Analysis Of The Influence Of Temperature Field On Hulll Local Strength

Zhenxiao Shi, Yifeng Guan

Because the asphalt is kept at 180 C during transportation, the asphalt temperature has an effect on the structural stress of the ship hull. This paper mainly discusses the effect of temperature on the local structural strength of the asphalt ship. Taking an asphalt ship as an example, the whole cargo tank area is modeled by using finite element software MSC. Patran and MSC. Nastran. The model is established by referring to the relevant provisions in the Code for Construction of Steel Inland River Ships. The finite element mesh of the model is generated by choosing the appropriate element type. Applying temperature boundary conditions, the calculated temperature field is applied to the model in the form of load, and other boundary conditions are applied to establish a variety of working conditions, calculate the structural strength, and obtain the stress distribution of the hull. Considering the thermal stress with or without temperature, the effect of temperature on hull structure is analyzed.
