This article is the study of alternating stress of flexible wheel in harmonic gear drive system. Firstly  then  Finally  according to elasticity theory to theoretically analyze flexible wheel stress  based on the basic principle of sub-structure modal synthesis method  based on the dynamics simulation  use the software of UG  to analyze the alternating stress simulation results of flexible wheel and compare theoretical results and simulation results to come conclusion. The results show that: altering stress simulation results of flexible wheel are coincident with theoretical simulation results  PATRAN and ADAMS to carry out co-simulation  have a deeper understand the stress change trend in the drive process of flexible wheel  lay a foundation for further carrying out dynamics simulation of harmonic gear drive system.

Hinge in mechanical systems exist small clearance and contact deformation  After consideration of flexible components  cause the system to the wear and tear  impact force reduced at the clearance  noise  contact time increased  vibration  contact-impact areas expand and clearance also caused disturbance of the rod angular velocity of the linkage. 2011 IEEE.  reliability reduce or even failure[1]. Therefore  the hinge clearance and the impact of flexible components in kinetic models should be considered. In this paper  a nonlinear spring-damper hinge clearance model is considered to establish mechanical system structure of dynamic equations[46]  through a four-bar linkage hinge with multi-clearance rotation of ADAMS dynamic simulation for dynamics simulation study. Simulation results show that hinge clearance and link flexible in Four-link mechanism dynamics have a great impact on performance: connection with the clearance lead to pin holes to produce a series of collisions  and a larger initial impact force

Modulation transfer function resulting from random vibration was analyzed. To conclude that the effect of angular displacement was the major factor. Allowable MTF degradation was represented  and 34dB reduction was achieved at frequency of 100HZ. With the help of MSC.ADAMS simulation software  and convert allowable MTF degradation into stable system design parameters  simulated curve proves correct for isolator  which can guide perfect design for stabilization system. Based on the spatial mechanism and translational principle of parallelogram  and the irrotational displacement mechanism was tested by optical method  an irrotational displacement isolator was developed. It can meet the requirements of irrotational displacement and damp. An instance was given  coupled angle is less than 8?  it can satisfy the demand of aerial imaging. (2011) Trans Tech Publications.
