某400型随车起重机特性分析

Analysis on the Characteristics of a 400-type Vehicle Crane

为了深入研究折臂式随车起重机的性能,从运动学、动力学、强度理论及稳定性等方面展开分析。首先,建立某400型起重机运动学数学模型,对吊点包络图、速度、加速度进行分析,为后续的动力学和起重特性分析做准备;其次,建立随车起重机的Creo动力学仿真模型,并分析了各个构件的受力情况;最后,结合强度和稳定性分析研究存在的问题及下一阶段工作计划性能,并绘制起重作业图。

In order to study the folding arm type with the performance of truck crane from kinematics, dynamics, strength theory and stability analysis. First of all, the establishment of a 400-type crane kinematics mathematical model, the hanging point envelope, the velocity and acceleration, were analyzed for the subsequent dynamics and characteristics analysis of preparation; secondly, the Creo dynamics simulation model of truck crane was estab- lished, and the stress of each component was analyzed. Finally, combined with the strength and stability analysis of the existing problems, the next stage work plan performances were studied and the heavy work was drawn.
