Applying the Principle of mixed V ariables Solve the Problems of Forced Vibration of the calculating Rectangular Plate by Uniform Load ChenYingjie, Fu baolian, Li Gang, Wu Jie ( Yanshan University Qinhuangdao 066004 ) Abstract : In this paper, applying the principle of mixed v ariables solve the problems of forced vibration of the rectangular plate by uniform load , the stable solution of the cantilever plates by uniform load can be worked out. The results by calculating not only it have academic value, but also it can be directly referred in the actual work . Key words: mixed variables, uniform load, forced vibration , stable solution, cantilever plates Introduction Rectangular thin plate s in engineering are ina wide range of applications . With the development of economy, construction of highway traffic and large industrial factory building and high-rise buildings has developed rapidly . In this engineering, forced vibration problem of Rectangular thin plate s are unavoidable .In engineering ,f orced vibration problem has b ecome more and more important . In the past solution , it ish ard to find a simple displacement function to solve the problem with c omplicated boundary conditions .Putt ing into use mixed variables method is just need d isplacement is weak permitted . In advance, displacement nee
