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。
Design and manufacture of a damper that can be continuously adjusted and can measure C value have the damping effect in any direction in the horizontal plane and the resistance coefficient C is equal, which is especially suitable for the optimization test of model vibration reduction. It is used to study the vibration reduction experiment of the new station building of Xiaobeijiang Beach in Guangdong Province. Good results have been obtained and the best C value of vibration damping has been found out. In this paper, the empirical formula for calculating the damper C is also proposed, which is consistent with the experimental calibration results.
