Load simulator based on follow-up moment load

Abstract

The invention discloses a load simulator based on a follow-up moment load, comprising an elastic force application assembly, a framework assembly, a connecting rod assembly and a torque measurement assembly, wherein the elastic force application assembly, the connecting rod assembly and the torque measurement assembly are arranged on the framework assembly. The elastic force application assembly is used for loading pre-applied force with different gradients on a piece to be detected; the framework assembly is used for loading the follow-up moment load on the same platform; the connecting rod assembly is used for realizing force / torque effective transmission; and the torque measurement assembly is used for effectively measuring the loading torque of a piece to be detected and the rotating angle in the connecting rod assembly. The load simulator is load equipment containing a spring assembly, and the torque load requirements with the different gradients of the piece to be detected are achieved through adjusting the pre-tightening force of a spring through a screw lever. If the load spring cannot meet the requirements, the load spring is replaced by a spring with a different rigidity, and the hanging point of a first connecting rod is replaced so as to realize the torque load requirements with the different gradients. Furthermore, the load simulator can be used for detecting the dynamic rigidity and the static rigidity of the output end of the piece to be detected.

Description

technical field [0001] The present invention relates to a load simulator, more particularly, refers to a load simulator based on following moment load. Background technique [0002] The performance test of instruments and equipment under the condition of reverse torque load is a key technology concerned by the industrial field. Its performance under the reverse torque load will greatly affect the stability, reliability, and rapidity of the instrument and equipment under test. [0003] Apply passive force / torque to the tested part in semi-physical simulation experiments, force calibration and other applications to test whether the tested part is qualified. The load simulator has a good mechanical interface and can also test the tension of high-speed precision lathes, reducers, and rolling mills. system, car brake system, etc. [0004] Most of the existing load simulators focus on loading with small torque, single gradient, and positive torque, and rarely see loading with lar...
