The Generalized Modular Design Method of Emergency Rescue Equipment Vehicle

Emergency rescue equipment vehicles (EREV), with the ability that carry a variety of rescue equipment in different rescue scenes, play an important role in emergency rescue field. However, there still exists some issues in existing EREV products, such as small types and quantity, large volume, small loading capacity, low design efficiency and so on, which can not meet the increasingly complex rescue needs. Because of its low cost, high efficiency, strong interchangeability and reliable product performance, the modular design technology is widely used in machine tool manufacturing, toy production, electronic products, aerospace, automobile manufacturing, building construction and other fields. In this paper, a process model of the generalized modular design method for EREV is designed in order to solve the above issues. All structures and functions of modules in a product genealogy are expressed in a matrix form. This generalized modular design method proposed in this paper gives theoretical references to the design issues of other similar construction machinery devices.
