pallet is the basic containerized unit in logistics industry, and has widely application value in commodity circulation.Railway pallet transportation can improve efficiency in handling operation, quality of freight transportation, decrease freight damage, guarantee transportation safety, and helpful to connection between railway transportation and other transportation mode, develop multimodal transport.This paper points out integration of pallet resources and establishment of railway pallet sharing system is the future direction of Railway pallet transportation through detailed analysis of present situation and advantageous conditions in Railway pallet transportation;discussion on establishment railway pallet sharing system in pallet standard, system exchange nodes and network, pallet associated company through international advanced system and mature operation management mode.

Study on the establishment of pallet sharing system of railway transportation

Early-Stage Aqueous Corrosion-Related Defects in Heavy Ion Irradiated P92 Ferritic/Martensitic Alloy

To understand irradiation accelerated the corrosion behavior further, the early-stage aqueous corrosion-related behavior was investigated in heavy ion irradiated P92 ferritic/martensitic alloy by multiple characterization techniques. The oxide film was formed at 350 °C/10 MPa water for 80 h. The surface morphology of irradiated specimen was different from that of unirradiated specimen. Many grains were fused together in irradiated specimen. Doppler broadening spectroscopy of slow positron beam shows that the existence of irradiation defects could accelerate the production and accumulation of corrosion-related defects in the deeper region of the oxide film.

Improving the exploration of vacancy evolution in P92 alloy under Fe ion irradiation using positron annihilation

A new Roller Forks is put forward. And a novel rollers mechanism is used in the forks. As the key component of the forks, the main girder’s strength is studied in detail, including its stiffness, maximum stress and the corresponding minimal safety factor. The analysis results show that the girder meets the design requirement.

Strength Analysis of Main Girder of the Roller Forks

Using the novel rollers mechanism, a new Roller Forks is put forward. As the key component of the forks, the main girder’s strength is studied in detail. According to adopting different materials, its maximum distortion and stress are analyzed. The analysis results can be used as the base of the material selecting of the main girder.
