摘要
为了明确有效质量法控制振型截断的物理本质,从力的响应和能量的角度进行了两种数学推导,揭示了有效质量法的控制公式,阐明了其物理意义,得出有效质量法有很强的实用价值的结论,值得推广应用。
To know the exact meaning of controlling shaking offcut by valid quality methods, this article makes two mathematical conductions from reaction of force and power, reveals the controlling formula of valid quality methods, elaborates its physical meaning, concludes that valid quality methods have strong practical value, and worthy of spreading.
