电信设备结构优化与抗震性能提高

Structure Optimization and Anti-seismic Property Improvement of Telecommunication Equipment

模拟地震试验是考察电信设备抗地震性能的一项重要方式,其反映了电信设备在地震中抵抗地震破坏的能力,进而直接影响了国民经济等方面的安全水平。电信设备的主体框架的刚性直接影响着设备的抗地震能力,设备的固有频率可以较为直观的体现出设备的刚性特征。通过利用ANSYS软件对常见形状电信设备的主体框架进行仿真分析,得到提高主体结构中矩形框架的稳定性和改变主体框架的横截面形状均可以很好地改善设备的固有频率。通过对改善前后相关实例进行实际的地震模拟测试,试验结果分析表明了ANSYS仿真的正确性。为地震模拟试验的相关研究提供了一种思路,同时也减少了利用大量实际模拟测试得到所需试验数据的工作量和经济成本。

The simulated earthquake test is an important way to inspect the anti-seismic property of the telecommunication equipment, which reflects the ability of the telecommunication equipment to resist the earthquake damage, and then directly affects the safety level of the national economy, etc. The rigidity of the main frame of the telecommunication equipment directly influences the seismic property of the equipment, and the natural frequency of the equipment can be more intuitive to reflect the rigidity of the equipment. Using the ANSYS to simulate the main frame of the common shape telecommunication equipment, the stability of the rectangular frame and the cross section shape of the main frame can be improved. Through the improvement of the relevant examples to carry out the actual earthquake simulation test, the test results analysis shows that the ANSYS simulation is correct. It provides a way of thinking for the related research of seismic simulation experiments, and also reduces the workload and economic cost of the required test data by using a large number of actual simulation tests.
