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.

In this paper  a method of measuring the 3-D pose of the remote revolving target such as rocket or missile by using the intersected measuring system with a proper algorithm is described. This passage creates a math model of intersected measuring system with dual - photoelectric theodolite and the formula to calculate the target attitude angles are presented.The measuring precision of this method is analyzed in detail by using the relative error theory  and then it makes optimization design for structure parameters of intersected measuring system with dual - photoelectric theodolite by computer simulation  so different optimization results according to different location of target are obtained  and the system lay-out  measuring principles are also presented. By using this method we may acquire the measuring precision higher than 0.5 if the measuring stations are arranged correctly.
