wire-pull
1.The assisting mechanism of hammer in dredge haul is to accumulate energy with wire pull, draw inner pole firstly, release by pin framework, acceleratc core piece, strike hammer shell, produce great instantaneous wallop, drag dredge to break op stone immediately, restore with reposition spring, and work again finally.
4.In order to optimize the perpetuation tensioning tonnage of prestressed pier anchor wire of Goupitan arch dam, first the scheme contrast method is adopted to define the perpetuation tensioning tonnage combination of the primary and secondary anchor wire, but the optimization result is that the pull-anchor coefficient is too big; then the body form of the pier is optimized; finally the anchor wire perpetuation tensioning tonnage is optimized by using ANSYS optimization design module based on parametric FEM, the optimization result is acceptable and the Pull-anchor Coefficient is lowered down.
