In this paper the hydraulic shovel excavator is analyzed through the D-H method. The shovel working device with the bucket capacity of 36m3 is optimized. The determination of the objective function, variables and constraints are described in detail. The position of optimized shovel is achieved. Also Bucket trajectory and envelope drawing are designed. These are carried on the analysis and comparison. Optimum design is proved rationality.<!--stripped--><!--stripped--></font></font></font></p> D-H method, Face-shovel excavator, Genetic algorithm, Optimum design 2191 2197 http://ase.iust.ac.ir/browse.php?a_code=A-10-63-124&slc_lang=fa&sid=1 M.
