中文摘要:基于虚拟仪器开发平台,采用图形化编程语言LabVIEW建立了一套多通道振动测试和分析系统,运用加速度传感器测定了雷沃谷神牌GN601—CR2Q型谷物联合收获机割台不同测点及不同工况下水平、垂直和轴向的振动信号,并对振动信号进行了时域及频域分析。对联合收获机割台振动测试结果表明,割台的振源最主要的激励为割刀传动系统,割台水平方向的振动量最大并且割台振动最大的部位位于割台的过桥。其中割刀传动系统的惯性力引起的振动频率为10Hz,发动机惯性力引起的振动频率为30Hz,割台的固有频率为68.8Hz。

Abstract:A multi-channel vibration system for testing and analysis based on virtual instrument platform were established using the advanced graphical language LabVIEW. The header vibration signal (horizontal, vertical and axial direction) of Lovol combine harvester GN601—CR2Q at different sites under different conditions was measured by using the acceleration sensor. Time domain vibration and frequency domain were analyzed. The results of the header vibration test showed that the main excitation of the vibration sources was header transmission system, the horizontal vibration of header was largest and the largest header vibration position was the header conveyer. The frequency of inertia force of the cutter driving system was 10Hz. The frequency of inertia force of the engine was 30Hz. The natural frequency of the header was 68.8Hz.

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.
