摘要

為了滿足現(xiàn)代汽車懸架提出的各種性能要求,懸架的結(jié)構(gòu)形式一直在不斷地更新和完善,盡管這樣,傳統(tǒng)的被動懸架仍然受到很多限制,主要是難于同時改善在不平路面上高速行駛車輛的穩(wěn)定性和行駛平順性,即使采用優(yōu)化設(shè)計也只能保證懸架在特定的激勵發(fā)生變化后,懸架的性能亦隨之發(fā)生變化,為了克服傳統(tǒng)的被動懸架對汽車性能改善的限制,近年來,汽車工業(yè)中相繼出現(xiàn)了性能更加優(yōu)越的主動懸架和半主動懸架。

Abstract

In order to satisfy the modern automobile suspended frame of the proposed all sorts of performance requirements, suspension structure form has been in constant updates and perfect, despite this, traditional passive suspension still subject to many restrictions, mainly is difficult to improving the uneven pavement on the stability of the vehicle and the art of, even if adopting the optimization design also only guarantee the suspension in particular incentive change, suspension performance also change, in order to overcome the traditional passive suspension for car performance improvement the limit, in recent years, the auto industry in succession in appeared more superior performance active suspension and semi-active suspension

Keywords: car active suspension semi-active suspension production and development direction
