Abstract:
Harmonic drive is a new driving method emerged with the development of space
technology that utilizes the elastic deformation wave of a flexspline to achieve
power transmission. The major failure mode of a harmonic drive is the fatigue wear
of gear teeth in flexspline. In order to investigate the fatigue strength of
flexspline during transmission, this paper designs a new contact fatigue testing
system for harmonic drive to simulate the meshing process of flexspline and circular
spline. The finite element model of the testing system is built by ABAQUS, and
a dynamic simulation is conducted to analyze the stress distribution for
critical positions of the model. The stress analysis results are compared with
the simulation results of a simplified structure of harmonic drive.

As well as the development of conventional gas fields, accurate analysis of
shale gas dynamic and shale gas reservoir characteristics and forecasting
capacity is the basis of the scientific development. The average
open-flowcapacity is obtained by the multi-point back pressure method, and
putting it into the empirical productivity formula to obtain the bottom hole
flow pressure under different test gas systems. Getting the fitting of the
horizontal well binomial deliverability equation under the condition of ideal
gas reservoir with those already known. In the fitting formula, the daily
production capacity of gas well is mainly related to the difference of
production pressure and the length of horizontal section. After determining the
length of the horizontal section and the average formation pressure, the shale
gas production capacity prediction can be completed by using this formula.
