中文摘要:以受预应力直梁无阻尼模态作为Galerkin映射的谱函数,求解静电-非线性梁耦合微器件的动力学问题。对器件的Pull-in吸合和释放动态过程进行仿真,将结果与有限元结果和已有文献的结果比较来验证模型的有效性,研究表明:用这一方法建立的模型不仅能够对不同载荷情况进行多次快速仿真,也能够对不同几何参数和材料参数的同类型器件进行快速计算,仿真精度高且减少了计算费用。

Abstract:An undamped mode of pre-stressed straight beam was used as spectral function of Galerkin mapping to solve the dynamic problem for electrostatic-nonlinear beam coupling. The dynamic process of Pull-in and Pull-off for device was simulated. The proposed model was validated by comparing with the finite element results and the literature results. It was indicated that the proposed model not only had fast simulation ability with different action loads, but also suit for fast predicting the device characters variation with the different geometry size and different material parameters. The calculating results had sufficient accuracy and the computational costs were significantly reduced.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
