Optimization of New Steel Plate Spring in Seismic Steel Bearing
The steel projectile body seismic steel bearing is a new type of bearing that provides necessary seismic resilience and energy dissipation to the bearing through a new steel plate spring added to the outer side of the traditional spherical steel bearing.It ensures the basic repositioning of the bearing after minor earthquakes and absorbs seismic energy during strong earthquakes,allowing for partial repositioning of the bearing after earthquakes to meet the basic requirements for traffic.Firstly,mechanical performance tests were conducted on the new steel plate spring,and a finite element model was established to validate the effectiveness of the bearing finite element model using the test results.Subsequently,dynamic characteristics analysis was performed on both the individual steel plate spring and the overall structure of the steel bearing to study the contribution of the new steel plate spring to seismic energy dissipation.Simultaneously,parametric modeling analysis was conducted on the structure of the new steel plate spring to identify the influence patterns of various parameters.Finally,a multi-parameter fitting was performed on the stiffness and dimensional parameters of the new steel plate spring,resulting in a fitting function and achieving structural optimization of the new steel plate spring dimensions,thereby achieving the goal of material savings and reduced structural space.
