基于Hypermesh10.0固定式起重机结构仿真模型构建研究

摘要

Based on the geometric features of the fixed crane with single frame, it used software Solidworks to build a three-dimensional assembly model and exported it to a stp file. Then importing assembly into Hypermesh10.0 and using a variety of element types to build a FEA simulation model including fixed crane overall structure, which can be delivered to direct calculation. The purpose is to achieve more realistic motion simulation and critical structural strength check for a fixed crane operation under multiple loading conditions.%根据单臂架固定式起重机结构几何设计特征，基于Solidworks建立三维装配体模型并导出为stp格式文件，将其导入Hy⁃permesh10.0后，采用多种网格单元类型，建立了一个可直接计算的固定式起重机整体结构FEA仿真模型，目的是为了实现固定式起重机在多工况作业下更真实的运动仿真和关键结构强度校核。
