This article is divided into two parts—in the first part, authors inform about their testing device that enables the acquisition of results from uniaxial and multiaxial fatigue tests (the bending−torsion combination). We present the approaches used during designing and building the testing device. The direct implementation of the research in the second part will concentrate on implementing the acquired results for the frame design of a vehicle worked out by the authors. The three-wheeled vehicle has the front steered wheel suspended in an unconventional way. This original design can cause an increased load on the vehicle’s frame. This can be apparent mainly during driving through curves. Therefore, the fatigue curves of the tested material (EN AW 6063) will be implemented from the point of view of its usability in operation. A vehicle frame is most often loaded by bending and torsion. The authors assess the influence of welding on the fatigue life of this unique unconventional vehicle by determining the fatigue curves of the material for its production. The stresses achieved on the test specimens fully correspond to the load of the frame (in welds) during its operation.

“…Since the designed three-wheeled vehicle is considered as a vehicle, which could be eventually used for common urban operation. Therefore, in addition to just described technical changes modification of the current design of a frame [15] will be necessary to perform in such a way to meet requirements on one hand with regard to passengers' protection against weather conditions (direct sunlight, wind, rain, etc.) and on other hand regarding the improvement its aerodynamic properties [27].…”

Vibrational properties of road vehicile are ussually evaluated according to two criterions, i. e. in terms of comfort for passengers and in terms of drive safety and roadway load. The topic of this article is focused on evaluation of passenger's ride comfort of a three-wheeled road vehicle. From the ride comfort point of view vertical vibration is decisive. Vertical vibration is given by obtained accelerations in given position on an assessed vehicle when it is driving on a road with various surface qualities within required time intervals. In the vehicle's design phase its vibrational properties are detected and evaluated by means of simulation computations on a virtual model. In our research we have assessed ride comfort of the three-wheeled vehicle, which were designed in our workplace. For purposes of dynamic analyses we have used multibody approach using Simpack software. The objective of this work is verification of the relevance of the current mounted suspension system for the greater driving speeds range of the three-wheeled vehicle and for different road qualities.

“…Based on described above, the proper operation of the shock absorbers is extremely important in terms of running properties of vehicles. In the opposite case, the insufficiently effective shocks absorbers or even damaged shock absorbers can cause a number of deficiencies [29][30][31], among others the following: • Time extension of vibration of individual bodies of a vehicle while running on track unevenness, • Excessive vibration of a vehicle body, when it runs on successive track unevenness, • Large deviations of a vehicle body at the improper frequencies generate excessive values of accelerations, which deteriorate the ride comfort for passengers [15,32], • Due to high amplitudes of vibrations, a wheel can lose the contact with a track, which means really dangerous situation in terms of the running safety, • It leads to the worsen effectiveness of braking and directional stability of a vehicle (a normal force is lower) and causes a danger of a skid mainly during running in curves [33].…”

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.
