【摘要】：現(xiàn)階段我國汽車產(chǎn)銷量高速增長,尤其是A級乘用車成為了人們大量使用的代步交通工具。同時,人們也越來越關(guān)注它的乘坐舒適性。動力總成懸置系統(tǒng)作為整車關(guān)鍵的減振子系統(tǒng),如何減少振動傳遞,從而減少對乘員乘坐舒適性的影響一直是懸置系統(tǒng)匹配設(shè)計的關(guān)鍵。懸置系統(tǒng)的優(yōu)良匹配關(guān)系到整車的NVH性能,甚至能夠影響消費者的購買意愿。經(jīng)過良好匹配的動力總成懸置系統(tǒng),不但能夠有效地降低振動和噪聲,還能夠很好的保護(hù)動力總成,從而提高整車的可靠性品質(zhì)。所以,懸置系統(tǒng)的匹配研究具有重要的意義。本文的主要研究內(nèi)容如下:(1)從介紹懸置系統(tǒng)的隔振原理及目前國內(nèi)外研究現(xiàn)狀開始,提出懸置系統(tǒng)匹配研究具有重要意義。開展懸置系統(tǒng)力學(xué)模型分析,作為理論分析的基礎(chǔ)。介紹懸置系統(tǒng)匹配所需要的不同參數(shù)及參數(shù)獲取方式,闡述懸置系統(tǒng)慣性參數(shù)3D和實物不同方式的參數(shù)獲取方法。通過ADAMS三維動力學(xué)模型的初步驗證,分析出本文車型懸置系統(tǒng)優(yōu)化前存在的不足。(2)通過對懸置系統(tǒng)的布置理論分析引出系統(tǒng)匹配設(shè)計時常用的能量解耦方法,進(jìn)行懸置系統(tǒng)剛度曲線設(shè)定介紹,制定出本文A級乘用車懸置系統(tǒng)開發(fā)的運動控制目標(biāo)和模態(tài)解耦目標(biāo)。通過仿真繼續(xù)優(yōu)化得到最優(yōu)狀態(tài)的懸置剛度,并進(jìn)行懸置剛度曲線的設(shè)計,使常規(guī)工況能起到較好的隔振效果,極限工況能夠控制動力總成的位移等要求。(3)通過懸置系統(tǒng)臺架試驗和實車試驗進(jìn)行分析評價,實驗結(jié)果與仿真分析結(jié)果接近,滿足開發(fā)目標(biāo)要求。同時,提出了適用于A級乘用車懸置系統(tǒng)的主觀評價及評分方法。通過進(jìn)行實車臺架試驗、整車隔振試驗,得出客觀分析數(shù)據(jù),在客觀試驗的同時,開展了實車的主觀評價,從主客觀角度驗證了整套開發(fā)匹配流程的合理性。
[Abstract]:At present, automobile production and sales are increasing rapidly in our country, especially class A passenger car has become a popular transportation vehicle. At the same time, people also pay more and more attention to its ride comfort. As the key damping subsystem of the whole vehicle, how to reduce the vibration transmission and reduce the influence on the ride comfort of the occupant is the key to the matching design of the mount system. The excellent matching of the mount system is related to the NVH performance of the whole vehicle, and can even affect the consumer's purchase intention. After a well-matched powertrain mount system, not only the vibration and noise can be effectively reduced, but also the power assembly can be protected well, thus improving the reliability and quality of the whole vehicle. Therefore, it is of great significance to study the matching of mount system. The main contents of this paper are as follows: (1) starting from the introduction of the isolation principle of the mount system and the current research situation at home and abroad, it is of great significance to study the matching of the mount system. The mechanical model analysis of mount system is carried out as the basis of theoretical analysis. This paper introduces the different parameters and the methods of obtaining the parameters needed for the matching of the mount system, and expounds the methods of obtaining the parameters of the mounting system in different ways, which are 3D of inertia parameters and different ways of the physical objects. Through the preliminary verification of ADAMS three-dimensional dynamic model, the shortcomings before optimization of vehicle mount system are analyzed. (2) the energy decoupling method commonly used in the system matching design is derived by analyzing the layout theory of the mounting system. The stiffness curve of the mounting system is introduced, and the motion control target and modal decoupling target of the A class passenger vehicle mounting system are worked out in this paper. The optimal mounting stiffness is obtained by simulation, and the mounting stiffness curve is designed to make the vibration isolation effect better under normal working conditions. The limit working conditions can control the displacement of the power assembly. (3) the test results are close to the simulation results and meet the requirements of the development goal. (3) through the test of mounting system and the actual vehicle test, the experimental results are close to the results of simulation analysis. At the same time, a subjective evaluation and scoring method for A-class passenger car mounting system is proposed. Through the actual vehicle bench test, the whole vehicle vibration isolation test, obtains the objective analysis data, in the objective test simultaneously, carried out the actual vehicle subjective evaluation, from the subjective and objective angle has verified the entire development matching flow rationality.
