Research objective: development of principally new pneumatic vibration protection system for car driver's seat with quasi-zero stiffness on a working section of the static characteristic. Research method: theoretical and experimental. Theoretical and practical results: design and mathematical model for determining the static and dynamic characteristics of pneumatic vibration protection system are developed. Design documentation is developed and experimental prototype of vibration protection module is manufactured. Its static and dynamic characteristics are tested under on-line testing conditions. Tree-stage control of driver's car seat suspension height is provided. Novelty and effective-ness: principally new pneumatic vibration protection system for driver's seat with quasi-zero stiffness on a working section of the static characteristic is developed. Vibration natural frequency for driver's seat with vibration protection module devel oped by ITM is less then natural frequencies for suspension seats produced by world-class companies (CAROSA, GRAMMER, ISRINGHAUSEN at al.) by a factor of 1.8. Reduced driver's susceptibility to vibrations is less than the best world-class analogues by a factor of 3. Maximum vibration natural frequency for driver's seat with vibration protection module developed by ITM doesn't exceed 1.2 Hz, what is well bellow the permissible value of 1.5 Hz (under State Standard 20062-91). Application: driver's seats with vibration protection module developed by ITM for UK KV-1 trolley-bus and 45-T tractor are recommended to set onto the PO UMZ tractor and trolley-bus as well to apply to other vehicles that have need for driver's protection against vibration.
