Taking spring-mass system as mechanics model to researchsingle-freedom vibration systems characteristic has universal practical value. 根据单自由度振动系统数学模型,利用M atlab软件设计了单自由度振动系统的数学仿真实验。 3) vibrational degrees of freedom ...
Typical vibration tests in the aerospace industry implement single degree of freedom input (either translation or rotation) due to the perceived complexity in control while meeting specific specification levels. However, there are cases where controlling all six degrees of freedom simultaneously can be ...
