Abstract

Questions of a mode of behaviour and rest of drivers, vibrations on a berth of the truck, the influencing road traffic safety are considered. It is noticed that drivers can spend a considerable part of time to ways at long trips on a berth and vibration negatively affect their condition. Together the driver spends a considerable part of time to ways on a berth and vibration negatively affect its condition. The mathematical model of fluctuations of the driver on a berth and the blocksheme of its realisation in package Matlab/Simulink is offered, allowing a settlement way to define level of vibrations on a berth. Probe of influence of a layer pad of a pillow on level of vibrations on a berth is conducted. The estimation of level of vibrations on a lorry berth is given. It is revealed that in 1/3 oktave bands of frequencies 2,5; 3,1; 4 Hz excess of level of admissible vibrations on 25-50 % takes place. To lower level of vibrations it is possible only by perfection of the basic suspender of the truck. It is established that change of a thickness of a layer pad of a pillow of a berth practically does not influence change of level of vibrations of the driver in a prone position. The choice of a thickness of a layer pad for a seat pillow is more caused by physiological factorsmaintenance of an equal distribution of pressure upon a body of the driver and blood circulation system. To lower level of vibrations it is possible by application springs with small number of sheets or a berth or cabin pneumocushioning.
