    Opis:
    In this paper, an innovative active seat suspension system for vehicles is presented. This seat suspension prototype is built with a shear guidance mechanism, an air spring, a hydraulic shock absorber and end-stop buffers. The acceleration particular signals are measured by using Inertial Measurement Units (IMUs) placed on the seat and the human head. As the excitation, the horizontal vibrations are applied. As an alternative to the classical Fourier approach, the Wavelet Transfer Function (WTF) is introduced to describe the effectiveness of particular seat suspension. In both of the system cases, the human head reaction is investigated by using the Matlab package.

    Opis:
    A motorcycle or moped helmet is currently mandatory, and provides basic protection to the user of a motor-powered two-wheeler against the possible consequences of a road accident. A wide market offer of various protective helmets allows one to choose from many different design solutions used by the manufacturers. The introduction of a protective motorcycle helmet is associated with the need of meeting the conditions set out in legal regulations. In recent years there have been changes in the legal provisions regarding to protective helmets and the conditions imposed on helmets are becoming more and more restrictive. There have also been changes in the conditions for conducting the helmet approval tests. Regulations valid in Europe include the Economic Commission of Europe (ECE), whereas regulations in the United States are created by the Department of Transportation (DOT). Despite the advanced construction of protective helmets, various test methods, and changes in legal regulations, the problem of the effective protection of the heads of two-wheeler users remains valid. The article presents an actual state of constructions for motorbike helmets, safety level, testing methodology and actually applicable law regulations. This analysis includes a wide medical description of motorcyclist injuries and helmet obstacle impact behaviour. Further studies are required to estimate the head and neck injuries caused by accidents involving motorcycles and other materials. Therefore, construction and testing methods should be developed accordingly. This review presents the current state of knowledge that can be used as the basis for helmet tests and medical assessments of body injuries.

    Opis:
    The aspects related to the dynamic modeling of the mechanical properties of motorcycle tires following the practical application of research methods have been analyzed for many years. A test stand was constructed for the examination, and a mathematical model was proposed to calculate tire parameters. This study aims to develop the characteristics of the radial dynamic stiffness of a pneumatic tire depending on the pressure in the tire, speed of the beater simulating tire slipping onto a small obstacle lying on the road, and impact damping. The testing device was designed to simulate a sudden strike of a tire on a stiff foreign body lying on a road plane. The experiment was performed for three different values of air pressure in the tire, beater rate, and impact energy of the tested wheel. The dynamic radial stiffness of pneumatic tires decreased with increasing deformation speed and pressure. Presented in the paper research methodology can be an introduction to further, more complicated research, where will be taken into consideration factors such as wheel rotation, driving or breaking the wheel, friction, etc. The proposed methodology can be extended to assess the dynamic adhesion coefficient during tire impact loading.
