Based on the analysis of some accidents, it is shown that although there are many reasons for traffic accidents, pavement skid resistance, also called friction coefficient, has a great impact on the probability of traffic accidents during driving and braking. Based on the general arrangement of road?lateral?force?coefficient?test?vehicle, the goal of the design is two-wheeled-type road lateral force coefficient test vehicle. After theoretical analysis, comparing the existing technology at home and abroad, carrying out field trips and independent design, the author completes general design of the test vehicle. This test vehicle can detect the road conditions in a safe, reliable, fast and efficient way, which basically meets the needs of road detection. This road lateral force coefficient test vehicle overall can be divided into two parts, namely machinery part and electrical part. With high technology and technological standards of production, it can quickly and efficiently test whether the road skid-resistance is good or bad to guarantee the quality of road and the security of vehicles. In the design process, the author combines the advantages of three-dim
