Balance shafts are often used to improve the engine vibration characteristics of three-cylinder engines. The balance damping gear with a ring is an important part connecting crankshaft and shaft transmission. stiffness unbalance have influence on its suppression performance, but coupled unbalanced unknown. In this paper, multi-body dynamic bending–torsional coupling model transmission system co...
In this paper, the optimal placement and sizing of capacitors for compensation reactive power unbalance in medium voltage distribution networks with unbalanced loads is proposed. The proposed capacitor allocation reduces losses caused by demand unbalance. powers are calculated IEEE STD 1459-2010, presented real values electrical magnitudes three-phase systems. results obtained from method compa...
HSC (High Speed Cutting) milling is one of the most common production processes in tool-making and mold-making industries. One aim current investigations a better understanding dynamics tool shank with high slenderness. Often revolution speed higher than lowest eigenfrequencies shank, so that resonance can appear during run-up or run-out. The focus will be placed on influence an unbalance. Star...
For the assembly of a multi-stage rotor, such as an aero-engine or gas turbine, parts need to be assembled optimally avoid excessive unbalance. We propose method optimize unbalance rotor during assembly. First, we developed error propagation model for rotor. The alignment process and distribution screw holes adjacent rotors was considered first time. Secondly, new datum optimization ensure cons...
BACKGROUND In acute coronary syndrome (ACS), inflammation and redox response are associated with increased residual platelet reactivity (RPR) on clopidogrel therapy. We investigated whether clopidogrel interaction affects platelet function and modulates factors related to inflammation and oxidation in ACS patients differently responding to clopidogrel. MATERIAL AND METHODS Platelet aggregatio...
Abstract. The unbalance-induced vibration of a high-speed rotor directly affects the manufacturing accuracy. To effectively suppress this undesired and avoid complicated process using trial weights during balancing adjustment, modal-based method for without is proposed. First, matrix sweep operation employed to acquire unbalance equivalent plane (EP). Next, concentration methods, vector feedbac...
2 3 The bicycle without a rider balances perfectly well. With a novice rider, it will fall. This is because the novice has the wrong intuitions about balancing and freezes the position of the bicycle so that its own corrective mechanism cannot work freely. Thus learning to ride does not mean learning to balance, it means learning not to unbalance, learning not to interfere.
