Confirm the method of calculating the ratio of structural member deformation to actual deformation based on software

Abstract

The invention discloses a method for confirming the ratio between the deformation amount of a structural member calculated based on software and the actual deformation amount, comprising the following steps: theoretically calculating the deformation amount Δ 1 value; measure the actual measured deformation Δ 2 ; Calculate the ratio Ι of the amount of deformation 1 =Δ 2 / Δ 1 ; Carry out a rectification to the bracket, and calculate the ratio I 2 , taking the average value of the two ratios is the ratio between the deformation of the structural member calculated based on the software and the actual deformation. The beneficial effects of the present invention are: the determined ratio is suitable for other occasions where the designed structural parts have higher rigidity and strength, provides the support of practical data for the theoretical calculation of mechanical design deformation, and can avoid rigidity and strength. Design defects; the experimental principle is simple and easy to implement, and can be extended to practice checking the rigidity and strength of structural parts in other batch products; in order to improve the service life of structural parts, the stability of equipment, and avoid design waste, it provides a better Basic data support.

Description

technical field [0001] The invention relates to the technical field of mechanical design, in particular to a method for confirming the ratio of the deformation amount to the actual deformation amount calculated based on software. Background technique [0002] In mechanical design, in many cases, engineers know the control range of the deformation of the designed structural parts, and also know how to use the force analysis function of the 3D design software to calculate the theoretical deformation of the structural parts, but the theoretical deformation of the numerical value. It does not represent the actual deformation value of the structural parts. How much is the difference between the actual deformation and the deformation required by the design, this problem has always puzzled many mechanical design engineers. Many non-standard mechanical design products are one-time designs, and there is no such condition as "after the design and processing are verified, those that d...

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.
