在第五章中，假定在外荷载的作用下，网架结构的单个支撑钢牛腿出现失效，研究在牛腿失效瞬时结构在恒载作用下的承载能力和工作状态。 - Chapter 4 time - dependent computational simulation of the response of cable - suspension feed system in gusty wind based on the time - independent structure finite element method , and with consideration of the movement laws of cabin , a 3 - d time - dependent structure finite element model formulated by a new method named iss method ( instantaneous structure supposition method ) to deal with the vibration response of cable - suspension feed system in gusty wind is presented . in the model , all sources of geometric non - linearity , cable sag and changes of cable geometry due to large displacement , are fully considered
基于时不变结构的有限单元法，在综合考虑馈源舱运动规律的基础上，提出了时变系统的瞬时结构假定法，通过将悬索离散为索杆单元，建立了系统的时变有限元模型，该模型充分考虑了悬索的垂度和大变形等几何非线性因素，应用ne 。 - This thesis , on the basis of modern theories of vibration , ked analysis and finite element method , sets up a kinetic model of piston - linkage mechanism of diesel engine , by i - deas software of sdrc usa , which involves the effect of joint clearance in mechanism . by the presumption of " transient structure " in ked analysis , the mechanism " s dynamic responses in every transient structure conditions are calculated , and it provides a reliable theory basis for the optimization design of diesel engine
本课题基于现代机械弹性动力学理论以及有限元分析方法，利用美国sdrc公司的- deas软件，对含运动副间隙的柴油机的活塞、连杆机构建立了动力学模型；运用ked分析中的“瞬时结构”假定，计算出了机构在各瞬时结构条件下的动态响应，从而为柴油机优化设计提供了可靠的理论依据。
