      Gaimei Zhang, Xiaoli Song, Yue Shi, Fan Su, Yue Cao

      Abstract

      The main reason is vibration and shock in the circulation for the damage of packaging product in the logistics process. The impact is one of the main factors, which causes product damage and packaging failure. To prevent the damage, drop test of packaging system must be carried on. However, this detect is generally destructive for products and so much samples are consumed. In this paper, the models of laptop and its cushioning packaging system are built, and the drop analysis of the system is developed based on ABAQUS software. The stress of the laptop during drop is simulated. Comparing the laptop without cushion and the packaging system using the cushion, the results show that the stress is different for two types, and the stress of laptop without the cushion is bigger than the other.

   6. Study on the Cushion Performance of the Cushion Material Composed of EPE and Corrugated Paperboard

      Xiaoli Song, Gaimei Zhang, Jiandong Lu, Lizheng Zhang, Shuo Zhang

      Abstract

      This paper analyzes the static compression performance of the cushion material which is composed of EPE and corrugated paperboard. The cushion coefficient and the stress-strain curve are investigated under different thickness of EPE and different corrugated paperboard. The results show that the static cushion coefficient is not proportional to the strain with the increased height of corrugated paperboard. When ε < 58%, the static cushion coefficient of the cushion material which is composed of A corrugated paperboard and EPE is smaller. The cushion performance is better than the one composed of AB corrugated paperboard and EPE. When ε ≥ 58%, the static cushion coefficient of the cushion material which is composed of AB corrugated paperboard and EPE is smallest. And the static cushion performance is best. With the increase in EPE thickness, the static cushion coefficient is not proportional to the thickness. The increase in thickness does not necessarily improve the cushion performance of the cushion material.

   12. Study on Shelf Life Prediction of Edible Oil in BOPP/VMPET/CPP Flexible Packaging

       Yayun Liu, Qifeng Chen, Guangxue Chen

       Abstract

       This experiment explores changes of peroxide value and acid value of the edible oil that is over-wrapped with BOPP/VMPET/CPP composite film and then stored at 35 °C, 50% RH, and predicts the shelf life of edible oil under this condition by means of dynamics equation. At the same time, the barrier property of the film was evaluated by measuring the initial permeability and moisture permeability of the film and the tensile properties at different time periods. Research shows that peroxide value and acid value in the edible oil increase with time linearly, tensile properties of the soft package decreased gradually with time. Under the experimental conditions, the oil packed in BOPP/VMPET/CPP composite film had a shelf life of about 70 days, far below that of polyester plastic bottle packaging in the market for sale, so the application of flexible packaging in edible oil still need to explore.

      Jialing Zhang, Jimei Wu, Yan Wang, Kaikai Li, Li’e Ma, Fan Zhao

      Abstract

      According to the problem of the poor rolling bearing signal under the high background noise of the high-speed printing press, the fault diagnosis method is proposed, which is combined with Ensemble Empirical Mode Decomposition (EEMD) and spectrum kurtosis (SK). Due to the traditional EEMD has the defect of directly rejecting the high-frequency section impact fault signal, this paper adopts the three principles of EEMD noise reduction to carry on the improvement processing. The fault vibration signal of rolling bearing was decomposed into several intrinsic mode functions (IMF) under different characteristic scales with EEMD. The false signal of IMF is removed by the three principles of noise reduction to construct a new fault signal. In this paper, the bandwidth and central frequency of band-pass filter are selected by SK method and the envelope spectrum of the filtered signal is analyzed. The result shows that the combination of improved EEMD and SK method are effective than the method of conventional EEMD and envelope analysis. It promotes fault recognition rate of printing press bearings.

      Xinpei Li, Shaozhong Cao, Hongfeng Xiang, Zhengjie Jin, Mingdao Wang

      Abstract

      Due to the low efficiency in the installation of the bearing sleeves for the printing machines and the great damages to the operators in the installation process, a robot of sleeve installation for printing machine is proposed. For the robot, the precise measurement and accurate model are the basis of completing assembly. Firstly we resolve the inverse solutions by the kinematics of 6-DOF parallel platform (Jiang et al. in Proc Inst Mech Eng 8, 2015, [1]) to obtain the Jacobian matrix between the thrust of rods and generalized force. Secondly, the kinetic equation among thrust rods, the platform position and speed is established by Lagrange equation (Sirouspour and Salcudean in Trans Robot Autom 17:173–182, [2]). Finally, the strategy of using probe-into measure tooling is put forward, which establishes the relative pose relations among the readings of probe-into measure tooling, platform and the through-holes. Thus, eventually, we can obtain the relationship between the readings of probe-into measure tooling and the thrust of rods, laying a foundation for the accurate controlling of robot based on probe-into measure tool.

      Kaikai Li, Linlin Liu, Jimei Wu, Meng Li, Shenghui Yong

      Abstract

      With the development and application of additive manufacturing technology, the mechanical properties of parts have become more important. The functional parts with complex shape have become an urgent need in manufacturing industries. The performance of FDM built parts exhibit high dependence on process parameters, and it can be improved by setting suitable parameters. Hence, the work focuses on extensive study to understand the effect of four important parameters such as fill density, layout angle, filling shape and layer thickness on the tensile stress of orthogonal test specimen. The results show that the important parameters affecting the mechanical properties of parts are the filling density and filling shape, and the process parameters of tensile strength are optimized. The optimization of process by range analysis gives the maximum tensile strength and the optimum value of filling density, layout angle, filling shape and layer thickness as 50%, 0°, Honeycomb shape and 0.15 mm respectively. In this paper, the optimization of process parameters can effectively improve the mechanical properties of FDM built parts.
