| 摘 要： | 主振系上与消振器耦连的部件被称为减振体。本文通过推导传递函数求得减振体完全消振的结构和参数条件，给出选择消振器安装位置和工作环境的若干见解，在低阻尼和小失调率条件下建立了减振体残存振幅和消振器参数之间的函数关系，利用映象原理导出了计算阻尼振动系统动力消振器结构参数的近似公式，并用算例阐明了计算的详细过程。

| Abstract: | This paper discusses some mechanical problems of dynamic tuned absorber for multidegree of freedom systems. The construction and parameter condition of absorbers by which vibration can be perfectly absorbed are deduced and some views about selecting the location and operating environment of absorbers were suggested. The functional relation between remanent amplitude and parameters of absorber was determined under conditions of low damping and small rate of detuning. Some approximate formulas for calculating construction parameters of the dynamic tuned absorber for multidegree of freedom system were derived. The calculation process was illustrated by two examples. |
