The project is developing a multi-purpose smart vibration platform with controllable stiffness and damping ratio for in-classroom demonstration to improve student learning. The platform uses shape memory alloy (SMA) springs, whose stiffness can be adjusted by electrical hearting, and a magneto-rheological (MR) fluids damper whose damping ratio can be controlled by an electromagnet. The smart vibration platform is being used for a variety of demonstrations. The smart vibration experiments are significantly enhancing student learning involving dynamic systems, mechanical and structural vibrations, and vibration controls in multiple departments, including mechanical engineering, civil engineering, and engineering technology. University students, professors, and industrial supporters according to pre-determined evaluation metrics will evaluate the platform and its use as an educational tool. A total of 10 different instructors at four diverse institutions will assist in the assessment and dissemination of the results of the project.

该项目正在开发一个多用途的智能振动平台，具有可控的刚度和阻尼比，用于课堂演示，以改善学生的学习。该平台使用形状记忆合金（SMA）弹簧，其刚度可以通过电加热来调节，和磁流变（MR）流体阻尼器，其阻尼比可以通过电磁铁来控制。智能振动平台正在用于各种演示。智能振动实验大大提高了学生的学习，涉及动态系统，机械和结构振动，以及多个部门的振动控制，包括机械工程，土木工程和工程技术。大学生、教授和行业支持者将根据预先确定的评估指标评估该平台及其作为教育工具的用途。来自四个不同机构的10名不同教员将协助评估和传播该项目的成果。
