Grab Bucket Optimization Design Based on the Kinematics and Dynamics Analysis
Grab bucket is one of the most important assemblies of the grab dredges whose performance largely relies upon the construction of the bucket.Dynamics is carried out stressing on the two critical points,commencing status and terminating situation,for the greatest grabbing and cutting force; and so is done on kinematics concentrating the three representative points,A,B,and C,with position,velocity,and acceleration,respectively,with which almost all of the points on the bucket may be obtained for the three kinematic parameters.Optimal desgin have been dorne with objective of the proper momentum and thrust force and constraint of weight,width,ratio of weight and capacity,quotiety of the rope,ascent and descent velocity of the bucket.
