Abstract With loads on prefabricated bridges becoming more and more heavier, their dynamic behaviors should be paid more attention to. A virtual prototyping model with the object-oriented technology and the mode synthesis method is presented in MATLAB to analyze dynamic behaviors of prefabricated bridges. Using structural characteristics of the bridges properly, substructures can be looked on as objects which can be encapsulated with the mode synthesis method. The compatibility conditions on interfaces, the Lagrange’s equation and Ritz’s variational principle play the role of messages transmitting among objects. Simulation results indicate that the present model can easily study dynamic behaviors of bridges in the same model.

Stereo parking equipment has become an important means to solve the problem of parking difficulties, so it is necessary to study the planning of stereo parking equipment. This paper proposes an evaluation model for parking equipment planning and design, and verifies the feasibility of the model through an example. First, obtain the surface information of the planned area through object-oriented technology, and then complete the design layout of the area that can accommodate the most parking spaces according to the plan information map of the study area. Next, calculate the number of parking spaces required for each building in the area, and the number of available parking spaces within the maximum acceptable time for each building. Finally, compare the two to design the number and location of parking equipment. This method can quickly and accurately obtain the ground plane information map of the study area, while ensuring the capacity of parking spaces to meet the needs of users, it also improves the rationality and suitability of the planning and layout of stereo parking equipment, which can effectively guide the planning and construction of urban parking equipment.

With the larger and more complex of the size and function of software products,choosing an efficient modeling technique for analyzing complicated and ever-changing system plays a vital role.Object-Oriented Petri nets for its unique characteristics which are simple and laconic modeling method and strong mathematical analysis capacity becomes a hot research.In this paper,it explain that the object-oriented technology how to combine with Petri nets.The typical Object-Oriented Petri net modeling steps and analysis methods are expounded. Up-to-date research about OOPN and its main improved models OOCPN, OOAPN and OOTPN are summarized, the pros and cons of each modeling are analyzed.The interrelated topics and the future development about OOPN are also mentioned.
