针对车—梁耦合系统动力响应分析,提出并推导了吊重摆动力与移动激励组合模型以考虑吊重运行产生的摆动力及吊车与吊车梁的耦合关系,并通过MATLAB求解得吊车运行过程中吊车梁所受激励,以此作为输入荷载,利用有限元计算分析吊车梁的动力响应并与实际工程实测数据进行对比分析,表明该模型是合理可行的,可应用于吊车动力响应分析。
針對車—樑耦閤繫統動力響應分析,提齣併推導瞭弔重襬動力與移動激勵組閤模型以攷慮弔重運行產生的襬動力及弔車與弔車樑的耦閤關繫,併通過MATLAB求解得弔車運行過程中弔車樑所受激勵,以此作為輸入荷載,利用有限元計算分析弔車樑的動力響應併與實際工程實測數據進行對比分析,錶明該模型是閤理可行的,可應用于弔車動力響應分析。

According to the vehicle-beam coupling system dynamic response analysis,this paper proposed and deduced the carrying swing power and mobile incentive combination model to consider the coupling relationship of swing power caused by carrying operation and crane and crane beam,and through MATLAB solved the vehicle-beam incentive in crane operation process,taking this as the input load,used the finite element calculated and analyzed the dynamic response of crane beam and compared with actual engineering measured data,indicating that the model was reasonable and feasible,could apply to the crane dynamic response analysis.
