摘要
采用ANSYS中shell63单元和beam188单元建立吊机整体有限元模型,模拟仿真了吊机静载试验过程,确定了模型的准确性和整体结构的受力状态。对吊机模型进行模态分析与谐响应分析得出其固有频率等特性,为后期改进和优化提供理论依据。研究了在起吊和荡移过程中吊机结构的动力响应,验证了结构的安全性。
ANSYS shell 63 unit and beam188 unit were applied to establishing the finite element model of the whole crane,to simulating the static loading test of crane and determining the accuracy of the model and the stress state of the overall structure. The model modal analysis and harmonic response analysis of the crane was carried out in order to obtain the inherent frequency characteristics,which provided the theoretic basis for later improvement and optimization. At last,the dynamic response of the structure in the lifting and swing shift process was further researched,which ensured the safety of structure.
