Abstract

The invention discloses an application method of parametric simulation in safety assessment of a bridge grab ship unloader. The method comprises the following steps: simplifying a model, and selecting a unit type and a coordinate system; creating a parameterized model; parameterizing boundary conditions; parameterizing intensity analysis and modal analysis, and parameterizing a result viewing process; guiding a stress test and a vibration test according to the intensity analysis and the modal analysis, and comparatively analyzing an intensity analysis result, a modal analysis result and a stress test result respectively; and building a parametric simulation analysis system for the bridge grab ship unloader. According to the practical demand on the safety assessment of the bridge grab ship unloader, a VB development tool is combined with a parameterization technology of ANSYS, and modeling, the boundary conditions, an analysis process, result viewing and the like are parameterized with the parameterization technology to develop a set of parametric simulation analysis system for the bridge grab ship unloader, so that simulation analysis has the characteristics of high speed, accuracy, high practicability and the like.

Description

technical field [0001] The invention relates to an application method of parametric simulation in the safety evaluation of a bridge grab ship unloader. Background technique [0002] Cranes are an important infrastructure for national economic construction, and are also facilities closely related to people's lives, among which ship unloaders play a pivotal role. The main function of the metal structure of the ship unloader is to bear the self-weight and external load of the ship unloader, and form the necessary working system and movement space to complete the various functions of the ship unloader, so the safety of the metal structure is very important. The bridge grab ship unloader is the main material reclaiming equipment of the bulk cargo terminal. Its safety performance is directly related to the normal operation of the terminal. Once the bridge grab ship unloader fails, a chain reaction will occur, resulting in The entire berth loading and unloading process system was ...
