The dynamic analysis method and theory of double-tower connected structures is discussed in this paper .Then modal analysis、static and dynamic time-history analysis is researched with the FEM software ANSYS. Through the structure of monomer and comparative study of the structure in different locations, the basic rules of dynamic characteristics and the rules of layout corridor can be achieved. In addition, by symmetric and asymmetric conjoined comparative study, the basic choose rules of structure type can also be achieved.

This paper considers the development of an active vibration regulation (AVR) system on a convertible car equipped with a hydraulic actuation system. Experimental modal analysis is used to identify a model from the measured dynamic response of the car body and the hydraulic actuators. Two different methods are used to design the AVR system in the presence of process and measurement uncertainties, namely optimal feedback regulation and proportional-integralderivative (PID) compensation. With the aim of reducing the amplitude of the first eigenmode of the system considered, the AVR algorithms are digitally implemented and real-time experiments involving a hydro-pulse four poster rig are conducted. The results from these are evaluated and it is shown that the AVR systems achieve a significant vibration reduction in the first eigenmode, which is important for passenger comfort.
