桥式起重机吊装过程动力学分析及最大动力响应解算

摘要

吊钩桥式起重机吊装过程中的最大动力响应发生在货载起吊离地和全速下降制动2个瞬间。本文对这2个瞬间动力过程进行详细研究，包括影响因素分析及力学、数学模型的建立等，并用MATLAB软件对一桥式起重机吊装过程的最大动力响应进行解算，解算结果可以作为吊具选用及强度设计的依据。%The maximal dynamic response in the hoisting process of the bridge crane occurs at the two moments of lift-off and bra-king during full speed descent process. The two dynamic processes were researched detailedly, included the influence factors analysis, the dynamics and mathematics model establishment, etc. Then the maximal dynamic response in the hoisting process of one bridge crane was calculated in MATLAB integrated devolopment enviroment, the result could be the warrant of the hoisting tool selection and design.
