作者：YU; Bin; TIAN; Feng-chun; HE; Qing-hua; RAN; Jian; LV; Bo; HONG; Xin; LIU; Tao; BI; Yu-tian 刊期：2016年第04期

In this paper, a wavelet packet feature selection method for lung sounds based on optimization is proposed to obtain the best feature set which maximizes the differences between normal lung sounds and abnormal lung sounds （sounds with wheezes or rales）. The proposed method includes two main steps： Firstly, the wav...
Helical angle measurement of worm by a coordinate measuring machine and its uncertainty evaluation

The purpose of the study concerns the measurement of worm＇s helical angle by a coordinate measurement machine inthe ambient industrial environment. The novel measurement method and sampling strategy were described firstly. This methodused the coordinate measurement machine to measure both of the worm gear＇s left an...
Mathematical modeling and characteristics analysis for the nutation gear drive based on error parameters

作者：JI; Wen-tao; YAO; Li-gang; ZHANG; Jun 刊期：2016年第04期

We focused on the mathematical modeling and characteristics analysis for the nutation drive based on error parameters.The crown gear tooth profile equation was introduced according to the national standard double circular arc tooth profile andbased on the equal tooth strength principle. The nutation drive meshing coo...
Translational - torsional coupled model based nonlinear dynamic analysis of an NGW planetary gear train

作者：LIU; Zhen-zhou; ZHANG; Jun; BIAN; Shi-yuan 刊期：2016年第04期

This paper aims to investigate the nonlinear dynamic behaviors of an NGW planetary gear train with multi-clearancesand manufacturing/assembling errors, For this purpose, an analytical translational - torsional coupled dynamic model isdeveloped considering the effects of time-varying stiffness, gear backlashes and com...
