摘　　要：弹簧振子及其受迫振动是物理学中的一个重要模型,在工程领域具有广泛的应用。地面振动噪声是诸多精密测量实验中的关键制约因素,对地面振动噪声进行隔离与抑制的方案大多基于弹簧振子响应特性。本文针对基于弹簧振子的隔振系统,通过直接引用弹簧振子受迫振动的响应特性并引入惯性力,提出一种在非惯性系中分析隔振系统性能的方法,并给出了一个最简单的分析示例。在大学物理教学中引入这种基于非惯性参考系的分析方法,有助于学生理解弹簧振子的隔振特性,同时也可以加强对物理学科中多个知识点之间联系与应用的教学。Spring oscillator and its forced vibration is an important model in physics and has wide applications in engineering field.Ground vibration noise is the vital constraint in many precision measurement experiments.Most of the schemes to isolate and suppress ground vibration noise are based on the response characteristics of spring oscillators.Aiming at the vibration isolation system based on spring oscillator,this paper proposes a method to analyze the performance of vibration isolation system in non-inertial frame by directly quoting the response characteristics of forced vibration of spring oscillator and introducing inertial forces,and gives a simple analysis example.The introduction of the analysis method based on non-inertial reference frame in university physics teaching can help students to understand the vibration isolation characteristics of spring oscillators,and also strengthen the teaching on the connection and application of multiple knowledge points in physics.
