- 单气压驱动+内置永磁体，利用磁弹性滞回产生蠕动波
- 仿真与实验验证了流体流动特性，证明设计可行性
- 适合微流控、生物医疗等需无接触输送的场景
流体输送广泛应用于工业、环境和生物医学领域。蠕动泵通过变形弹性管实现流体无接触输送，具有高效安全的优点。以往机械、气动或磁驱动方式常导致结构复杂、控制繁琐。本文提出一种软膜泵，仅通过单一气压输入结合嵌入式被动磁体，实现蠕动运动。通过建模分析了驱动机制与系统动力学，并进行数值模拟预测内部流场。仿真中观察到的磁弹性滞回行为，经概念验证原型实验成功验证。
原文摘要 · Abstract (English)
Pumping fluids is fundamental to a wide range of industrial, environmental, and biomedical applications. Among various pumping mechanisms, peristaltic pumps enable efficient and safe fluid transport by deforming an elastic tube without direct contact with the working fluid. Although previous studies have introduced mechanical, pneumatic, or magnetic actuations to drive membrane deformation, these approaches often lead to complex pump architectures and control schemes. In this study, we present a soft membrane pump that achieves peristaltic motion through a single pneumatic input combined with an embedded passive magnet. The actuation mechanism and system dynamics were analyzed and simplified through modeling. Numerical simulations were conducted to predict the internal fluid flow, and the magneto-elastic hysteresis behavior observed in the simulations was successfully validated by experiments with a proof-of-concept prototype.
