Engine suspension triaxial stiffness detection structure

Abstract

The invention provides an engine suspension triaxial stiffness detection structure. The structure comprises an X-direction platform, a Y-direction platform and a Z-direction auxiliary portal frame; anX-direction slide rail is fixed on the X-direction platform; the X-direction slide rail is matched with an X-direction sliding block; the X-direction sliding block is fixed at the bottom of a middleplatform; a Y-direction slide rail is fixed to the top of the middle platform; the Y-direction slide rail is matched with a sliding block at the bottom of the Y-direction platform; a sample supportingseat is arranged at the upper part of the Y-direction platform; a supporting plate at a side portion of the Y-direction platform is provided with an X-direction limiting device; and the Z-direction auxiliary portal frame is provided with a vertical moving device. According to the engine suspension triaxial stiffness detection structure of the invention, restraining and limiting at a Z direction are performed through the Z-direction auxiliary portal frame, and at the same time, and fixed Z-direction loading is not affected by other directions; low-friction linear guiding rails are adopted as the X-direction slide rail and the Y-direction slide rail so as to realize decoupling, and therefore, performance testing will not be interfered and affected. The engine suspension triaxial stiffness detection structure is low in price and can be afforded by most companies.

Description

technical field [0001] The invention relates to an engine detection device, in particular to an engine mount triaxial rigidity detection structure. Background technique [0002] The engine mount is the key elastic component of the engine vibration damping system. Its main function is to eliminate the excitation vibration and noise during the ignition of the engine. Because the engine has 6 degrees of freedom during the motion, it needs to be constrained and limited by the engine mount. position, engine mount triaxial test tooling, the purpose of which is to test the 6-DOF performance of the engine mount. MTS in the United States has such special equipment for 6-DOF performance, but its price is about 7 million yuan, and many companies unbearable. [0003] Therefore, it is an urgent need to design a new type of triaxial test fixture with low price and high test accuracy. Contents of the invention [0004] The object of the present invention is to provide a three-axial rig...
