Complete dynamic calculation of lattice mobile crane during hoisting motion

Dynamic responses of hydraulic crane during luffing motion

“…This is similar to the principle of ''kinematic forcing'', which proposed by [4]. In our previous works [1,2], we have found that the method of ''kinematic forcing'' with the assumed profiles of the driving velocity and acceleration could not accurately describe the driving outputs during start-up and braking of the system. It is seemed that these assumed start-up and braking velocity profiles are based on experience.…”

“…Using the proposed method, we have presented complete dynamic models for rotating and hoisting motion of rotary crane [1][2][3]. In this paper, the luffing dynamic behavior will be considered.…”

Strength and Elastic Stability of Cranes in Aspect of New and Old Design Standards

“…That caused that the designed and produced cranes according to this standards were heavier. Detailed standards provisions with ready formulas facilitated calculations of loads in the typical cases, but in other cases did not indicate the clear calculations models [11][12][13][14][15][16]. There were paradoxes in design process like very high loads assuming in some construc-tional details (much higher than it really was), only for not to cause stability loss of some low strength and less important elements.…”

Dynamic Simulation of the Harvester Boom Cylinder

“…For this reason, many crane dynamics studies have been reported in the literature [4]. Most of the published articles concentrate on dynamic responses of booms during rotating and hoisting motions, such as Guangfu Sun's [5] research of the lifted load motion considering changes in rotating, booming, load hoisting, and support system. Chin et al [6] demonstrated the effects of a platform motion on the dynamic stability of the boom crane.…”
