Simulation Analysis of Stepless Frequency Modulation Hydraulic System for Double Steel Wheel Vibratory Roller
摘要
Abstract
In order to broaden the application range and improve the compaction performance of vibratory roller,the stepless frequency modulation device's principle of vibratory roller is studied.Based on the software AMESim,a simulation model is established.And then typical surface layer compaction conditions and frequency conversion compaction conditions of vibratory roller are simulated.The simulation result shows that the start-up time of the stepless frequency modulation hydraulic system is about 3 seconds,and the difference of vibration frequency between front and rear wheels is not more than 0.18 Hz under stable compaction condition.It shows that the performances of surface compaction and frequency conversion compaction for double steel wheel vibratory roller are good,which provides a theoretical and an experimental bases for application of stepless frequency modulation for vibratory roller.关键词
