Abstract

The invention provides a six-dimensional mechanical performance testing device and a testing method for physical structural parts, and applies a parallel motion structure to the mechanical performance testing of structural parts to solve the deficiencies in the prior art. The device includes the following components: a control system, a sampling system, and a parallel loading mechanism. According to the actual shape and structure of the physical structural parts to be measured, multiple physical structural parts six-dimensional mechanical performance testing devices can be used in conjunction with each other. The main feature of the test method is to perform multi-dimensional force loading according to the time function of the loading displacement, and analyze the actual stress distribution of the structural parts as a reference for structural design. Through the technical scheme of the invention, more accurate stress-strain distribution data, more accurate location of dangerous parts and more real damage form can be obtained. It is of great significance to the optimization of weapon structure, lightweight, precise design of safety and reliability.

Description

(1) Technical field [0001] The invention relates to a device and method for testing six-dimensional mechanical properties of physical structural parts, belonging to the technical field of mechanical experiments. (2) Background technology [0002] One of the important causes of malfunctions in the operation of weapons is mechanical failure. The strength failure of components is the main factor causing mechanical failure. The main basis for the strength design of the existing parts is the mechanical properties of the material. The data of the mechanical properties of the material is obtained by making the same material into a standard sample and through the mechanical experiment on the sample. The loading forms in the standard mechanical performance experiments are basically simple tension and compression, bending or torsion. [0003] However, the cross-sectional size and structural form of the actual structural parts are very different from the standard samples. Due to the ...
