Particle impact noise detection analyzer

Abstract

The invention discloses a particle impact noise detection analyzer, and the analyzer controls an excitation device to carry out vibration, impact and rotation, and enable redundant materials in a detected part to generate a displacement relative to a housing and generate a sound wave signal. The signal is transmitted to a host through a sensor, and the host and solidification software carry out automatic comparison, analysis and judgment of types of redundant materials and generate a test report. The analyzer can judge and analyze whether there are movable redundant materials in small, middle and large aviation, aerospace, electron, weapon and ship equipment or not, and analyzes the types of the redundant materials. The beneficial effects of the invention are that the analyzer achieves the multi-point synchronous testing and modularized combined testing of the size of a platform top, independently distinguishes the signals of all detection points, customizes a movement execution program, achieves the simultaneous inputting of 4-64 detection signals, can be flexibly attached to the irregular curved surface of a non-plane detected part, guarantees that the transmission of signals is not attenuated, and analyzes the number and material of movable redundant materials through combining a database.

Description

technical field [0001] The invention belongs to the technical field of machinery and electronics, and specifically relates to the design and manufacture of data acquisition and control circuits, analog and digital signal processing, the design and manufacture of vibrators and their power amplifiers, the design and manufacture of rotary tables, the design and manufacture of ultrasonic sensors, the design and manufacture of sensor channel extension platforms and signal processing. Writing of control analysis software. Background technique [0002] The same kind: There is no professional particle collision noise detection analyzer for the detection and analysis of packaged device excess in China. Abroad, only the United States has a particle collision noise detector for detecting small packaged electronic devices. [0003] Related: Some components involved in this invention have similar applications in China, but there are special changes in this invention: [0004] 1. Conven...

AI Technical Summary

Problems solved by technology

[0010] There is no particle impact noise detection analyzer equipment in China, which is a blank in the technology market

Foreign particle collision noise detection equipment can only be used for electronic devices with regular planes below 500g, which cannot meet the requirements for the testing and analysis of large and special-shaped components and complete machines in the fields of aviation, aerospace, electronics, ships, weapons, etc.
