起重机吊装事故状态再现技术的研究

Study on simulation technology of the crane hoisting accident

运用有限元理论、调查数据及专家经验,建立起重机吊装事故模型,模拟吊装工况并真实地再现了事故发生过程中载荷变化和分析吊装索具的受力情况,提高了事故再现的精度,寻求为事故责任的认定与鉴定提供科学的理论支持。

Through using the finite element theory,survey data and expert experience,the paper establishes the model of the crane hoisting accident,which simulates the hoisting working conditions and truly makes the accident happening process to reappear,thus to analyze the forces of the hoisting riggings,improves the accuracy of the accident simulation and provides scientific theory support for the affirmation and identification of the accident＇s responsibility.
