1.结构的共振峰和阻尼之间的关系目前,随着现代科学技术的发展,宇航器、飞机、车辆、舰船、海洋平台、高层建筑、机床等常常不得不解决结构的共振问题,这是因为它们处于一个宽带激振的环境.抑制共振峰最好是从振源着手,而在许多情况下,有些振源如喷气机、火箭、机器的动力装置正是工作需要的动力;又如地震力、波浪力、路面的不平等则是无法避免的环境条件,由于激振频带较宽,用改变刚度或质量的方法常不足以使结构的固有频率躲
1. Relationship Between Formations and Damping of Structures At present, with the development of modern science and technology, spacecraft, aircraft, vehicles, ships, offshore platforms, high-rise buildings and machine tools often have to solve the structural resonance problem, which Because they are in a wide-band excitation environment.It is best to suppress the formant from the vibration source, and in many cases, some vibration sources such as jets, rockets, the power plant is the engine of work and another Earthquake force, wave force, road surface inequality is unavoidable environmental conditions, due to the wide excitation frequency band, with the method of changing the stiffness or quality is often not enough to make the natural frequency of the structure to hide
