The Research Of The System About Linkage's Movement Analysis And Dynamic Simulation

Mechanism's analysis and imitation is the key content of the mechanism's design, in which the planar linkage's analysis is more than others. To the mechanism who's structure style is fixed, there have many researches, but their synthesis is still need to be researched.This paper describes the theories of planar linkage's movement analysis and visualization simulation, after comparing with several ways of the mechanism's analysis, adopt the mechanism's construction theory based on rod-group and analysis the mechanism's movement, take the Visual Basic's advantage in figure display, adopt Visual Basic 6.0 as the program language, exploit a system of planar linkage's movement analysis and dynamic simulation and imitation. This system can construct mechanism at random, no limitation in the number of the construction, the synthesis is very high; after amend, make the re-circulate, propose the conception of feasibility, resolve the problem that when the mechanism is not accord with the assemble condition the system will make wrong, so to ensure that the mechanism which constructed at random can make dynamic imitation; count and analysis the feasibility of the mechanism in whole period, then register all the information, and make dynamic simulation, and can output any component's curve of displacement, velocity, acceleration and corresponding text information according to the need, it is visualise and view.This system's interface is very beautiful, and its communion ability between people and computer is very good, and also has a good form in dealing with the fault, when manipulate, we can infer form the hint text, so it is not need special knowledge in using it. Using this system, we can optimise and design new mechanism, and make movement simulation, observe the status of the mechanism's movement, forecast the bug of the design and so to improve the design efficiency.The innovations of the paper:1.Set up the mechanism on the basis of rod-group, and can add or amend freely, during the course of dynamic simulation, we can observe the "real" movement of the mechanism, and also the corresponding data and figure be displayed.2.Make analysis on the feasibility of the mechanism's movement, before simulation, count and analyse the mechanism in the backstage, so as to find out in which angel the mechanism accord with the assemble condition and in which angel not, then the pictures showed to the user is the continuous movement, such improve the run efficiency, and make the program's use be more rational and beautiful.
