本文叙述并分析了目前各港使用最广泛的8t、16t轮胎式起重机的振动现象,提出轮胎式起重机自振特性的简单计算模型,其计算结果与调查资料一致。文内还简要地讨论了减振装置,提出有关轮胎式起重机减振分析与措施的几点初步意见。
This paper describes and analyzes the vibration phenomenon of the 8t and 16t wheeled cranes currently used most widely in Hong Kong and proposes a simple calculation model of the natural vibration characteristics of the tire type crane. The calculation results are in accordance with the survey data. The paper also briefly discussed the vibration damping device and put forward some preliminary opinions on the vibration analysis and measures of the tire type crane.
