摘要
本文从理论上提出了一种适合于轮式拖拉机振动模型．模型中考虑了人体与拖拉机的振动耦合作用．并将人体模化为多自由度非线性系统．理论数值模拟结果表明，所提出的减振结构的力学模型对降低拖拉机座椅的振动是有效的，为进一步进行座椅减振结构设计提供了理论依据．
This paper put forward vibration model theoretically, that can represent the vibration of drivertractor and involves coupling effect of body to tractor. and that models body as a multi -freedom- deg rses non-linear system. Simulated results show theoretically that the mechanics model of seat suspension structure is valid for reducing the seat vibration and provides a theoretical basis for designing of the new seat suspension structure.
