The evolution process of freight car coupler s in our country in the recent 50 years is reviewed.

回顧了我國(guó)貨車車鉤50年來的演變過程国产精品2022免费无码视频，分析了其現(xiàn)狀国产另类一区二区在线，并通過與美國(guó)貨車車鉤的比較永久免费黄片啊啊啊，展望了我國(guó)貨車車鉤的發(fā)展趨勢(shì)飘花电影院午夜伦天堂。

With the small test sample to simulate the local stress conditions of the coupler knuckles,the fatigue tests are carried out according to the load spectrums of pulling and pressing programs of the freight car coupler s and their simplified spectrums.

用小試樣模擬鉤舌局部區(qū)域應(yīng)力狀態(tài)，分別按貨車車鉤拉欧美黄色网站A、壓程序載荷譜和該譜的簡(jiǎn)化譜進(jìn)行疲勞試驗(yàn)丰满少妇弄高潮了www，所得的疲勞壽命值與現(xiàn)場(chǎng)車鉤運(yùn)用調(diào)查統(tǒng)計(jì)值均相符合；同時(shí)开心色亚洲，對(duì) AAR所推薦的恒幅載荷也進(jìn)行了試樣的疲勞試

By compared maximum coupler force and maximum acceleration of car body with common slack coupler at condition of train starting,braking,emergency braking and releasing,we verified that small slack coupler is better than common slack coupler in dynamics performance.This paper also calculated the train dynamics performance parameter with different buffer and braking system,running in different line and using different operating method.
