The static stiffness and dynamic impact strength of the seat frame are simulated and analyzed based on the enterprise standard on seat back stiffness and GB150832006 Test Method of Occupant Protective Device during Luggage Displacement. The force bearing requirement of the locking device of seat back is presented, and a lightweight design of the seat back structure is put forward according to results of the analysis. The results of simulative analysis show that seat mass is reduced effectively on the prerequisite of meeting the requirement of regulations.Key words: Seat。 Light Weight。 Finite element analysis汽車發(fā)動機(jī)點(diǎn)火系統(tǒng)電磁兼容優(yōu)化技術(shù)研究李 旭 吳存學(xué) 何舉剛 蔡 恒 陳立東 翟建鵬 郭迪軍（中國長安汽車股份有限公司）【摘要】在分析汽車發(fā)動機(jī)點(diǎn)火系統(tǒng)電磁干擾產(chǎn)生機(jī)理的基礎(chǔ)之上，對干擾抑制措施進(jìn)行了研究。在所搭建的點(diǎn)火系統(tǒng)電磁兼容試驗(yàn)臺架上，對部分抑制措施進(jìn)行了試驗(yàn)驗(yàn)證。結(jié)果表明，采用阻值較大及阻尼電阻長度較長的火花塞、在點(diǎn)火線圈的初級和次級繞組間加入屏蔽層，以及采用濾波器等可有效提高汽車發(fā)動機(jī)點(diǎn)火系統(tǒng)的電磁兼容性能。主題詞：發(fā)動機(jī) 點(diǎn)火系統(tǒng) 電磁干擾 抑制措施Research on Electromagnetic Compatibility Optimization Technology for Automotive Engine Ignition System Li Xu, Wu Cunxue, He Jugang, Cai Heng, Chen Lidong, Zhai Jianpeng, Guo Dijun (China Changan Automobile Co., Ltd)【Abstract】Based on the analysis of the mechanism which gives rise to the automotive ignition system EMI, EMI suppression method is investigated.
