A Composite Load Simulator Realizing Multidimensional Pure Bending Moment and Tensile Compression

Abstract

The invention discloses a composite load simulator for achieving multidimensional pure bending moment and tensile pressure. The composite load simulator can achieve pure bending moment loading, tensile pressure loading and pure bending moment and tensile pressure composite loading in any direction. The simulator comprises a moving platform, a fixed base and moving branch chains. The moving platform is fixedly connected with a loaded test piece, and the moving branch chains comprise the central moving branch chain and the uniformly-distributed moving branch chains, wherein the uniformly-distributed moving branch chains are of six different structures. The uniformly-distributed moving branch chains of the different structures, the central moving branch chain, the fixed base and the moving platform can form six kinds of different bending moment-tensile pressure composite load simulator structures. The composite load simulator has the advantages that the composite load simulator can achieve multidimensional pure bending moment load output and can output composite loads of the bending moment and the tensile pressure; due to the fact that the branch chains exist, the structure has high bearing rigidity, decoupling can be achieved through output of the tensile pressure and the bending moment, and the composite load simulator is convenient to control, simple to manufacture and convenient to install.

Description

technical field

[0001] The invention relates to a compound load simulator capable of realizing multi-dimensional pure bending moment and tensile pressure, which belongs to the field of robot and machine manufacturing. Background technique

[0002] The load simulator is an experimental device used for semi-physical (experimental) simulation on the ground, which can simulate the impact of the measured object under special environmental loads under laboratory conditions.

[0003] Traditional experimental testing methods often need to place the measured object in the actual working environment for testing and collect relevant data, but the cost is extremely high, and it is relatively difficult to collect real-time data. The use of the load simulator can transform the classic full-physical experiment into a semi-physical predictive experiment under laboratory conditions, so as to obtain various performance parameters of the measured object and provide a basis for further performa...
