【摘要】 建立了模拟轮转机刀式折页机构的振动测试实验台,通过改变试验台杆杆间运动副的间隙量,测试了不同速度下摇杆的运动加速度。结合理论值,对测试数据进行了时域加速度和频域振幅波形分析。分析结果表明,运动副间隙的存在使折页机构高速运行平稳性降低、振动加剧,且此现象随着间隙量的增大而愈发严重。更多还原

【Abstract】 A vibration test bench simulating Web Press’s Fold Mechanism was established.By changing the clearance volume between link-bars,tested the rocker’s acceleration at different speeds.Analysised the test data through time-domain waveform and frequency-domain waveform.The experimental results shows that the presence of clearances at joints reduced the stability of high-speed fold mechanism and resulted in a severe vibration,the phenomenon became more serious with the increase of clearance volume.更多还原
