The investigation involves the creation of stronger gravitational fields to act on laboratory models using a modulated magnetic field. The goal is to produce a model that behaves like the actual structure, and to offer the convenience of a non-revolving experimental setup. The system is to expand the ability to excite models with calibrated dynamic signals such as impact, harmonic excitation and complex earthquake motions. Verification of small model tests is accomplished by conducting an experiment on an existing full-scale structure or by analytical predictions. This project is one supported under the Creativity Awards for Undergraduate Engineering Students.

这项研究包括利用调制磁场创造更强的引力场来作用于实验室模型。我们的目标是建立一个与实际结构相似的模型，并提供非旋转实验装置的便利。该系统扩展了用校准的动态信号（如冲击、谐波激励和复杂地震运动）激励模型的能力。小型模型试验的验证是通过在现有的全尺寸结构上进行实验或通过分析预测来完成的。本项目为“工科本科生创意奖”资助项目。
