Reduced torque ripple for rotational load with high inertia of HY-2A satellite

Zhou Yong,Li Zhengjun,Ma Chao and Wang Xiaoning

Strategic Study of CAE 2014, Volume 16, Issue 3, Pages 43-49

Abstract:

Taking into account attitude stability，microwave scattermeter and microwave radiometer while rotating need to reduce torque ripple. Permanent-magnet motors using vector control technique are used to drive directly both sensors. Restraining cogging torque of motor， eliminating quantization error with fix angle timing，compensating dead time，these are presented. The control system and motor has been simulated by accurate model，results show that the torque ripple is reduced. The orbital attitude speed results are presented to validate this scheme.

Keywords： high inertia torque ripple quantization error dead time accurate model

Instantaneous deflection of light-weight concrete slabs

Behnam VAKHSHOURI, Shami NEJADI

Frontiers of Structural and Civil Engineering 2017, Volume 11, Issue 4, Pages 412-423 doi: 10.1007/s11709-017-0416-8

Abstract: Construction loading before the age of 28 d can have the most significant effects on the slabs, especially for multi-story structures. The changing properties of the young concrete complicate the prediction of serviceability design requirements also. An experimental investigation is performed on four simply supported Light-Weight Concrete (LWC) one-way slabs subjected to immediate loading at 14 d. Effects of aggregate type, loading levels and cracking moment together with the influences of ultimate moment capacity and service moment on the instantaneous deflection of slabs are studied. Comparison of the obtained results with predictions of existing models in the literature shows considerable differences between the recorded and estimated instantaneous deflection of LWC slabs. Based on sensitivity analysis of the effective parameters, a new equation is proposed and verified to predict the instantaneous deflection of LWC slabs subjected to loading at the age of 14 d.
