附录 A Lifts optimization design Cars with glass lifts is key to guide gibs problem. Guide gibs function is to make window glass up and down movement, can in vertical, front and back, the or so direction assurance guidance； General use metal, leather, felt or rubber is made. The above test method although considered the guide friction factors, but DuoZhong and all kinds of automobile glass lifts the actual trajectory there are still differences, a lack of corresponding conversion method. Such as xiali, mai hing industrial vehicle glass lifts, its lifting movement track are big radius arc (R1250mm. 2500 mm). Xiali car window of installed in lifting arm brackets, the window in lifting movement, is to use the groove and roll in the bracket the axial clearance, to constantly adjust Angle brackets, in order to adapt to the window glass in the guide groove movement up and down, so the actual working condition and test on the stage of the simulation working condition is showed in the. In order to make the test requirements close to the actual working condition, through the nearly sample comparative experiments, the statistics and analysis, find the suitable correlation coefficient, is the production of all kinds of glass lifts to all kinds of models of the door, that ensure the match door window product performance, also improve the quality of the test bed of practical value. Because arm type glass lifts manufacturing process relatively simple, low cost, at present our country about 80% of the automobile glass lifts the arm type glass lifts. And soft type glass lifts from stability and resistance movement is much better than the former more compact structure, and the installation and layout are more convenient, but at present our country about soft type lifts, there is no formal national standards. Soft shaft type glass lifts in the world of high-grade vehicle especially cars has been used in great quantities, it is a more advanced glass lifts. In recent years the introduction of domestic automobile products, such as the truck, Beijing, nanjing Cherokee and tell YiWeiKe provided by the lifter. At present some domestic auto parts factory has in such as Beijing automobile glass lifts factory, nac accessory tools factory, sichuan car factory accessories factory completed the soft shaft type glass lifts production technology of technological development (introduction), can provide the product localization. With its low value-added production level, can also be used to replace arm type glass lifts. As the car structure layout design, manufacturing cost, manufacturing technology, the requirements of the manual push-pull type window of adjusting mechanism for many still vehicle in use. At present the arm type and manual (mechanical) glass lifts as the main use the type, the gentle type glass lifts is limited to introduce the application of the model, and electricity-powered glass lifts application is less. Electric glass lifts in foreign high-grade car is very normal, due to the application of the complicated structure, and high cost, and domestic small motor performance instability, the products in our country at present is used in automobile products is less. Can foresee, along with the car design, manufacturing level enhancement, electric glass lifts will more and more application in automobile products. Glass lifts the door system of the door is the attachment. Glass lifts is to realize the car door glass doors accessories lifting movement. Through the glass lifts drive glass bracket for up and down movement, thus make the glass door window frame of door along the guide groove or guide for lifting movement. The common glass lifts main has a fork arm type transmission and rope wheel drive two common form. The latter can adapt to the glass in the big curvature of the surface movement and arc. In addition there is a hand control type two kinds of control ways he electric. The door design and layout. Proper selection and arrangement glass lifts is to guarantee the glass lift control light and reliable work of the key. As the door system of moving parts, lifts and body not only of the layout related internal and external board, at the same time also and the door both sides of guide rail and glass of water cut, sealed inside and outside the door, even have a certain correlation and speakers. In the door system especially inside and outside door plank and glass shape after confirmation, need to be in preliminary based on the door system and glass lifts associated parts layout and analysis. At the same time in the leg levelers mathematical model (CAD) before building also need on the door system and the mutual relationship between nt together.this may and related mechanical analysis. 附录 B 升降器优化 汽车用玻璃升降器的关键是导向槽问题。导向槽的功能是使车窗玻璃上下运动时，能在垂直、前后及左右方向上保证导向作用；一般用金属、毛毡或橡胶制成。上述试验方法虽然考虑了导轨摩擦等多种因素，但与各种汽 车用玻璃升降器的实际运动轨迹仍有差异，也缺少相应的换算方法。如夏利、华利车用玻璃升降器，其升降运动轨迹均为大半径圆弧 (R1250mm 2500mm)。夏利车的车窗玻璃安装在举升臂托架上，车窗玻璃在升降运动中，是利用托架内的凹槽与滚轮轴轴向间隙，来不断调整托架角度，以适应车窗玻璃在导向槽内的上下运动，因此实际工况与试验台上模拟的工况是有出入的。为了使试验要求贴近实际工况，通过近百个样件的对比试验，采用统计与分析方法，找到了适宜的相关系数，是生产的各种玻璃升降器能与各种车型的车门门窗匹配，即保证了产品 性能质量， 也提高了试验台的实用价值。 由于臂式玻璃升降器制造工艺相对简单，成本低，目前我国 80左右的汽车玻璃升降器采用臂式玻璃升降器。而柔式玻璃升降器从平稳性、运动阻力来说大大优于前者结构更紧凑，且安装和布置都较为方便，但目前我国关于柔式升降器尚无正式的国家标准。 软轴式玻璃升降器在世界各种中高档车辆特别是轿车上已被大量采用，是一种比较先进的玻璃升降器。近年来国内的引进汽车产品，如重汽斯泰尔、北京切诺基和南京依维柯等均采用这种升降器。目前已在国内一些汽配厂如北京汽车玻璃升降器厂、南汽随车工具厂、四川汽车厂附件厂等完 成了有关软轴式玻璃升降器的生产工艺的技术开发 (引进 )，可提供国产化产品。随着其批量化生产水平的提高，亦可用于替代臂
