產(chǎn)品介紹
.橡膠緩沖器的X方向靜剛度（抗壓剛度）大于Y方向靜剛度（抗剪剛度），說(shuō)明橡膠緩沖器Y方向的隔振效果比X方向隔振效果好。.橡膠緩沖器的剪切許用變形大于壓縮許用變形。.橡膠緩沖器受壓后僅發(fā)生彈性變形，但其體積不變或變化很小。.振動(dòng)壓路機(jī)振動(dòng)輪的工作頻率與振動(dòng)壓路機(jī)減振系統(tǒng)的固有頻率的比值在大于的情況下，橡膠緩沖器才起到隔振的作用，橡膠緩沖器的剛度越低，隔振效果越好。.橡膠緩沖器對(duì)脈沖信號(hào)的加速度傳遞率隨著靜載荷的增加而增大，其對(duì)高頻帶脈沖信號(hào)隔振能力較好，橡膠緩沖器對(duì)脈沖信號(hào)加速度傳遞率變化范圍12%-28%。.在無(wú)載荷的情況下，橡膠緩沖器對(duì)正弦信號(hào)的加速度傳遞率比對(duì)脈沖信號(hào)的加速度傳遞率低，說(shuō)明橡膠緩沖器對(duì)正弦信號(hào)的隔振能力相對(duì)較強(qiáng)。
計(jì)算結(jié)果表明,采用ENIDINE提出的優(yōu)化設(shè)計(jì)方法設(shè)計(jì)的緩沖器,不但曲軸的扭轉(zhuǎn)振動(dòng)特性得到改善,曲軸帶輪的振動(dòng)也得到很好控制。ENIDINE針對(duì)國(guó)內(nèi)外對(duì)緩沖器異響的分類進(jìn)行總結(jié),將緩沖器異響分為四大類:氣液作用異響、摩擦和撞擊異響、零部件共振異響和機(jī)械干涉異響。ENIDINE針對(duì)以上各個(gè)可能的原因進(jìn)行分析并提出相應(yīng)對(duì)策,以達(dá)到改善車輛的行駛平順性和乘坐舒適性的目的。緩沖器在汽車懸架系統(tǒng)中是一個(gè)重要部件,它可衰減振動(dòng)和改善汽車行駛平順性和舒適性。在現(xiàn)代汽車上都普遍采用緩沖器,薩克斯公司開(kāi)發(fā)了很多緩沖器,適用于汽車的不同用途。通過(guò)對(duì)夏利轎車后緩沖器拉、壓過(guò)程中節(jié)流閥的作用的分析，ENIDINE建立了該緩沖器工作過(guò)程的物理模型。
研究結(jié)果表明,兩種夾持方式的測(cè)試結(jié)果對(duì)判定緩沖器外性能可以通用,而且還能夠從不同方面反映出緩沖器內(nèi)部的動(dòng)態(tài)性能。用計(jì)算機(jī)檢測(cè)技術(shù)對(duì)液壓緩沖器試驗(yàn)臺(tái)進(jìn)行了改造,ENIDINE介紹了檢測(cè)系統(tǒng)的組成和原理,用軟件技術(shù)確定緩沖器振動(dòng)頻率并對(duì)機(jī)構(gòu)運(yùn)動(dòng)誤差進(jìn)行補(bǔ)償。目前我國(guó)出口至海外的軌道車輛日益增多,出口國(guó)家多為亞、非、拉等第三世界國(guó)家。這些國(guó)家多存在鐵路年久失修,路況惡劣,車輛維修維護(hù)不及時(shí)的情況,與國(guó)內(nèi)相比較差距較大。而線路條件差會(huì)給車輛各系統(tǒng)部件的振動(dòng)特別是轉(zhuǎn)向架服役環(huán)境造成很大的影響。這種情況就要求我們?cè)O(shè)計(jì)車輛時(shí)根據(jù)線路特點(diǎn)采取ENIDINE針對(duì)性的措施。ENIDINEENIDINE針對(duì)某出口鐵道車輛油壓緩沖器漏油故障情況,從緩沖器內(nèi)部結(jié)構(gòu)所決定的特性入手進(jìn)行了分析,ENIDINE提出了避免緩沖器漏油的建議。
Then, the dynamic equation is simulated and analyzed by the Simulink component of MATLAB. The results show that the buffer has a good effect on flutter suppression. After that, ENIDINE put forward the control algorithm of MRF buffer based on BP network PID control. Using the on-line learning ability of BP network, the PID control parameters are optimized and self adjusted on-line, which makes the control system have strong adaptive ability and robustness. Because of the advantages of simple structure and low manufacturing cost, the press in rubber torsional buffer is widely installed in the front of the engine crankshaft, which plays a role in reducing the torsional vibration of the crankshaft. ENIDINE studies the performance of rubber torsional buffer, mainly including resonance frequency performance and assembly performance. Enidinenidine analyzes the measures to improve the torsional vibration of the shafting, and focuses on ENIDINE to elaborate the vibration reduction principle and design steps of the torsional buffer. The torsional vibration model of the crankshaft shafting is established by using lexcite-designerenidine. Taking an in-line three cylinder engine as an example, the calculated value of excite-designer matching of the torsional buffer is compared with the test value of Pak matching, The validity of the method of rubber torsional buffer matching by excite designer software is verified.
