轎車盤式制動(dòng)器設(shè)計(jì)及優(yōu)化畢業(yè)設(shè)計(jì)論文

1、I轎車盤式制動(dòng)器設(shè)計(jì)及優(yōu)化轎車盤式制動(dòng)器設(shè)計(jì)及優(yōu)化摘要盤式制動(dòng)器主要用于行車制動(dòng)，其制動(dòng)效能穩(wěn)定，在汽車中得到廣泛的應(yīng)用。首先通過(guò)了解制動(dòng)器的設(shè)計(jì)要求，對(duì)盤式制動(dòng)器進(jìn)行初始設(shè)計(jì)；然后再對(duì)盤式制動(dòng)器進(jìn)行優(yōu)化設(shè)計(jì)。本設(shè)計(jì)通過(guò)對(duì)摩擦片的中心圓半徑、摩擦片直徑、制動(dòng)盤的直徑、活塞直徑、制動(dòng)盤厚度、油缸內(nèi)的油壓等參數(shù)的優(yōu)化設(shè)計(jì)，以制動(dòng)時(shí)間、制動(dòng)盤的厚度、制動(dòng)盤的溫升作為優(yōu)化設(shè)計(jì)目標(biāo)，建立盤式制動(dòng)器的優(yōu)化設(shè)計(jì)數(shù)學(xué)模型。選用合理的優(yōu)化設(shè)計(jì)方法，編寫M

2、ATALB程序，通過(guò)優(yōu)化程序的運(yùn)行，得到最終優(yōu)化結(jié)果，從而得出盤式制動(dòng)器較合理的尺寸。關(guān)鍵詞：盤式制動(dòng)器；轎車；設(shè)計(jì)；優(yōu)化III目錄前言...........................................................................................................................11汽車制動(dòng)系概述....................
