| Abstract: | Based on working properties of hydraulic face-shovels, the interlocking movement between arm and bucket is first elaborated. Moreover, a kinematical analysis is conducted for quadrangular mechanism in hydraulic face-shovels. Thereafter, a mathematical mode is established, subject to a number of motional constraints. Under the VBTM programming environment,an implementation procedure is postulated for quadrangular mechanism analysis.Finally,this approach is applied and evaluated in the practical design of a specific hydraulic face-shovel. It is detected that the range of interlocking region brings significant impacts on excavation performance of the hydraulic cylinder. |
