摘要
由单自由度系统中支承的运动规律及达朗伯原理得到运动微分方程,再利用线性系统的叠加原理,分析系统中被支承质量的振幅及与支承振幅、频率比和阻尼比之间的关系,并由图线具体分析,还对隔振方法进行了分析。
By means of superposition principle of linear system and movement differential equation formulated according to Dalembert＇s principle and law of support motion in a linear system,this paper analyses the relations between the supported mass amplitude and the support amplitude,frequency ratio and damping ratio.Moreover,it analyses vibration isolation methods through specific analysis of drawing line.
