利用新疆伊犁河谷的伊宁县SPOT5遥感影像，在ERDAS IMAGINE 9．2软件平台下，通过二次变异分析算法和三次非对称分析算法提取纹理信息。基于图像的光谱特征和纹理特征进行监督分类，然后根据地物的空间分布进行“分区分类处理”。结果表明，伊宁县的总体分类精度提高了19．34％， Kappa系数提高了0．247。利用霍城县遥感图像进行分类方法验证，同样取得了较好的效果，表明该方法可在伊犁河谷土地利用分类中进行推广应用。

The SPOT5 remote sensing image of Yining County in the Ili Valley of Xinjiang Uygur Autonomous Region was used in this paper.The texture information was extracted by means of Variance and Skewness algorithms supported by ERDAS IMAGINE 9.2 soft-ware .Based on the spectral and texture information , supervised classification was used to get the classification images of Yining Coun-ty.Then the partition classification based on the spatial distribution of ground features was processed .The results showed that , the o-verall classification accuracy increased by 19.34%and Kappa coefficient increased by 0.247.To test this classification method, the remote sensing image of Huocheng County was used , and a good result was also achieved .All these showed that the classification method could be prompted to the Ili Valley Land Use Classification .

以某无人机支柱式主起落架为例，基于LMS Virtual．Lab Motion和LMS Imagine．Lab AMES-im开展联合仿真，首先利用VL Motion建立主起落架落震动力学分析模型，再根据缓冲器参数建立AMESim缓冲器液压模型，最后通过两个软件的联合仿真，计算该无人机主起落架的缓冲性能。以油针几何形状为设计变量，基于iSIGHT优化平台集成AMESim建立该无人机主起落架的缓冲器优化流程，通过优化计算得到该油针的最佳截面积参数，缓冲器最大轴向力降低了10．49％，缓冲器效率提高了12．54％。
