| 1 | 基于机器视觉技术的高压断路器机械特性诊断显示文摘高压断路器是电力系统中重要的控制和保护设备,其可靠性会影响到电力系统的安全运行。调查显示高压断路器的主要故障为机械故障,需要对高压断路器机械特性进行检测。因此利用高速相机搭建了断路器机械特性测量平台,利用该测量平台对ZN63A–12型真空断路器进行试验研究,测量高压断路器合闸弹簧动态振动特性,同时将应力松弛故障弹簧与正常弹簧进行对比,探究弹簧应力松弛故障对断路器合闸弹簧振动特性的影响。此外,以高压断路器合闸过程为例,利用测量平台对四连杆机构动态运动过程进行拍摄,并通过计算得到合闸过程中连杆夹角变化曲线。研究结果表明:正常与应力松弛弹簧的振动特性存在明显区别,同时利用测量平台测量得到连杆之间的夹角由139.7°变化到175.6°,夹角变化了35.9°,与实际值相符合。 | 王立军 张拓 刘光伟 张佳灏 | 2020 | 高电压技术2020，46，6： | 15 |
| 2 | 振动状态下螺旋弹簧运动状态模型显示文摘螺旋弹簧受到冲击载荷时,特别是多股螺旋弹簧,由于有质量、惯性,再加上自身的谐振,钢丝材料的弹性变形、多股螺旋弹簧中钢丝与钢丝之间的相对滑移而产生的摩擦阻力等诸多因素,簧圈的运动将变得非常复杂。基于此,建立一套用于检测振动状态下螺旋弹簧任意簧圈的运动状态模型,用于揭示振动状态下螺旋弹簧任意簧圈的位移、速度、加速度随时间的变化规律,特别是用于检测冲击载荷下多股螺旋弹簧的内部变形规律。试验结果表明:螺旋弹簧运动状态分析模型结合非接触多通道检测装置,可以成功地揭示振动状态下螺旋弹簧任意簧圈的运动状态随时间的变化规律,为螺旋弹簧的动态设计理论的建立提供了试验依据。 | 王时龙 张明明 周杰 赵昱 李小勇 田波 | 2012 | 机械工程学报2012，48，1： | 8 |
| 3 | Three-stage Method for Identifying the Dynamic Model Parameters of Stranded Wire Helical Springs显示文摘The dynamic behavior of the stranded wire helical spring is described by a modified Bouc-Wen model while the model parameters must be identified using an identification method and experimental data. Existing identification methods usually relies either solely nonlinear iterative algorithms or manually trial and error. Therefore, the identification process can be rather time consuming and effort taking. As a result, these methods are not ideal for engineering applications. To come up with a more practical method, a three-stage identification method is proposed. Periodic loading and identification simulations are carried out to verify the effectiveness of the proposed method. Noises are added to the simulated data to test the performance of the proposed method when dealing with noise contaminated data. The simulation results indicate that the proposed method is able to give satisfying results when the noise levels are set to be 0.01, 0.03, 0.05 and 0.07. In addition, the proposed method is also applied to experimental data and compared with an existing method. The experimental data is acquired through a periodic loading test. The experiment results suggest that the proposed method features better accuracy compared with the existing method. An effective approach is proposed for identifying the model parameters of the stranded wire helical spring. | ZHAO Yu WANG Shilong ZHOU Jie LI Chuan SUN Shouli | 2015 | Chinese Journal of Mechanical Engineering2015，28，1： | 4 |

| 7 | Digitalized Accurate Modeling of SPCB with Multi-spiral Surface Based on CPC Algorithm显示文摘The main methods of the existing multi-spiral surface geometry modeling include spatial analytic geometry algorithms, graphical method, interpolation and approximation algorithms. However, there are some shortcomings in these modeling methods, such as large amount of calculation, complex process, visible errors, and so on. The above methods have, to some extent, restricted the design and manufacture of the premium and high-precision products with spiral surface considerably. This paper introduces the concepts of the spatially parallel coupling with multi-spiral surface and spatially parallel coupling body. The typical geometry and topological features of each spiral surface forming the multi-spiral surface body are determined, by using the extraction principle of datum point cluster, the algorithm of coupling point cluster by removing singular point, and the 'spatially parallel coupling' principle based on the non-uniform B-spline for each spiral surface. The orientation and quantitative relationships of datum point cluster and coupling point cluster in Euclidean space are determined accurately and in digital description and expression, coupling coalescence of the surfaces with multi-coupling point clusters under the Pro/E environment. The digitally accurate modeling of spatially parallel coupling body with multi-spiral surface is realized. The smooth and fairing processing is done to the three-blade end-milling cutter's end section area by applying the principle of spatially parallel coupling with multi-spiral surface, and the alternative entity model is processed in the four axis machining center after the end mill is disposed. And the algorithm is verified and then applied effectively to the transition area among the multi-spiral surface. The proposed model and algorithms may be used in design and manufacture of the multi-spiral surface body products, as well as in solving essentially the problems of considerable modeling errors in computer graphics and engineering in multi-spiral surface's connection available with approximate methods or graphical methods. | HUANG Yanhua GU Lizhi | 2015 | Chinese Journal of Mechanical Engineering2015，28，5： | 0 |
