【摘要】：氣彈簧（Gas spring)是一種不同于傳統(tǒng)金屬彈簧的彈性元件，，通過活塞在密封的缸筒內(nèi)壓縮惰性氣體或者油氣混合物，利用缸筒活塞兩側(cè)的壓力差所產(chǎn)生的軸向力來實(shí)現(xiàn)支撐、緩沖、制動、復(fù)位、高度調(diào)節(jié)及角度調(diào)節(jié)等功能，已經(jīng)廣泛用于汽車、航空、醫(yī)療器械、家具、機(jī)械制造等眾多領(lǐng)域。隨著我國工業(yè)的迅速發(fā)展，對氣彈簧產(chǎn)品的性能要求不斷提高。2010年國家標(biāo)準(zhǔn)《GB/T25750-2010可鎖定氣彈簧技術(shù)條件》和《GB/T25751-2010壓縮氣彈簧技術(shù)條件》正式發(fā)布實(shí)施。國家標(biāo)準(zhǔn)中規(guī)定了高低溫環(huán)境下的疲勞試驗(yàn)要求，比此前實(shí)施了十幾年的行業(yè)標(biāo)準(zhǔn)中的高低溫儲存疲勞試驗(yàn)更科學(xué)合理，對產(chǎn)品要求更苛刻。 氣彈簧高低溫疲勞試驗(yàn)是模擬氣彈簧在惡劣環(huán)境下工作的試驗(yàn)方法，是氣彈簧的重要性能指標(biāo)之一。由于原來的行業(yè)標(biāo)準(zhǔn)中沒有相應(yīng)的技術(shù)要求，目前國內(nèi)上還沒有用于氣彈簧的成型檢測設(shè)備，使國家標(biāo)準(zhǔn)的實(shí)施遇到困難。本文對氣彈簧高低溫疲勞試驗(yàn)進(jìn)行了分析，并介紹氣彈簧高低溫疲勞試驗(yàn)機(jī)研發(fā)情況。
[Abstract]:The gas spring (Gas spring) is a kind of elastic element which is different from the traditional metal spring. The piston compresses the inert gas or the mixture of oil and gas in the sealed cylinder, and makes use of the axial force produced by the pressure difference between the two sides of the cylinder piston to realize the support. Cushioning, braking, reset, height adjustment and angle adjustment have been widely used in automotive, aviation, medical equipment, furniture, machinery manufacturing and many other fields. With the rapid development of China's industry, the performance requirements of gas spring products have been continuously improved. In 2010, the national standards "GB/T25750-2010 lockable gas spring technical requirements" and "GB/T25751-2010 compressed gas spring technical conditions" were officially issued and implemented. The requirement of fatigue test in high and low temperature environment is stipulated in national standard, which is more scientific and reasonable than that in industry standard for more than ten years. The high and low temperature fatigue test of gas spring is a test method to simulate the gas spring working in bad environment, and it is one of the important performance indexes of gas spring. Because there is no corresponding technical requirement in the original industry standard, there is no testing equipment for gas spring in our country at present, which makes the implementation of national standard difficult. This paper analyzes the high and low temperature fatigue test of gas spring, and introduces the research and development of gas spring high and low temperature fatigue testing machine.
