 Biography:

 

  • Dr. Wang-Chuen Lin is currently an assistant researcher of the National Center for Research on Earthquake Engineering (NCREE), the National Applied Research Laboratories (NARL) in Taiwan.

  • Dr. Lin’s researches are related to structural control technology and large-scale testing for structures and equipment. He has actively published international journal papers and conference papers as well as many technical reports and books. In addition, he has performed many tests for project-specific velocity-dependent dampers and full-scale seismic isolators at NCREE Laboratory. His extensive research effort and considerable accomplishments have been widely implemented into many domestic seismic design codes and specifications. He continues to carry out on-site research and deliver academic papers in passive control technology. 

 

 Speech Abstract:

 Seismic Isolation Technology for High-Precision Equipment and Facilities in High-Tech Factories

 

  • Seismic vulnerability and performance requirements of high-precision equipment and facilities in high-tech factories

  • Introduction of seismic isolation technology and its advantages over conventional design

  • Sloped rolling-type seismic isolator developed by NCREE

  • Practical application of NCREE’s isolator in Taiwan

  • Earthquakes are inevitable in Taiwan. A frequent moderate earthquake may affect regular operation of most important facilities and industries, thus, greatly impacting people’s life and Taiwan’s competitiveness. When most structural elements remain intact during or after an earthquake, the desired performance of a building may not be achieved if the housed equipment or facilities are damaged. This situation has often occurred. For instance, high-precision equipment and facilities of high-tech industries have not remained functional.

  • The rolling-type seismic isolator developed by the National Center for Research on Earthquake Engineering (NCREE), the National Applied Research Laboratories (NARL), provides a most effective seismic isolation strategy for critical equipment and facilities in the relevant industries and organizations. The isolator designed with a multi-roller mechanism on sloped surfaces, together with a friction damping mechanism, can effectively prevent the important equipment or facilities above from shaking, malfunction, and even damage. The transmitted acceleration can remain essentially constant regardless of the earthquake intensity. The built-in damping mechanism can significantly reduce the isolation displacement. In addition, the isolator has an inherent gravity-based self-centering capability after an earthquake.

  • At present, the isolator has been practically applied to many domestic and international industries and organizations. The protected equipment and facilities in these practical applications were intact and still operational without shutdown under numerous real earthquakes, indicating that the device could effectively reduce the direct and indirect losses, as well as have significant advantages for Taiwan’s productivity and competitiveness.
