| Abstract: | According to the theory of dynamic loads identification,the single spot dynamic loads identification model of arbitrary structure can be obtained by the unit impulse method and the linear superimpose theory.Based on this principle,use PATRAN commend language(PCL)to actualize further software development.PATRAN is used as a platform of software development,and a new module is designed for the single spot dynamic loads identification.Importing the correlative parameters by user’s interface,the system computes the loads and displays the time figure on the window of the software.Experimental results show that the system is manipulated simply and intuitively,with strong stability and high accuracy. |
