A shape design problem is studied for a linkage mechanism used for power shovels based on a mathematical optimization method. With the object of investigating the dynamical relationship of the mechanism, the Lagrange equation of motion is derived by adopting the algebraic programming language REDUCE. The design problem to determine the optimal shape of the linkage mechanism is then formulated as a nonlinear optimization problem of the minimax type; i.e., the sum of the respective maximum values of three driving forces is considered as the objective function to be minimized under constraints related to the dynamic of the mechanism. An algorithm combined with simulation and optimization calculation is proposed to solve the problem numerically, and it is ascertained that the shape of the mechanism can be designed rationally by adopting the method proposed here.
