| 中文摘要: |
| 目的 以振动能量采集器的拾振结构为研究对象，分析阻尼比、频率、非线性系数、弹性系数和激励振幅对振动响应特性的影响。方法 首先对拾振结构建立其物理系统模型，建立模型的动力学方程并进行理论计算。然后，用同伦分析法(HAM)对其响应特性进行计算分析，得到理论计算结果。最后，通过Matlab绘制振动特性基本曲线，得到模拟分析结果。结果 非线性系数对振动响应特性的影响较小；减小弹性系数、增加阻尼比、控制系统频率和激励振幅，可以增大响应振幅。结论 为振动能量采集器拾振结构的优化设计提供理论依据。 |
| 英文摘要: |
| The work aims to analyze the effect of damping ratio, frequency, nonlinear coefficient, elasticity coefficient and excitation amplitude on the vibration response characteristics, with the vibration energy harvester as the research object of the vibration pickup structure. First, the physical system model of the vibration pickup structure and the dynamic equation were established, and the theoretical calculation was conducted. Then, homotopy analysis method (HAM) was used to calculate and analyze its response characteristics, so as to obtain the theoretical calculations. Finally, MATLAB was adopted to draw the basic curve of vibration characteristics, so as to obtain the simulated analysis results. Nonlinear coefficient had little effect on the vibration response characteristics. The response amplitude could be increased by reducing the elasticity coefficient, increasing the damping ratio, and controlling the system frequency and excitation amplitude. This will provide a theoretical basis for optimization design of vibration energy harvester’s vibration pickup structure. |
