Deployable solar arrays play an important role in the realization of various spacecraft missions. Taking flexible as application background, natural characteristics a jointed-panel structure is investigated this paper. Based on energy conservation principle and Rayleigh-Ritz method, analytical approach for obtaining frequencies extracting global mode functions was developed. Considering panel isotropic rectangular plate connection at each hinge joint with additional linear rotational spring,...
Clearance turns up in a large number of engineering structures because the errors during assembling, manufacturing, and wearing. The presence clearance changes normal dynamic response will result low precision short lifetime. parameter identification such nonlinear system is prerequisite to control eliminate effect nonlinearity. In this paper, derivative plot probability density function (DPPDF) for displacement proposed precisely identify value continuous system, subspace (NSI) method...
Clearances existing in artillery mechanism cause the muzzle disturbance and reduce firing accuracy. If parameters of clearance nonlinearity can be identified by taking advantage dynamic information, quantitative relation between established, then clearances such nonlinear system controlled a reasonable range to improve This paper proposed identification method for cantilever beam with reduced from barrel-cradle structure. A modified restoring force surface is identify value time domain,...
In this paper, an analytical dynamic model is proposed for vibration suppression of a multi-span continuous bridge by tuned mass dampers (TMDs). Firstly, the partial differential equations (PDEs) that govern motion and TMDs are obtained, respectively. According to matching conditions boundary conditions, mode shapes derived, orthogonality relations proven. By using their relations, PDEs truncated into ordinary (ODEs) describe entire system. To verify model, natural frequencies solved...
A dynamic model of an L-shaped multi-beam joint structure is presented to investigate the nonlinear behavior system. Firstly, partial differential equations (PDEs) motion for beams, governing tip mass, and their matching conditions boundary are obtained. The natural frequencies global mode shapes linearized system determined, orthogonality relations established. Then, used derive a set ordinary (ODEs) that govern jointed structure. accuracy verified by comparison solved frequency equation...
An analytical dynamic model is presented for a spacecraft with multiple large flexible structures. Based on the partial differential equations (PDEs) of motion solar panel and deployable arm, governing main-body antenna boundary conditions at each end point are used to obtain frequency mode shapes system. Then, ordinary (ODEs) system can be obtained from orthogonality relations shape. The influence frequencies investigated. veering interchanged phenomenon observed variation diameter antenna....
In gun barrel-cradle structure, the presence of clearance usually changes dynamic response muzzle and results in shooting dispersion (under continuous firing condition). The parameter estimation such nonlinear system is prerequisite for establishing quantitative relation between disturbance. this paper, restoring force surface (RFS) method identification through feedback outputs (NIFO) are first combined a simplified structure. With RFS method, value can be obtained by analyzing plot. Then...
