【摘要】:隨著汽車行業(yè)的不斷發(fā)展,對汽車各項性能的要求也越來越高,懸架作為汽車重要的組成部分,傳遞車輪與車架之間的一切作用力,并通過減振器的彈性元件與阻尼元件衰減不平路面激勵引起的的車身振動,確保車輛的平順性與操縱穩(wěn)定性要求,傳統(tǒng)的液壓減振器會將這部分振動能量轉(zhuǎn)化為液壓油的內(nèi)能與相關(guān)元件的機械能耗散掉,由于節(jié)能減排技術(shù)逐漸成為汽車的重要性能,如何將汽車這部分振動能量回收并加以利用成了人們關(guān)注的焦點。本文研究一款基于滾珠絲杠式饋能減振器,該減振器具有良好的能量回收能力。首先對現(xiàn)有幾種不同結(jié)構(gòu)的饋能減振器的工作原理以及其結(jié)構(gòu)形式進(jìn)行了簡單介紹,并在此基礎(chǔ)上提出一種新型的滾珠絲杠式饋能減振器,對其結(jié)構(gòu)方案以及工作原理進(jìn)行詳盡的闡述。其次對滾珠絲杠式饋能減振器的阻尼特性、能量回收特性進(jìn)行分析。再次通過對滾珠絲杠進(jìn)行AMESim建模,對滾珠絲杠建模并通過仿真分析驗證模型的可用性,再對滾珠絲杠式饋能減振器建模仿真并驗證模型的可靠性以及饋能能力,進(jìn)而搭建滾珠絲杠式饋能懸架模型,并對其進(jìn)行階躍激勵振動試驗與隨機路面振動試驗,通過兩種仿真試驗對饋能懸架的垂直方向的位移以及加速度進(jìn)行分析,證明饋能懸架平順性與傳統(tǒng)懸架相差不大,并在頻域范圍內(nèi)仿真分析懸架的幅頻特性。最后通過ADAMS與AMESim的聯(lián)合仿真的方法對饋能懸架的KC特性仿真分析。即對ADAMS/CAR Package內(nèi)汽車子系統(tǒng)相關(guān)模板進(jìn)行參數(shù)的修改,建立整車仿真模型,通過更改計算機的環(huán)境變量以及相關(guān)軟件的工作目錄等,建立聯(lián)合仿真環(huán)境,并建立聯(lián)合仿真接口,將建立的ADAMS聯(lián)合仿真模型導(dǎo)入AMESim中,并與饋能減振器的AMESim模型組成整車仿真模型,進(jìn)而對滾珠絲杠式饋能懸架的運動學(xué)以及彈性運動學(xué)特性進(jìn)行仿真分析。
[Abstract]:With the continuous development of the automotive industry, the vehicle performance requirements are increasingly high, as an important part of the automobile suspension, all transfer force between the wheels and the frame, and the shock absorber elastic element and damping element attenuation uneven road excitation caused by the vibration, ensure the ride comfort and handling stability of vehicles the traditional hydraulic damper, this part will vibration energy into mechanical energy, internal energy of hydraulic oil and related components fall due to energy saving and emission reduction technology has gradually become an important performance of the car, the car will be how this part of vibration energy recovery and utilization has become the focus of attention. This paper based on a ball screw regenerative damper, the damper has good energy recovery capacity. Firstly, several existing different structures of the Fed working principle of shock absorber and its junction The structure is introduced, and on the basis of a ball screw regenerative damper model can, in detail, the structure of the program and working principle. Secondly ball screw regenerative damper damping characteristics, analyzed the characteristics of energy recovery. Again through the AMESim modeling of ball screw the ball screw, modeling simulation analysis and verify the availability of the model, the ball screw regenerative damper reliability modeling and simulation and verify the model and feedback ability, and then build the ball screw regenerative suspension model, and carries on the step excitation vibration test and random vibration test, vertical direction suspension of feed through two kinds of simulation of displacement and acceleration are analyzed, that energy regenerative suspension ride and traditional suspension suspension had little difference, analyzed and simulated in the frequency domain. The amplitude frequency characteristics of the frame. Finally, the simulation analysis of KC characteristics by means of joint simulation of ADAMS and AMESim can be fed. The suspension of ADAMS/CAR Package in the auto subsystem related template to modify the parameters, establishes the vehicle simulation model, by changing the environment variables and related computer software work directory, the establishment of a joint simulation environment, and the establishment of joint simulation interface, ADAMS co simulation model into the AMESim will be built, and the whole simulation model of AMESim damper model and the composition of feed, simulation analysis and suspension of ball screw feeding kinematics and elastic kinematics characteristics.
