Development of a Smart Vibration Platform Experiment

该项目正在开发一种具有可控刚度和阻尼比的多功能智能振动平台，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)弹簧和磁流变液阻尼器(MR流体阻尼器)，形状记忆合金弹簧的刚度可以通过电动心动来调节，磁流变液阻尼器的阻尼率可以通过电磁铁控制。智能振动平台正被用于各种演示。智能振动实验显著提高了学生在机械工程、土木工程和工程技术等多个系的动力系统、机械和结构振动以及振动控制方面的学习能力。大学生、教授和行业支持者将根据预先确定的评估指标对该平台及其作为教育工具的使用进行评估。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。

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.
