RESEARCH, APPROXIMATION OF CHARACTERISTICS OF PILLOWS OF SEATS AND INFLUENCE ON VIBRATION OF DRIVER OF TRUCK

Abstract

Are considered a situation developed in the field of modelling of fluctuations of vehicles (truck), the attention on low vibroisolation properties of seats is focused. One of the reasons which the weak level of scrutiny of real characteristics of a pillow of a seat is. The technique of tests of pillows of seats is resulted, dependences of change of their parametres on a thickness of a layer pad of a pillow and a rubber category are received.The advanced mathematical model of a pillow of the seat, providing good coincidence of the peak-frequency characteristic in a strip of frequencies of 2–20 Hz and the block-schema of its realisation in package MATLAB\SIMULIK is offered, allowing more to model fluctuations on a workplace of the driver of a vehicle more precisely. Pillow influence on vibration properties of seats is investigated.
