The development of large deployable space structures requires some mechanical problems to be solved. The problems arise due to unique contradictory demands to the systems: the necessity of increasing the dimension and ensuring the working surface accuracy on the one hand, and strong limitation of load-bearing unit masses on the other. A complex approach to the dynamic analysis of such structures based on a package of developed models where each model solves one of the prob-lems on deploy parameters investigation, determination of dynamic characteristics of structure or estimating the strength of the structural elements is presented
