附 录B 外文文献Problems in Measurement of Automotive Wheel Side Slip and Corresponding Counter Measure On the basis of analyzing the generation mechanism of side slip,problems in measurement of side slip,such as great degree of separation,judgment out of truth,etc.,are discussed.It is pointed out that,besides velocity,load,tire pressure,etc.,technical state of side slip testing bench,design of measurement station are also reasons for these problems.In order to resolve these problems,effective measures for ensuring accuracy of measuring results and correct judgment,such as keeping stable measurement condition,developing reasonable standards and application of advanced measurement technology,etc.,are presented.Through the test of the verification of lateral spreads, often finds the over-error of indication, the reason caused there are basically two aspects: one is the mechanical reasons, mainly is sliding board, linkage institutions and back to zero institutions, clearance by increasing wear parts, 2 it is the cause of the electrical testing instruments, or within the sensor electronic devices, zero drift, aging resistance changes caused by damage or element. Adjust the method is as follows:Machinery examinationuse spring tension plan, check the pull and back to zero.The size of the tension and back to the stand or fall of zero depends on two aspects, one is the lubrication system is good or bad, 2 it is back to zero spring aid. The reason for the first on the one hand, the measures should be taken under the skateboard is: check the roller and guide them and clean or replace, check the two pieces of board of middle guide bearing and other bearing and to clean or replace. For the second reasons, the measures should be taken to ensure that is: in zero error is not exceeds the premise cut loose back to zero spring. Due to the reason of tension on the structure, the size and back to the stand or fall of zero is a pair of contradictory, and the tight back to zero spring is back to zero, but pulling force change, the pine back to zero spring is pulling force small, but back to zero is not good. So in the adjustment of the back to zero spring must give consideration to the tension and back to zero 2 a index.check and adjustment of the synchronicityTo use two pieces of BaiFenBiao inspection. Each of the installation board a BaiFenBiao, zero initiative after the completion of the push board (with sensors on one side of the), check the value of two pieces of BaiFenBiao, can read the stand or fall of synchronicity. In the only a piece of BaiFenBiao, will BaiFenBiao into the driven plate, and direct contact with the initiative of the sensor board displacement can be through the measurement instrument to display. The causes of error synchronicity has the following two aspects, on the one hand, the skateboard steering mechanism of bearings between the cause, followed by linkage institutions synchronous lever uniform creates. The form is not identical also, bearing clearance cause of synchronization is generally two pieces of skateboarding is a constant, the length of the board has nothing to do with promoting, and linkage institutions synchronous lever errors is a variable, the error will move along with the skateboard increased. If the driven plate, the value of the larger, driven plate that leverage far away from central shaft, if driven plate, the smaller the driven plate that values from the center axis is close to leverage, adjust any a board, just pay attention to the direction of the adjustment.附 录C外文文献的中文译文汽车车轮侧滑量检测存在问题及对策研究通过对侧滑试验台的检定，往往会发现示值超差，造成的原因基本上有两个方面：一是机械方面的原因，主要是滑动板、联动机构及回零机构机件磨损，间隙增大所致，二是电气方面的原因，测试仪表或传感器内的电子器件老化、零点漂移、阻值变化或元件损坏所致。调整方法如下：1机械方面的检查(1) 用弹簧拉力计，检查拉力和回零情况。拉力的大小和回零的好坏取决于两个方面的原因，一是润滑系统的好坏，二是回零弹簧的松紧。针对第一方面的原因，应采取的措施是：检查滑板下面的滚轮和导轨并加以清洗或更换，检查两块滑板中间的导向轴承及其他轴承并加以清洗或更换。针对第二方面的原因，应采取的措施是：在保证回零误差不超标的前提下调松“回零弹簧”。由于结构上的原因，拉力的大小和回零的好坏是一对矛盾，调紧“回零弹簧”则回零好，但是拉力变大，调松“回零弹簧”则拉力小，但是回零不好。所以在调整“回零弹簧”时一定要兼顾拉力和回零两个指标。(2) 同步性的检查与调整用两块百分表检查。每块滑板各安装一个百分表，调零完成后推主动板（装有传感器的一侧），检查两块百分表的示值，就可读取同步性的好坏。在只有一块百分表时，将百分表装在从动板上，与传感器直接相联的主动板位移量可通过检测仪表来显示。同步性误差产生的原因有以下两个方面，一方面是滑板导向机构的轴承间隙造成的，其次是联动机构同步杠杆不等距造成的。其表现形式也不相同，轴承间隙造成的不同步一般是两块滑板相差一个常数，跟滑板推动的长度无关，而联动机构同步杠杆造成的误差是一个变数，误差会随着滑板移动的增加而增大。如果从动板的数值较大，说明从动板杠杆距中心轴较远，如果从动板的数值较小，说明从动板杠杆距中心轴较近，调整任意一个滑板的都可以，只是注意调整的方向。
