Abstract:

？为了给蓄能器在工程机械的应用与参数设置提供参考,针对工程机械液压驱动系统压力冲击频繁问题,通过合理选择蓄能器参数,有效提高该系统的性能。建立了皮囊式蓄能器的数学模型,从理论上分析了影响蓄能器性能的参数与选择方案,并利用AMESIM仿真软件与工程机械液压底盘模拟试验台进行了仿真分析与试验验证。结果表明:蓄能器预充气压力为系统工作压力80%～90%时,既能有效吸收系统的压力冲击,又能保证系统的快速稳定性;蓄能器容积越大,系统响应速度越慢;蓄能器连接管路直径越小,系统压力冲击越明显;连接管路越长,系统压力冲击会增加,但是增加不显著;对于工作在剧烈波动载荷下的工程机械液压驱动系统,应根据系统的压力变化幅度配置不同固有频率的蓄能器组,并分段配置各蓄能器的参数来加宽吸收压力波动的频率宽度与压力冲击范围。
