Adjustable tension and compression rigidity simulator and mechanical drive link

Abstract

The invention discloses an adjustable tension and compression rigidity simulator and a mechanical drive link; the adjustable tension and compression rigidity simulator comprises the following elements: two elastic plates; a connecting assembly enabling the two elastic plates to be parallelly arranged and fixedly connected; lug assemblies used for being respectively arranged between the two elastic plates. The connecting assembly is connected in the mechanical drive link and used for transmitting the force in the mechanical drive link to the two elastic plates; the two elastic plates receive the force, so a connecting portion between the elastic plates and the connecting assembly and connecting portions between the elastic plates and the two lug assemblies elastically deform; elastic deformation amount of the elastic plates receiving the force can be changed through adjusting the positions of the two lug assemblies arranged on the two elastic plates. By employing the structure, other parts in the mechanical drive link can be designed in rigidity so as to reduce design and processing difficulty of other parts in the mechanical drive link, and design is simple.

Description

technical field [0001] The invention relates to the technical field of mechanical design, in particular to an adjustable tension-compression stiffness simulation device and a mechanical transmission link. Background technique [0002] In the design of electromechanical systems, the stiffness of the mechanical transmission link is an important factor affecting the performance of the system, so the stiffness value of the mechanical transmission link needs to be simulated in the system design. [0003] In the prior art, a pneumatic cylinder type or a fixed structure type simulation device is usually used to simulate the mechanical transmission link. [0004] Using gas as the working medium, its stiffness characteristics are easily affected by temperature; under the action of dynamic load, the temperature of the gas rises significantly, the working stability of the device is poor, and the gas sealing is difficult. [0005] The fixed-structure stiffness simulation device can mee...
