【摘要】：【目的】为改善高空作业平台的调平性能,研究长管道效应对调平性能的影响.【方法】通过建立长管道模型,分析了影响调平性能的管道参数,并结合长管道作用下的调平系统仿真模型,分别研究管道材质、长度、直径及布管方式对调平性能的影响规律.【结果】硬管材质能够较软管材质使系统响应时间缩短0.4~0.6s;管道长度由1m增加至40m可使系统响应时间由0.05s延长至0.3s,压力损失由0.6bar增大至24.8bar;管道直径由5mm增大至20mm,使调平稳定时间由1.1s延长至2.2s,压力损失由69.9bar减小至1.7bar;阀前布管较阀后布管加快系统响应时间约0.2s,但易引起压力冲击.【结论】长管道效应对高空作业平台调平性能的影响显著,长管道参数化分析形成调平系统的优化布置及参数选择原则,对高空作业平台的调平性能改善提供了参考.
