Abstract :
Based on the Euler beam model and assumptions and using cableway as a practical engineering example, surface roughness parameters of suspension cables are considered and fully analyzed in this study. By introducing the Hertz contact model, the governing equations of coupled vibration between the car and skyline are established. Subsequently numerical solutions for vibration response are derived by using the Newmark method. Numerical simulation examples show that the different response of cable displacement, carriage and hanging payloads do significantly depend on cable roughness. The research result also indicates that the cable displacement curve is significantly different under various states including static, dynamic and considering non-smooth external excitation. Considering the coupling of non-smooth cable dynamics, dynamic displacement of carriage and other hanging objects due to non-smooth external excitation, it is concluded that fluctuation at the maximum cable deflection is profoundly significant. The result also indicates that non-smooth external excitation greatly stimulates instability of suspension cable, thus leading to randomly alternating stress of the cable. The skyline, subjected to superimposed displacements from static, dynamic, and non-smooth excitations, will inevitably experience accelerated fatigue damage. This degradation directly compromises its operational safety and reduces its serviceable life. The analytical analysis and simulation result provide useful comparison from a theoretical point of view and also as practical benchmark reference for engineering ropeway designs.

Abstract :
尽管索道系统在各类工程领域中得到广泛应用,但目前针对双跑车吊装索道系统在吊装过程中的响应问题尚缺乏有效的动力学分析理论.以工程中常见的双跑车吊装索道为研究对象,基于桥式起重机的起吊原理,对双跑车吊装索道系统的起吊过程进行了动力学建模.综合考虑悬索结构与跑车轮钢非线性接触问题,引用赫兹接触理论,得到了跑车与悬索的等效接触刚度;根据悬索结构的特殊性,将其假设为细直长梁结构,得到起吊点处的等效质量.在悬索结构的跨中最不利作业点处设立两种起吊方案,结合工程实例计算获得两种起吊方案下的技术参数,分析了等效刚度和等效质量与起吊点位置之间的关系.选择在一种起吊方案下,结合起吊阶段划分分析和数值计算,获得每阶段下的初始条件,运用牛顿第二定律和影响系数法建立系统的动力学模型,并利用Matlab进行数值仿真.仿真分析结果表明,起吊过程中重物、跑车的竖直位移和重物的转动位移均存在较为明显的响应,在起吊过程中重物、跑车存在微小的竖向移动,且重物会产生微小的转动情况,在起吊末阶段,即重物离地瞬间,钢索结构会产生除了静张力以外的动张力进而引起整个系统的振动.所建立的动力学分析理论能够为双跑车吊装索道的工程设计提供一定的理论指导.

Abstract :
Numerical procedure plays a key role in tackling the solutions of nonlinear dynamical systems. With the advent of the age of big data and high-power computing, developing efficient and fast numerical algorithms is an urgent task. This paper extends the Lie derivative discretization algorithm to the nonautonomous nonlinear systems and investigates the numerical solutions of the systems. The periodic solutions of three different classical nonlinear systems are calculated, and the results are compared to those values calculated from the Runge-Kutta fourth-order algorithm, which demonstrated that the Lie derivative algorithm has the advantages of large time step and short computation time.

Abstract :
As an indispensable accessory, retaining clips on pipes are usually modeled as simply supported or fixed end boundaries. In this paper, a dynamic model of a pipe without fluid, with fixed-fixed ends and restrained by a middle clip is established. Different from the previous modeling that ignores the width of a clip, the clip is modeled as a rigid body with a certain width, which is elastically connected to the base. The effects of clip width, thickness, material parameters, and connection stiffness on the natural vibration of the pipe are presented. Moreover, to illustrate the necessity of the proposed model, a dynamic model of a half pipe is extracted with a clip as one end boundary. According to the two models, the natural frequencies and modes of the pipe are calculated and compared. Some meaningful results are obtained. The clip parameters influence the natural frequencies of the pipe nonlinearly. When calculating the natural frequencies of the pipe, ignoring the clip width or modeling the clip as a boundary will cause a noticeable error. The symmetry of the modes and the numbers and locations of modal nodes change as the clip stiffness changes. Furthermore, modal shapes of the symmetric modes change noticeably as the clip thickness or width increases. The locations of the maximum modal displacements may change as the clip width varies. In summary, a novel and valuable dynamic model of the retaining clip is proposed in this study. The vibration of a pipe restrained by a clip can be more accurately described. Influence laws of clip parameters can be used to guide the design and vibration measurement of pipes with clips.
