ANALYSIS OF NONLINEAR RIGIDITY CHARACTERISTICS OF AIR BLOWER COMPRESSOR ELASTIC SUPPORTS

چکیده

Vibrations of rotor systems are largely determined by elastic characteristics supports. In the general case, dependence displacements on force for such supports is nonlinear. This applies to bearing various types. addition bearings, elements also used in systems. They designed change overall stiffness The paper analyzes radial flexible ring dampers For this, two main approaches proposed. first a conventional simulation this problem contact mechanics using finite element method. second an analytical method that can be as alternative expensive numerical calculations. based principle minimum additional energy. A special closed-form variational formulation developed Euler-Bernoulli beam approximation and simplified model normal flanges. It was shown surface tolerances parts have significant effect response ring, which become Tight fit both sides makes it much stiffer, non-tight leads free movement weaker damping its movement. Both methods gave results consistent considered cases. By varying their design parameters, possible adjust from critical modes operation. Keywords: system, support, rigidity, analysis, stress-strain state, interaction, energy

Dynamic Analysis of Axially Beam on Visco - Elastic Foundation with Elastic Supports under Moving Load

For dynamic analyses of railway track structures, the algorithm of solution is very important. For estimating the important problems in the railway tracks such as the effects of rail joints, rail supports, rail modeling in the nearness of bridge and other problems, the models of the axially beam model on the elastic foundation can be utilized. For studying the effects of axially beam on the ela...

Vibration Analysis of an Air Compressor Based on a Hypocycloidal Mechanism: an Experimental Study

In this paper, the experimental vibration analysis of a single cylinder air compressor based on a hypocycloid straight line mechanism (HSM) is investigated. The HSM mechanism uses planetary gears to convert rotational motion to purely linear motion. In the conventional air compressor, the slider- crank mechanism is replaced by the HSM mechanism with appropriate counterweights. The constructed s...
