环境荷载 meaning in English
environmental load
Examples
- Wind load is an environmental load which acts on structure with long - term time , and is also one of the most important loads to control the structural design
风荷载是大跨度空间网格屋盖结构长期经受的一种环境荷载,也是结构设计的主要控制荷载。 - An offshore platform is subjected to the action of environment loads such as the wind , wave , flow and ice etc . . these loads are long - term and consecutive , so an offshore platform exist more serious vibration during its serving life than other buildings in land
海洋平台受风、浪、流和冰等环境荷载的作用，这些外荷载具有显著的长期性、连续性特点，因此，海洋平台在使用过程中存在着较陆上结构更为明显、持续的振动问题。 - The modal parameter identification using natural excitation technique and eigensystem realization algorithm are studied . reasonable results are identified . by introducing statistics to dispose the modal frequency of the structure , the preciseness and precision of the identified system mode are improved
研究了利用环境荷载激励技术和特征系统实现算法进行模态参数识别，引入统计方法对模态频率进行统计平均处理，提高了系统模态识别的准确性和识别精度。 - The vibration , on one hand , will cause fatigue damage , decreasing the platform ' s reliability ; on the other hand , the excessive vibration ca n ' t satisfy the basic psychological requirements of the personnel . hence using smart control technology to enhance the structures " safety and reliability , prolong the service life and ensure the comfort of the personnel has become a very important research subject on ocean engineering and academic fields
这种长期、连续的作用会导致平台在使用过程中发生明显、持续的振动，从而加剧平台的疲劳破坏、降低系统的可靠度，甚至影响平台的正常生产活动，因此近年来，利用振动控制技术来减轻海洋平台在环境荷载作用下的振动问题，日趋重要。
