波阻板隔振设计方法及优化
|
摘要
从实际应用的角度出发,提出波阻板(WIB)的设计方法及其优化设计:假设WIB均为圆板,详细研究了在经济投入一定(某强度等级的WIB混凝土体积不变)的情况下,如何合理确定圆形混凝土WIB的厚度与直径之比(厚径比),以使隔振效果达最佳。
As a new way of vibration isolation,Wave Impedance Board(WIB) is applied in engineering practice.The design method of WIB is put forward from the view of practical application.In the assumption of WIB as a circular plate in optimal design,and to make the better isolation,the paper studies reasonable determination of the thickness-to-radius ratio of circular concrete in detail in economic investment.
