims of this study is to analyze the stresses of the current semi-trailer design or to optimize its design.…”

The Analysis of Pneumatic Wheel Rim Deformation While Hitting an Obstacle

“…The issues of road transport safety are widely discussed in the literature, for example in [11][12][13][14][15][16]. Many authors pay attention to vehicle safety systems: braking systems, including Anti-lock Braking System (ABS) and Electronic Stability Program (ESP) [17][18][19][20][21][22], vehicle suspension systems [23][24][25][26], tires [27][28][29][30], tire pressure monitoring systems (TPMS) [31,32], and other systems [33][34][35][36]. In [37], tests mapping the damage to the wheel of a tire on a vehicle on a special test stand are described.…”
