Nonlinear torsional compliance and hysteresis are associated with harmonic drives, their accurate modeling is crucial for improving performance of the control system drive-based devices such as robot joints. In this paper, a new approach taken to model behavior in drives. The proposed derived by flexspline wave generator instead individual behaviors overall drive transmission. loss captured taking into account. validated through numerical simulations subsequently experimental data.
The large diameter pitch bearing was made of steel 42CrMo4 and the laser hardening process used to improve its surface properties. In this paper, a numerical approach which can predict temperature field hardened depth is provided for steel. According simplification raceway structure bearing, finite element model constructed using ABAQUS software. Based on actual parameters, transient thermal analysis accomplished distribution analyzed. determined according proposed range. Laser power,...
In wind turbine systems, bolted connections are frequently subjected to gravitational and centrifugal loads transmitted by the blades during operation. This can lead attenuation of bolt preloading, resulting in loosening or uneven loading, which turn affects service life generator unit. Therefore, study preloading variations is crucial. However, there numerous factors influencing existing techniques struggle precisely assess preloading. paper proposed a evaluation technique based on hammer...
Non-linear system identification is a hot point problem in the field of electrical information and automatically control. Among many analysis methods, Volterra series model has rigorous theory basic, which can approximate any precision, reconstruct non-linear system, so, it been applied into equipment fault diagnosis. But, with improvement memory length degree, high degree kernel will become complex hard to identification, cause reduction even failure. This paper uses kind reproducing...
In the EMC interference environment of mine, we found is white noise and pulse interference.The UWB signal pulses short power spectral density distributed in wide band very low.This article mainly proposes a de-noising method Wavelet transform modulus maxima band, focused on traditional low-pass filter that can only remove outside-band noise.Simulation results show scheme effectively retain singularity based information to achieve obvious reduction
