中文摘要:在Pro/E中建立了喷杆喷雾机机架的三维模型,在Hypermesh中建立了机架的有限元模型,并导入到ANSYS中进行了自由模态分析,并通过模态实验分析了机架的振动特性并验证了有限元模型的准确性。结合模态分析结果,分析了外部激励对机架动态特性的影响,发现发动机1、2阶往复惯性力的频率会导致机架共振。通过谐响应分析得到机架的振动情况,提出了避免机架与发动机共振的方案,对比了减振前、后的机架位移响应幅值。结果表明,安装橡胶减振元件后机架的动态特性得到明显改善,提高了整机的操纵舒适性。

Abstract:A 3-D model of a sprayer was built with Pro/E,and its finite element model was developed by using Hypermesh. It was imported to ANSYS for free modal analysis. With analysis of vibration characteristic and accuracy of the finite element model, the modal experiment was carried out. Combined with the modal analysis results, the influence of external excitation on the frame was analyzed. It was found that engines first-order and second-order reciprocating inertial force frequency can cause frame resonance. Harmonic response analysis was carried out to obtain the vibration result of the frame. The method of avoiding resonance between frame and engine was proposed. The frame’s displacement response was compared before and after vibration reduction. The results showed that dynamic performance and ride equality of the frame was effectively improved. 

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.
