Abstract
Japan was one of the leading nations of the technology developed by comparing and adjusting design which solves the problem in adjustment by designers together. Currently, mechatronics products are accounted for manufacturing market in the world. Functional failure are occurring and increasing by the difficulty of the software with the rapid complication of product function. Since the comparing and adjusting design method based on existing way is failing to keep pace with sophisticated features, in brief the occurrence of rework is the cause at downstream of the design process. Therefore, conceptual design in the upstream stage is important, the authors improve the efficiency of the conceptual design by proposal of integrated physical simulation method using SysML, Problem Frame, and Modelica. Integrated physical simulation method is constituted by six steps, as follows: (1) representation of the requirement diagram, (2) elaboration of the requirements by the problem frame, (3) clarification of the state transition by state machine diagrams, (4) functional design that is based on Modelica, (5) simulation implementation using parametric diagram, (6) evaluation of simulation results. Proposed method can be readily selected conditions which satisfy the requirements by using score sheet to evaluation of the result In this paper, the authors apply proposed method to a design of an intelligent crane and speed up mode, and confirm that proposed method is effectively used in the upstream stage of design Further, the authors understand that the design is efficient m thinking on the assumption four hierarchical structures.
