    摘要:

    采集农用轮式运输车在草地、泥地及15.1°坡度砂石路等3种不同果园路况下运行时的振动加速度信号,利用LabVIEW信号处理模块对运输车的振动加速度信号进行分析,通过对振动加速度信号进行二次积分得到振动位移信号,研究农用运输车果园路谱振动信号特征并进行相关性分析。结果表明,农用轮式运输车的速度和装载质量对草地的路面不平度信号影响显著;坡度对路面不平度信号的影响最大,其次是速度,最后是装载质量。

    Abstract:

    This article is aimed to research the vibration acceleration signal of agricultural wheeled transporter when working in grassplot, mud road and 15.1° slope of dinas road conditions. And then the vibration acceleration signal was input in the LabVIEW's signal processing model to analyze and extract its feature. At last,through the correlation of vibration displacement signal,which is acquired by twice integral operation based on the vibration acceleration signal,its characteristics were analyzed and extracted. The results of the vibration displacement signal indicating that speed and load weight significantly affect the pavement roughness of grass. The significant value of slope,speed and load weight indicating that slope has the biggest effect on the pavement roughness signal followed by speed and load mass. 
