随着航空航天技术的发展和轻量化要求,复合材料在机翼上的应用比重日益增大。为研究复合材料机翼结构的力学性能,本文采用ABAQUS有限元软件建立了某型复合材料机翼的有限元模型,结合实际工况对机翼工艺结构进行仿真模拟。研究表明,仿真手段可极大提高研制效率,是机翼研制的有效工具;共固化工艺能够有效减少紧固件数量,进而降低由应力集中带来失效的风险。 相似文献

As a new support platform of information technology for social development, virtual reality technology(VRT) has been widely used in many fields. Here, the concept and important features of VRT are summarized first. Then, the analysis requirement for VRT in design, display, operation and maintenance training, and state monitoring for aerospace products is elaborated. This is followed with a review of foreign and domestic policy planning of VRT, and their application in aerospace. Last, future development of VRT is discussed. 相似文献

航天用纤维增强金属层合板 总被引:2,自引:0,他引:2
迄今铝合金仍是航空航天产品的主要结构材料,但它目前正受到纤维增强聚合物和新近崛起的纤维增强金属层合板(FRML)的强有力的挑战。这些新颖材料具有强度高、质量轻、模量高、膨胀系数低和耐疲劳性能好等优点。因而自它们一出世,就受到航空航天界的重视,文中对纤维增强金属层合板的制作方法和它的力学性能作了简要介绍。 相似文献

China's aerospace industry is facing a major task of increasing the reform of aerospace management system and speeding up civil-military integration, which leads to an urgent demand for new aerospace think tank products. Thankfully, with "information space" as the carrier, the "systems science" as the guidance, and QIAN Xuesen's "metasynthetic wisdom system" as the core, QIAN Xuesen think tank provides the decision support for China to develop an aerospace knowledge economy and to continuously enhance the "space soft power". In this paper, the framework of the meta-synthetic wisdom system guided by systems science is presented, the relationship between basic ideas of QIAN Xuesen think tank and meta-synthetic wisdom system is explained and the construction items of aerospace hall of the workshop for meta-synthetic engineering(aerospace HWMSE) are analyzed. 相似文献

This paper provides theoretical underpinnings for further discussions on the future direction of the international aerospace community in an era of globalization. It points out that changes in the international distribution of resources are placing strains on the basic operating principles of the current technology control regime, but at this stage the social groupings do not appear to be in place to overturn the current paradigm. Instead, this paper suggests that current operating principles could be modified in order for the current regime to keep pace with globalization. These changes would include: (1) a shift in the monitoring mechanism of the Missile Technology Control Regime (MTCR) requiring looser supervision but greater transparency; (2) greater inclusion of private industry as a stakeholder in MTCR proceedings; and (3) much more focus on the list of prescribed technologies to include only those which are most critical to the development of military missiles. 相似文献
