The anti-impact ability of shafting affects stability and security of the ship power transmission directly. Moreover, it also cannot be ignored that the rub-impact loads have influence on the torsion vibration of ship shafting. In order to solve the problem of engineering application of reliability assessment under rub-impact loads, a test rig with rubbing generator is established. By carrying out the integrative analysis, the torsional vibration characteristics, such as vibration amplitude and orbit of axle center under the rub impact load are studied. According to the rub-impact conditions obtained through numerical simulation, the experimental verification is carried out on the test rig with rubbing generator. The results show that it is not obvious the influence of rub-impact loads upon the shafting torsion vibration except in special working conditions, that can be simulated by the rubbing generator. The maximum amplitude of torsional vibration is influenced by the radial rigidity as well as the friction coefficient of rubbing body, and the degree of influence is difference under conditions of continuous rubbing and serious rubbing. By adjusting the rigidity of stern bearing, the influence of rub-impact upon shafting can be weaken, which provides a theoretical reference for the safety evaluation of ship shafting

To realize “seamless” connection of ocean port container multimodal transport, efficiently carry out “door-to-door” transport of ocean port containers and overcome the shortcomings of existing highway and railway vehicles, this study takes the standard for heavy-duty container vehicles in TB1335-1996 Railway Vehicle Strength Design and Test Identification Code as the design basis and designs a new ocean port container transport vehicle in combination with automatic guidance technology. This study innovatively designs the automatic lifting system of the bogie and the docking part of the vehicle, introduces the automatic guidance technology and the remote-control technology to optimize the car body structure, and uses the SAP software to carry out the finite element analysis of the car body load capacity and Flexsim software to carry out the simulation analysis on the operation of vehicles. The designed transfer vehicle can improve the transfer efficiency of ocean port containers, reduce the transit time of field and station equipment and container transport links, and improve the level of multimodal transport and comprehensive economic benefits

Limonium bicolor, Vitex trifolia Linn. var. simplicifolia Cham and Apocynaceae venetum are halophyte species with ecological restoration function of saline soil that are widely distributed in coastal areas around Bohai Sea in China. The mechanism of response to salt stress is different between them. The salt-tolerance mechanism, especially for ion homeostasis, of these halophytes varies and is not properly understood. The purpose of the work was to reveal the effect of salinity on ion homeostasis in these three halophyte species. Plant growth, leaf succulence, Na⁺, K⁺ and Cl⁻ concentrations, as well as ion flux were examined at various concentrations (0–100%) of artificial sea water after 10 days. The results showed as follows: the growth of L. bicolor was obviously stimulated under salt stress, while V. trifolia Linn. var. simplicifolia Cham and A. venetum was strongly inhibited. The contents of Na⁺ and Cl⁻ increased with salinity in the three halophyte species, in both the leaves and roots. The accumulation of K⁺ in roots was promoted by salinity except in L. bicolor subjected to 100% artificial sea water concentration. L. bicolor roots showed a lower net Na⁺ efflux compared with the control. By contrast, V. trifolia Linn. var. simplicifolia Cham and A. venetum roots retained a greater capacity for net Na⁺ efflux compared with the control. L. bicolor and V. trifolia Linn. var. simplicifolia Cham roots exhibited a lower and higher net Cl⁻ influx, respectively, than the control, but the differences were not significant. By contrast, A. venetum roots exhibited a Cl⁻ efflux compared with the control. L. bicolor and V. trifolia Linn. var. simplicifolia Cham roots reduced net K⁺ efflux, and L. bicolor even appeared to exhibit a K⁺ influx at certain points in time, whereas A. venetum strongly increased net K⁺ efflux compared with the control. The accumulation and partitioning of ions differed between the three halophyte species, and the salt-tolerance ranking from high to low was L. bicolor, V. trifolia Linn. var. simplicifolia Cham, and A. venetum.
