基于Stewart双三角型机构多维减振座椅的参数优化设计

针对驾驶员座椅多维隔振的问题,采用Stewart双三角型并联机构作为座椅悬架的主体结构,根据人体的敏感频率范围和整车的固有频率,对悬架系统进行了参数优化设计。研究表明,经优化设计的Stewart双三角型并联悬架能保证人体-座椅悬架系统在垂向、俯仰、侧倾三个较重要方向的固有频率既远离整车的固有频率,又避开了人体的敏感频率范围。

Parameter optimization design of multi-dimensional vibration damping seat based on Stewart double triangle mechanism

For the problem of multi-dimensional vibration damping for driver's seat,Stewart double triangle mechanism was used as main structure of seat's suspension. Parameter optimization design was then executed accord to the vehicle's natural frequencies and sensitive frequency range of the human body. Researches show that the natural frequencies of Stewart double triangle parallel suspension not only avoid the vehicle's natural frequencies,but also away from the sensitive frequency range of the human body in vert...
