摘要
基于HY-Z04型剪式座椅,以SK37-6型膜式空气弹簧作为弹性元件,构建了带附加气室空气悬架座椅振动试验系统。试验研究了节流孔开度、簧上质量及激励频率等因素对座椅振动特性的影响规律,研究结果表明,座椅悬架的固有频率随节流孔的增大而减小;节流孔产生的阻尼随节流孔的增大先变大后变小;当激励频率较低时,节流孔开度对座椅加速度的影响不大,当激励频率高于某值后,节流孔开度越大,对应的加速度均方根值越小;节流孔对加速度均方根值的影响具有明显的非线性。
Based on HY-Z04 type scissors linkage seat and SK37-6 type diaphragm air spring used as elastic element,the experimental system consisting of scissors linkage seat and air suspension with auxiliary chamber was established.The effects of orifice opening,mass on spring and actuating frequency on the vibration characteristics of seat were experimentally studied.The results show that,the natural frequency of seat suspension will decrease with the increase of orifice diameter,and the damping caused by orifice wi...
