摘 要
低壓斷路器常被作為低壓配電支路或終端的開關(guān)使用。長(zhǎng)期以來傳統(tǒng)低壓斷路器產(chǎn)品的設(shè)計(jì)研發(fā)是一個(gè)憑借經(jīng)驗(yàn)的大循環(huán)過程，不僅難以提高產(chǎn)品質(zhì)量，而且耗費(fèi)大量的時(shí)間和金錢。
本課題針對(duì)CW1-3200型低壓框架式斷路器機(jī)構(gòu)系統(tǒng)實(shí)際工作過程中存在機(jī)構(gòu)運(yùn)動(dòng)死點(diǎn)、碰撞類型復(fù)雜以及燃弧現(xiàn)象嚴(yán)重等問題，在實(shí)驗(yàn)數(shù)據(jù)的基礎(chǔ)上運(yùn)用多體系統(tǒng)動(dòng)力學(xué)仿真分析軟件ADAMS研究該機(jī)構(gòu)系統(tǒng)的動(dòng)力學(xué)特性和碰撞問題，通過對(duì)斷路器動(dòng)力系統(tǒng)的優(yōu)化分析得到滿足條件的最優(yōu)值模型。

Abstract
Low-voltage circuit breakers are often used as low-voltage power distribution branches or terminal switches. Traditional design and development process of low-voltage circuit breakers by virtue of experience is a big cycle. Not only it is difficult to improve production quality, but also a lot of time and money is spent.
The ACB system has dead bodies, complex collision types, and serious arc phenomenon during practical movement. To solve these problems, ADAMS software was used to calculate and analyze the dynamics characteristics and contact problems based on experimental data, and the optimum value model of meeting specified conditions was obtained by optimizing the power system.
The main contents of this thesis:
1. UG and ADAMS software were used to complete CW1-3200 Low Voltage ACB solid modeling and dynamics modeling.
2. Finite element model was established by Altair HyperMesh and ABAQUS software, and MNF (Modal Neutral File) was calculated and outputted, which was required by ADAMS/Flex. ACB system was rigid and flex simulated and analyzed by ADAMS software, and motion characteristics of body system were obtained. The results showed that dynamics simulation analysis based on flex bodies was more close to theory and reality.
3. The appropriate measurement methods and high sensitivity sensors were adopted to complete the experimental study of ACB, and experimental data was compared with simulation data. The results verified the correctness of simulation data.
4. ADAMS/Optimization was adopted to optimize the power system of ACB. The rotational angular velocity of the moving contact head was as the objective function, design study and optimization of power system were completed. Closing angular velocity of optimized model increased by 15.6%. The model provided technical support in the production improvement and new production development, meanwhile, the arc was avoided.
The dynamics simulation and optimization of ACB system, which were based on experimental and simulation analysis data, provided theoretical and practical support in future production improvement. The actual work results of improved production showed that the research method not only could improve safety and reliability of ACB, but heightened service life.
Key words ACB, dynamics analysis, experimental verification, optimization
