摘 要
為了適應(yīng)現(xiàn)代機(jī)械精密化與高速化的發(fā)展趨勢，冷軋管機(jī)主傳動(dòng)系統(tǒng)的動(dòng)平衡技術(shù)成為現(xiàn)代冷軋管機(jī)的關(guān)鍵技術(shù)之一。借鑒曲柄滑塊機(jī)構(gòu)動(dòng)平衡技術(shù)的相關(guān)研究成果，本文針對冷軋管機(jī)主傳動(dòng)系統(tǒng)，研究了其優(yōu)化綜合動(dòng)平衡技術(shù)，主要研究內(nèi)容包括：
(1) 研究了冷軋管機(jī)主傳動(dòng)系統(tǒng)的運(yùn)動(dòng)規(guī)律以及在運(yùn)動(dòng)過程中各構(gòu)件的受力情況，并總結(jié)出軋制力對各構(gòu)件的受力與輸入扭矩影響較小，應(yīng)對主傳動(dòng)系統(tǒng)的慣性載荷進(jìn)行有效地平衡?；诖耍敿?xì)討論了曲柄滑塊機(jī)構(gòu)的動(dòng)平衡理論，以指導(dǎo)具體問題的優(yōu)化設(shè)計(jì)工作，達(dá)到慣性效應(yīng)消減的目的。
(2) 建立了冷軋管機(jī)主傳動(dòng)系統(tǒng)的整機(jī)模型，并導(dǎo)出了該模型主要零部件的相關(guān)尺寸與質(zhì)量屬性，為后續(xù)研究提供原始設(shè)計(jì)參數(shù)。以動(dòng)平衡理論為基礎(chǔ)，建立了滿足約束條件下冷軋管機(jī)主傳動(dòng)系統(tǒng)的綜合動(dòng)平衡數(shù)學(xué)模型。
(3) 從構(gòu)建的目標(biāo)函數(shù)可知，綜合動(dòng)平衡是一個(gè)多目標(biāo)的優(yōu)化問題。本文將多目標(biāo)優(yōu)化處理方法與粒子群算法相結(jié)合，開發(fā)了一套適用于絕大多數(shù)曲柄滑塊機(jī)構(gòu)的可視化動(dòng)平衡優(yōu)化軟件。該款軟件即使在沒有產(chǎn)品虛擬樣機(jī)的情況下，只需輸入真實(shí)產(chǎn)品的原始參數(shù)、添加約束條件、設(shè)置粒子群算法的基本參數(shù)，并且選擇相應(yīng)的優(yōu)化處理方式，即可根據(jù)優(yōu)化問題的不同側(cè)重點(diǎn)實(shí)時(shí)地反饋優(yōu)化結(jié)果。通過可視化界面下的數(shù)據(jù)測試，可驗(yàn)證該優(yōu)化方案的正確性，為實(shí)際應(yīng)用中解決隨時(shí)間變化的動(dòng)態(tài)問題提供了一種新的思路。
(4) 運(yùn)用ADAMS軟件對冷軋管機(jī)主傳動(dòng)系統(tǒng)的虛擬樣機(jī)模型進(jìn)行動(dòng)力學(xué)仿真分析，并通過平衡前后機(jī)構(gòu)的剩余慣性力、運(yùn)動(dòng)副反力以及輸入扭矩三項(xiàng)性能指標(biāo)仿真結(jié)果對比，進(jìn)一步驗(yàn)證了基于多目標(biāo)粒子群算法的動(dòng)平衡優(yōu)化方案的優(yōu)越性，機(jī)構(gòu)的動(dòng)力性能得到了顯著地改善。

Abstract
In order to adapt to the trends for mechanical development of high-speed and high-accuracy, the dynamic balance in main transmission system has become one of the key technologies of modern cold-rolling pilger mill. Based on the related research on the balancing technology of slider-crank mechanism, this article discusses consolidated balance in main transmission system of two-high cold-rolling pilger mill. The main research work includes:
(1) Analyse the motion laws and working conditions in movement about the slider-crank mechanism and conclude that rolling force produces a little effect to working conditions of every component. So the work of balancing the inertia load should be operated. Based on all above, the balancing theory of slider-crank mechanism which is discussed in detail guides the optimization work to specific problems. It achieves the goal of reducing the inertia effects.
(2) Establish integral structure’s model in main transmission system of two-high cold-rolling pilger mill. The related sizes and quality attributes about main components of the model provide the basic parameters for subsequent research. Based on the balancing theory, mathematical model of dynamic balance in main transmission system which meets the constraint conditions is constructed.
(3) It is known from the established objective function that consolidated balance problem is a multi-objective optimization problem. This article integrates multi-objective approach with particle swarm algorithm and develops visualization software which is used for solving the balance problem of most slider-crank mechanism. Even in the cases of no virtual prototyping, it could expand real-time optimization and receive rapid feedback on optimization results by inputting parameters related to the real product, adding constraints, setting the basic parameters of particle swarm algorithm and selecting the optimal treatment. Based on the data testing from visual interface, it could verify the correctness of optimization scheme and provide a new way of solving the dynamic problem with time in practical applications.
(4) Import the multi-body dynamic model of main transmission system and carry out the dynamic analysis simulation. By comparing the simulation results of performance indexes such as inertia force, reaction force and input torque before balance with after balance, further verify the superiority of balance proposal based on multi-objective particle swarm optimization algorithm. The dynamic performances of mechanism in main transmission system have been improved significantly.

Keywords main transmission system; dynamic balance; particle swarm optimization algorithm; multi-objective optimization; dynamic simulation
