Problems solved by technology
At present, the simulation body with equal stiffness is specially customized according to the proportion of the specimen or the original size. Different specimen stiffness requires different simulation bodies. Not only is it more troublesome to manufacture, but once damaged, it cannot be repaired, and the cost is relatively high.

The invention discloses an adjustable-rigidity simulator, which comprises a dual-cavity cylinder body, a triplet piston, a single-cavity cylinder body, a collided piston, a collided block and a bracket, wherein both the dual-cavity cylinder body and the single-cavity cylinder body are fixedly connected with the bracket; the bracket is fixedly arranged on a working surface; the triplet piston comprises first, second and third piston bodies which are arranged on a piston rod in sequence; the dual-cavity cylinder body is provided with first and second working cavities; the single-cavity cylinder body is provided with a third working cavity; the first and the second piston bodies are matched with the first and the second working cavities respectively; the third piston body and the collided piston are matched tightly with different areas in the third working cavity; the collided block is arranged outside the single-cavity cylinder body, and is connected with the collided piston; and the first, the second and the third working cavities are provided with first, second and third through holes for injecting a working medium respectively. By adjusting the pressure of the working medium, simulation of objects of different rigidities is realized; and the adjustable-rigidity simulator has the advantages of wide simulation measuring range, high repetitiveness, high accuracy, high controllability, simple structure, convenience for operating and low cost.
Description
technical field [0001] The invention relates to an object simulator in the technical field of mechanical environment tests, in particular to an object simulator with adjustable stiffness in collision tests. Background technique [0002] The impact test of moving objects in the technical field of mechanical environmental testing is mainly to assess the impact resistance of the test piece, and to obtain test data from the test to provide data support for the structural optimization of the test piece. [0003] The impact resistance of the test piece refers to the ability of the test piece not to be damaged after being impacted. There are two factors that affect the impact resistance of the test piece, including: the stiffness of the test piece and the stiffness of the object that collides with the test piece. Among them, stiffness refers to the ability of a structure or component to resist deformation, which is measured by the force or moment required to produce a unit strain. ...
