Wave theory modeling of vehicle vibration and its frequency response analysis of helical spring suspension 螺旋彈簧懸架車輛振動的波動理論建模及頻響分析
In order to simulate the exact boundary condition , the simple model of air spring suspension was set up 為了準(zhǔn)確模擬該模型的邊界條件,增加了空氣彈簧懸架的簡化模型。
The acceleration response of the sprung mass for the quarter vehicle model the suspension system under periodical excitation and certain road uneven random excitations were discussed 為了反映實車狀況,著重討論了在調(diào)和激振和隨機(jī)路面激振下變剛度彈簧懸架簧載質(zhì)量的動態(tài)相應(yīng)特性。
In the chapter 3 , algor feas ( also called super sap ) , a commercial fem software is introduced ; several . problems in building the finite element model of a auto frame is researched ; taking advantages of fem and mathematic programming , a strength analysis method of the frame of a series multi - spindle hydropneumatic suspension automobile is proposed ; taking the structure and load characteristic of a missile ' s frame into account , the static , eigenvalue and response analysis have been made by using super sap91 第三章簡要介紹了大型有限元軟件sap91 ;對車架有限元建模及分析中的若干問題進(jìn)行了討論;利用有限元法和數(shù)學(xué)規(guī)劃法相結(jié)合,提出了一種串聯(lián)多軸油氣彈簧懸架車輛車架強(qiáng)度分析的方法;針對某導(dǎo)彈發(fā)射車車架的結(jié)構(gòu)和載荷特點,利用sap91軟件對其進(jìn)行靜力分析、特征值分析和動力響應(yīng)分析。
