Abstract

The invention discloses a dynamic and static characteristic recognition device of a motion device. The dynamic and static characteristic recognition device comprises a built-in part and an external part. The built-in part is mainly responsible for acquisition, conditioning and transmission of input signals and comprises an acquisition module, an isolation module, a modulation module, a sampling and holding module, an A/D conversion module, a straight-through conversion module and a signal transmission module. The external part is mainly responsible for collecting output signals and receiving and processing the signals, and comprises a multi-sensor module, a signal receiving module and a processing module. The device can acquire dynamic and static responses of a plurality of motion devicesin real time under the condition of not influencing or damaging original transmission characteristics, can realize processing of multi-sensor signals of one group of multi-dimensional motion devices or the plurality of motion devices under single input signals or multi-input signals, and can recognize the dynamic and static characteristics of the plurality of motion devices under different workingconditions, so the electromechanical static characteristics of the motion devices and the difference among different motion devices are disclosed.

Description

technical field [0001] The invention relates to the research field of dynamic and static characteristics of a moving device, in particular to a multi-dynamic and static characteristic identification device for studying a moving device under single-input or multi-input signals. Background technique [0002] The dynamic and static characteristics of the system refer to the nature, characteristics and functions of the system in the dynamic and static process. The study of the dynamic and static characteristics of the mechanism is very important to the improvement of the quality and performance of the mechanism. However, in the actual process, for the study of the characteristics of the mechanism, typical input signals are often used, that is, the unit step function, the unit ramp function, the unit pulse function and the sine function. , to study the dynamic performance of the mechanism, the input signals of the mechanism and each component link in the actual control system are...
