摘要
本文介绍了汽车式液压折臂起重机在起重作业时的动态模型。文章建立了液压折臂式起重机的动态模型，其中考虑到了臂架油缸、折臂油缸和伸缩油缸的粘弹性。该模型是针对起重机在起吊负载时的复杂操作而建立的，在这种情况下，臂架油缸、折臂油缸和伸展油缸同时启动。拉格朗日方程 II 型用于建立描述机械系统运动的微分方程系统。在此基础上，文章分析了起重机在起重作业时的动态参数。文章的结果是液压折臂式起重机控制问题的基础，以提高起重机在运行过程中的性能和可靠性。
DYNAMIC ANALYSIS OF THE HYDRAULIC KNUCKLE BOOM CRANE WHEN LIFTING LOADS OPERATIONS
This article presents the dynamic model of a truck-mounted hydraulic knuckle boom crane when lifting loads operations. The article develops a dynamic model of a hydraulic knuckle boom crane considering the viscoelasticity of the boom-luff cylinder, knuckle cylinder, and extension cylinder. Modeling is constituted for the complex operation of the crane when lifting loads, in which the boom-luff cylinder, knuckle cylinder, and extension cylinder are simultaneously activated. The Lagrange equation of type II is used to build a system of differential equations describing the motion of the mechanical system. On that basis, the article analyzes the dynamic parameters of the crane when lifting loads operations. The results of the article are the basis for the hydraulic knuckle boom crane control problem to improve the performance and reliability of the crane during operation.
