摘 要
自十九世紀(jì)第一輛汽車(chē)誕生以來(lái)，汽車(chē)工業(yè)經(jīng)歷了100余年的發(fā)展歷程，由于科學(xué)技術(shù)的不斷發(fā)展，使汽車(chē)的各項(xiàng)性能有了很大的提高。
車(chē)輛在行駛過(guò)程中，由于路面的凹凸不平等眾多因素激起汽車(chē)的振動(dòng)。這種由于道路的凹凸不平而引起的沖擊和振動(dòng)，通過(guò)車(chē)輪傳遞到懸架，然后在由懸架傳遞到車(chē)身，從而引起駕駛?cè)藛T及其乘坐人員的振動(dòng)，當(dāng)然也對(duì)貨物形成沖擊。這樣就使車(chē)輛中的人或貨物處于振動(dòng)環(huán)境中，這種振動(dòng)大大的降低了車(chē)輛行駛的平穩(wěn)性，振動(dòng)影響著人的舒適性，工作效率和健康。
本文主要在對(duì)車(chē)輛減振裝置充分的調(diào)查研究基礎(chǔ)上進(jìn)行車(chē)輛減振裝置的特性分析，選擇參數(shù)進(jìn)行設(shè)計(jì)計(jì)算，并結(jié)合實(shí)際，進(jìn)行雙筒充氣液壓減振裝置結(jié)構(gòu)設(shè)計(jì)。最后對(duì)新型減震裝置進(jìn)行分析。雙筒充氣液壓減振裝置提高了減振裝置在低溫條件下的臨界速度，避免了減振裝置在低溫下的“空程性”畸變，使減振裝置始終處于受壓狀態(tài)有效地抑止了減振裝置在低溫環(huán)境下的“噪聲”；指出了提高減振裝置在低溫條件下性能的有效途徑。雙筒充氣液壓減振裝置明顯地降低了減振裝置在低溫試驗(yàn)、泡沫化試驗(yàn)、耐久性試驗(yàn)下的衰減率，有效地改善了車(chē)輛在通過(guò)凹凸不平路面時(shí)的操縱性和舒適性。指出了用充氣插片進(jìn)行充氣的新方法，這種方法操作簡(jiǎn)單，工藝性好，效率較高。

Abstract
Since the nineteenth century first car was born, automobile industry experienced 100 years of development history, due to the development of science and technology, make the car performance has improved a lot.
In the process of vehicle driving road, because the concave and convex inequality numerous factors aroused vibration of the vehicle. This because of the uneven road and shock and vibration, through the wheel to suspension, then transferred by suspension in the body, thus causes the driver and take personnel for goods of vibration, form the impact. This makes the person or goods in vehicle vibration environment, the vibration greatly reduces the cost of the vehicle, vibration influence people's comfort, efficiency and health.
This paper on the vehicle vibration reduction devices full investigation on vehicle vibration characteristic analysis, the choice of the device parameters, and actual design calculation, the double barrel inflatable hydraulic damping device structure design. Finally understand new shock absorber. Dual cylinder filling hydraulic damping device increased damping device in the low temperature condition of critical speed, avoid the damping device in the low temperature "empty" aberration, make cheng is always in the compression damping device effectively suppress the state of reducing vibration device in the low temperature environment "noise", To improve the damping device that under the condition of low temperature performance in effective ways. Dual cylinder filling hydraulic damping device significantly reduces the damping device in the low temperature test, test, durability test next bubble in the attenuation, effectively improve the uneven road vehicles in through the manipulative and comfort. Pointed out the use inflatable inserted on new methods of air, this method is simple, technology, high efficiency.

Key words: vibration; the double barrel inflatable hydraulic damping device; attenuation
