The Design Method of Vibrating Screen Dynamic Design

With the further expansion of production, learning and research momentum, many domestic universities and research institutions joint domestic famous heavy industry enterprises for cooperation and development of mining machinery for many projects. Our company carried out the jointly vibrating screen dynamic design study with the other companies.

The finite element method and experimental modal analysis is the basic methods of structural dynamic design. Structural dynamic design of the basic process is as follows: According to the design task, product preliminary design, drawing frequencies and mode shapes of the structure diagram of the preliminary design until you meet the requirements. Secondly, based on theoretical calculations or experience estimated structural load by the experience of the assumption that the system damping, the dynamic response of the finite element model of computing systems above, including displacement, velocity, acceleration, deformation and stress, etc., verify meet response criteria. Such does not meet the sensitivity analysis to modify the finite element model, corrected mass matrix and modified stiffness matrix, re-calculation of the structural response, until you meet the requirements.
The theoretical
modeling of structural dynamics analysis is the basic method of the vibrating
screen dynamic design, finite element method for simple structure, vibrating
screen for theoretical modeling can often get satisfactory results. For complex
structures, such as multi-layer sieve, circular vibrating screen, although its
preliminary analysis of the results of large deviation, but still can be used as
an important reference for subsequent modal test response measured in the
arrangement of measuring points, and can also be combined with experimental
modal parameter correction and structural dynamics finite element model of the
vibrating screen to modify. Structural finite element analysis is one of the
important step of vibrating screen dynamic design.

since the vibrating screen equipment birth, over a long period of
development, it has been in continuous improvement and growing range of
screening materials, some wet and the difficulty of screening materials, shaker
difficult role to play, but after a Shanghai Hill Kai machinery Manufacturing
Co., Ltd. technical staff have been efforts, Hill Kai vibrating screen has been
screening all kinds of materials and wet materials dry sieving.

Seiko collection assembly and load commissioning equipment are required
before these equipments are sent out the factory ,and all indicators should be
checked qualified , after these equipments are shipped to the scene, the user
should check the entire machine according to the packing list and equipment
invoices , whether the technical documentation has flaws or not .
