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. (2012) Trans Tech Publications

Mathematical models of structural optimization were established for the cam wave generator
then a conceptual model
by integrally taking its static and dynamic performance into consideration
which satisfied the model acted by four concentrated forces
while the dynamic optimum design was carried out. The topology optimization of the cam wave generator was performed based on artificial material density method
was obtained. And the size optimization of the cam wave generator was also executed based on the zero-order method in software Ansys after setting up its parameterized model. The optimized results indicate that its final volume declines to 1284.217mm3 from its 1397.830mm3
which reduced by 42.18% than the original volume of cam (2221.224mm3). Simultaneously
the static analysis and modal analysis were implemented
and the results show that the static and dynamic performance complies with the design requirements
proving that the results of dynamic optimum design are reasonable. The optimized results in paper are realizable in engineering. And the study method provides not only a reference to decreasing design mass and lowering inertia of the cam wave generator
but also an important basis of lightweight design of harmonic gear drive. 2011 IEEE.

A kind of precision harmonic gear drive in the focusing mechanism of space camera is studied
which adopt external meshing complex wave transmission mode. Wave generator is combined with an elliptic cam and a flexible bearing around it. Flexspline is a structure of single wave with the same teeth. The output shaft is supported by a single cross-roller bearing. Ball screws connected the output shaft translate the rotational motion to the linear motion
and drive the focusing mirror repeated moving along the linear guide. The output rigid wheel is connected with absolute encoder to detect displacement of focusing movement. It has the characteristics of big transmission ratio
high precision
compact structure
high efficiency and smooth running etc. According to the practical application of this harmonic gear drive in the space camera
the location relationship between the displacement of focusing structure and the focal plane movement is derived
and the system error is analyzed
its accuracy is tested with the open-loop control method. Experimental results show that transmission ratio of the instrument is 1:70
repeated positional accuracy is 2m
which meet the requirements for use. 2010 SPIE.
