摘要
设计制作一个可大幅度连续调节并能测出C值的阻尼器,在水平面内任意方向都有阻尼作用,且阻力系数C相等,特别适合于模型减振的优化试验。用于广东小北江蓑衣滩新站房模型减振实验研究,取得了很好的结果,并从中找出了减振的最佳C值。文中还提出了计算阻尼器C的经验公式,与实验标定结果比较一致。
A damper whose drag coefficient C can be adjusted and measured in a large range was made. It offers effective damping with the same coefficient C in all directions on a plane. Therefore it is very suitable for optimum mitigation vibration test of a model. Using it to the experimental study on the vibration mitigation of Suoyitan new station building model, good results are obtained and the optimum C is found out. An experimental formula is presented to calculate the coefficient C which can well fit with the calibration results.
