基于ADAMS的振动过程频率特性分析

Frequency Analysis for Vibration Process based on ADAMS

机械系统动力学分析软件ADAMS的后处理模块,能够帮助实现模型调试、试验验证、设计方案改进和结果显示功能,从而便于从可视化角度深入研究设计的有效性。以一个简单多体动力学模型为例进行振动分析,采用ADAMS PostProcessor进行数据的后处理,研究仿真分析过程。利用FFT曲线图进行分析,发现动力学模型的加速度频率特性中谱密度幅值的峰值发生在前19～ 20 Hz处,据此可以研究模型系统的性能。

The post-processing module for mechanical system of dynamics analytical software ADAMS can complete the function of model debugging, experimental verifying, scheme improving and result showing. It is beneficial for exploring the effectiveness of the research from the perspective of visual design. Select a simple multi-body dynamics model as an example for vibration analysis, and use ADAMS PostProcessor for data processing to study the simulation analysis process. By FFT graph analysis, it is found that the dynamic model of acceleration amplitude frequency characteristic of spectral density peak occurred in the frequency between 19～ 20 Hz, which can be used to study the performance of the model system.
