Vibration excitation system

2001年秋季和2004年秋季，瑞尔森大学土木工程系分别开始提供硕士和博士学位课程。2010/2011学年，研究生班在校生143人，其中博士35人，硕士30人。学生)。这些学生中大约有50%注册在结构/材料工程专业。2003年，本系建立了一个新的大型结构实验室，以取代旧的实验室。在过去的几年里，申请人和他的同事们努力扩大该实验室的能力，除了使用最近购买的4500-kN压缩试验机进行有限循环载荷试验外，还可以进行单调载荷试验。本实验室急需振动激励系统（即动态作动器系统）来扩大研究生实验研究的范围。

In fall 2001 and fall 2004, the Civil Engineering Department of Ryerson University started to offer Master's and Ph.D. programs, respectively. In the 2010/2011 academic year, 143 graduate students have registered into the graduate program (among them 35 Ph.D. students and 30 M.A.SC. students). Approximately 50% of these students are registered in the Structural/Materials Engineering Stream. In 2003, the department has established a new large-size structures laboratory to replace the old one. During the last few years, the applicant and his colleagues strived to expand the capabilities of this lab to conduct monotonic load tests in addition to limited cyclic load testing available using the recently-purchases 4500-kN compression testing machine. This lab is in urgent need of vibration excitation system (i.e. dynamic actuator system) to widen the scope of experimental research conducted by graduate students.
