Software-calculation-based structural component deformation amount and actual deformation amount ratio confirmation method

Abstract

The invention discloses a software-calculation-based structural component deformation amount and actual deformation amount ratio confirmation method. The method comprises the following steps that a deformation amount delta 1 value is calculated theoretically; the actual measurement deformation amount delta 2 is measured; the ratio of the deformation amount I1 is calculated, wherein I1 is equal todelta 2 / delta1; and primary modification is carried out on a bracket, and a ratio I2 is calculated, and the average value of the two ratios is taken as the software-calculation-based structural component deformation amount and actual deformation amount ratio. The method has the beneficial effects that the determined ratio is suitable for other occasions with relatively high rigidity and strengthfor the designed structural components, practical data support is provided for theoretical calculation of deformation amount of the mechanical design, and the defects in rigidity and strength design can be avoided; and the experiment principle is simple and feasible, and the method can be applied to rigidity and strength verification of the structural components in other batch products, and relatively high basic data support is supported for prolonging the service life of the structural components, improving the stability of the equipment and avoiding waste in design.

Description

technical field [0001] The invention relates to the technical field of mechanical design, in particular to a method for confirming the ratio between the deformation amount of a structural member calculated based on software and the actual deformation amount. Background technique [0002] In mechanical design, in many cases, the engineer knows the control range of the deformation of the designed structural part, and also knows how to use the three-dimensional design software to calculate the theoretical deformation value of the structural part through the force analysis function, but the value of the theoretical deformation It does not represent the actual deformation value of the structural member. The difference between the actual amount of deformation and the amount of deformation required by the design has been puzzling many mechanical design engineers. Many non-standard mechanical design products are one-time designs, and there is no such condition as "after the first d...

AI Technical Summary

Problems solved by technology

Many non-standard mechanical design results are one-time designs, and there is no such condition as "after the first design and processing are verified, and those that do not meet the initial requirements of the design are put into use after improving the design"

Once the deformation of the designed structural parts does not meet the design requirements, there will be congenital design defects such as abnormal noise of running parts, potential safety hazards of equipment, and short service life of structural parts.
