附 錄 B 外文文獻 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 examination use 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 synchronicity To 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 錄 C外文文獻的中文譯文 汽車車輪側滑量檢測存在問題及對策研究 通過對側滑試驗臺的檢定，往往會發現示值超差，造成的原因基本上有兩個方面：一是機械方面的原因，主要是滑動板、聯動機構及回零機構機件磨損，間隙增大所致，二是電氣方面的原因，測試儀表或傳感器內的電子器件老化、零點漂移、阻值變化或元件損壞所致。調整方法如下： 1機械方面的檢查 (1) 用彈簧拉力計，檢查拉力和回零情況。 拉力的大小和回零的好壞取決于兩個方面的原因，一是潤滑系統的好壞，二是回零彈簧的松緊。針對第一方面的原因，應 采取的措施是：檢查滑板下面的滾輪和導軌并加以清洗或更換，檢查兩塊滑板中間的導向軸承及其他軸承并加以清洗或更換。針對第二方面的原因，應采取的措施是：在保證回零誤差不超標的前提下調松 “回零彈簧 ”。由于結構上的原因，拉力的大小和回零的好壞是一對矛盾，調緊 “回零彈簧 ”則回零好，但是拉力變大，調松 “回零彈簧 ”則拉力小，但是回零不好。所以在調整 “回零彈簧 ”時一定要兼顧拉力和回零兩個指標。 (2) 同步性的檢查與調整 用兩塊百分表檢查。每塊滑板各安裝一個百分表，調零完成后推主動板（裝有傳感器的一側），檢查兩塊百分表的 示值，就可讀取同步性的好壞。在只有一塊百分表時，將百分表裝在從動板上，與傳感器直接相聯的主動板位移量可通過檢測
