Study on Performance of A New Type of Ball Bearing for Force Measurement

球型支座是连接桥梁上部结构和下部结构的重要构件,为及时观测和获取球型支座的受力状态,便于桥梁结构的健康监测,研制一种新型的测力球型支座,采用光纤光栅传感技术检测支座的竖向承载力,通过测力试验证实,该新型测力球型支座能有效收集桥梁结构的实际受力数据,可为评估桥梁结构的健康运营提供有效的科学依据。

Spherical bearing is an important component connecting the upper and lower structures of bridges. In order to observe and obtain the stress state of the spherical bearing in time and facilitate the health monitoring of the bridge structure,a new type of force-measuring spherical bearing is developed. The vertical bearing capacity of the bearing is tested by using fiber bragg grating sensing technology. The force-measuring test proves that the new type of force-measuring spherical bearing can be effectively collected.Collecting the actual force data of the bridge structure can provide an effective scientific basis for evaluating the healthy operation of the bridge structure.
