The gondola is a widely used in curtain wall of high-rise building cleaning and maintenance of special equipment , modern height cleaning job the best , most secure , high- efficiency , multi-function aerial equipment . In China, with the increase of high-rise buildings , the application of the gondola is also more and more widely . Its safety, reliability, economy also put forward higher requirements . However, more by virtue of experience or a rough hand in the design of the gondola completed a comprehensive understanding of the structural stress distribution , resulting in structural design is not reasonable cause material waste and increase in the cost of the potential security risk to use . Therefore, the to the gondola whole as research object , by means of the finite element method analysis of its static and dynamic mechanical properties , gondola design , transformation and provide a scientific basis for rational use of important theoretical and practical values ??. Firstly, the use of the the DH method on the gondola kinematic analysis to derive the equations of motion of the working point , laid the foundation for the determination of the aircraft operating range , and the follow-up study of inertial load calculation . Wipe windows machine work in three dangerous working conditions , in -depth study of the ANSYS finite element analysis hinge degrees of freedom coupled processing unit mixed modeling technology based on the establishment of the CD250 type of composite the folding arm gondola whole finite element analysis model , and a variety of three dangerous working conditions , respectively gondola load combinations under static deformation and stress distribution were analyzed . Made recommendations to improve the design of the aircraft meet the strength and stiffness requirements . The aircraft based on static analysis , modal analysis, five order natural vibration frequency of the machine and the main modes of work various dynamic loads on the machine vibration is further improve the dynamic performance of the machine provides a theoretical basis .
