Inertia parameter identification of power assembly of ATV

为获取沙滩车(ATV)动力总成惯性参数,对沙滩车动力总成进行了惯性参数辨识试验。为获取准确的激励点、响应点坐标,使用三维扫描仪测量。利用质量线法计算了沙滩车动力总成惯性参数。为研究激励点数量对沙滩车动力总成惯性参数的影响,对比了不同数量激励点对应的沙滩车动力总成惯性参数。研究表明,至少19个激励点、8个三方向响应点可以辨识到稳定的沙滩车动力总成惯性参数。

In order to obtain the inertia parameters of ATV powertrain,the inertia parameter identification test of ATV powertrain was carried out.In order to obtain accurate coordinates of excitation point and response point,3D scanner measurement was used.The inertia parameters of ATV powertrain were calculated by mass line method.In order to study the influence of the number of excitation points on the inertia parameters of ATV powertrain,the inertia parameters of ATV powertrain corresponding to different numbers of excitation points were compared.The research showed that the stable inertia parameters of ATV powertrain could be identified by at least 19 excitation points and 8 three-direction response points.
