[0002] Generally, when designing the structure of a hydraulic press, the conventional method is to first determine several main dimensions based on experience, and then perform detailed calculations and repeated adjustments to achieve appropriate strength and stiffness, and the amount of calculation is very large.
[0003] At the same time, traditionally, when calculating the strength of the main components of a hydraulic machine, a part such as the upper beam is generally simplified into a separate force model for calculation, and the influence of other structures is not considered comprehensively. When other structures are changed, the force of the upper beam It needs to be recalculated and rechecked, and the previous calculation is meaningless, wasting a lot of time and energy

Embodiment Construction
[0030] In order to further understand the inventive content, features and effects of the present invention's method for quickly optimizing the structure design of a hydraulic press, the following examples are listed and described in detail with the accompanying drawings as follows:
[0031] An optimization method for fast structural design of a hydraulic machine according to the present invention comprehensively considers the influence of the main structure of the hydraulic machine, and establishes a related calculation model. When a certain parameter in the structure changes (such as the The distance between the side cylinders or the throat depth in the single-arm structure), the stress value after the change of each structure can be obtained immediately. Specifically include the following steps:
[0032] 1) Determine the main parameters of the hydraulic press;
[0033] The main parameters include: nominal force P, throat depth L (cm), work table B (cm), upper and lower beam...

An optimization method for rapidly conducting the structural design on a hydrostatic press comprises the following steps: determining main parameters of the hydrostatic press; establishing the forced models of main structures of the hydrostatic press; establishing the forced models of the main structures according to the relatedness and the main parameters of the main structures; establishing a calculation table according to the main parameters of the hydrostatic press and the established forced models of the main structures; inputting the main parameters and the sectional parameters of the main structures for calculation; and analyzing the calculation result, and if the result is improper, after the main parameters and the sectional parameters are adjusted renewedly, a new result is calculated immediately. The calculating process is rapid, and all that is needed is to input the parameters, the stress and the deflection value of the hydrostatic press can be obtained. The structural parameters of the hydrostatic press are adjusted conveniently, and can be properly adjusted according to the output result, the result accuracy is high, and the requirement on the strength and the rigidity is met. The optimization method does not simply calculate the stress station of single parts but comprehensively considers the influences of the main structures of the hydrostatic press.
Description
technical field [0001] The invention relates to an optimization method for structural design, in particular to an optimization method for rapid structural design of a hydraulic press, which can calculate the strength and stiffness of main parts of the hydraulic press. Background technique [0002] Generally, when designing the structure of a hydraulic press, the conventional method is to first determine several main dimensions based on experience, and then carry out detailed and calculation and repeated adjustments to achieve appropriate strength and stiffness, which requires a large amount of calculation. [0003] At the same time, traditionally, when calculating the strength of the main components of the hydraulic press, a certain part such as the upper beam is generally simplified into a separate stress model for calculation, and the influence of other structures is not comprehensively considered. When other structures are changed, the force of the upper beam It is necess...
