| 1. | No accommodation or recreational or catering facilities should be exposed to excessive vibration 居住舱室或娱乐或膳食服务设施不应暴露于过度振动中。 |
| 2. | To reduce the excessive vibration of a high - speed rotor system at the critical speed , a friction damper with a flexible support structure is introduced 摘要为了抑制高速滚动轴承转子系统在通过临界转速时的过大振动,本文采用了摩擦阻尼弹性支承结构。 |
| 3. | Function and advantages : it features such functions that protects metal against abrasion and corrosion while muffling unwanted noise caused by excessive vibration 功能与优点:具有防锈蚀、防渗水、隔音降噪、堵漏修补、防撞击、美丽的万里外观等功能,可以提供持久的保护作用,全面延长车底盘使用寿命。 |
| 4. | So the solution is obtained by ansys . at those places with excessive vibration along the lightway , two field measures ( wave impending block and isolation trench ) were adopted to reduce vibration 并在振动较大的地方采用了wib ( waveimpendingblock )和隔振沟两种减振措施,同时对减振效果进行了分析比较,得到了较为理想的结果。 |
| 5. | During the shipbuilding in major shipyards worldwide , plenty of problems are generated out of shaft alignment , which results in the over - tolerance of main engine crank shaft , high temperature of bearing and excessive vibration 在船舶的建造过程中,世界各大船厂,都多次出现过轴系校中的问题,导致主机拐档差超差,轴承高温或造成振动过大等。 |
| 6. | Field measurements are carried out to record the vibration data of a template offshore platform . dynamical characteristics and responses are analyzed to search the cause of the excessive vibration of the platform under mildly sea state 进行了海洋平台现场振动测试,并利用振动测试数据进行了平台动力特性、动态响应分析,研究了海洋平台过度振动的原因。 |
| 7. | The capacity and size of modern hydrogenerator set are larger with rapid developing of hydroelectric engineering , specific speed of hydraulic turbine increase too . the phenomenon of excessive vibration in some load area is founded ubiquitously 随着水电工程建设的高速发展,现代水轮发电机组的容量和尺寸日趋增大,比转速也相应提高,普遍出现在某些工作区域内振动过大的现象。 |
| 8. | 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。 |
