1. The research on the braking stability of the automatic concrete loading mixer is less than that of the handling stability, and it is found that the domestic research on the braking stability of other types of vehicles is also very few. However, due to the side slip and tail flick during the braking process of the automatic loading mixer, it is easy to cause traffic accidents, so the braking process of the whole vehicle is stable The study of sex is also very important.

2.國內(nèi)針對自動上料攪拌車整車制動性能的研究主要有：通過推導多軸車輛直線制動時地面法向反作用力的通用計算公式，提出了一種便于計算機語言實現(xiàn)的直接計算多軸車抱死順序的算法，基于該算法，推導了地面制動力、制動減速度和制動距離的通用計算公式，著重分析自動上料攪拌車在跑偏的前提下。

2. The domestic research on the braking performance of the automatic loading mixer mainly includes: by deriving the general formula for calculating the normal reaction force on the ground when the multi axle vehicle is braked in a straight line, an algorithm for directly calculating the locking sequence of the multi axle vehicle is proposed, and based on the algorithm, the general calculation formulas of the ground braking force, braking deceleration and braking distance are derived This paper focuses on the analysis of the automatic feeding mixer in the premise of deviation.

自動上料攪拌車前軸兩輪先抱死及后軸兩輪先抱死兩種情況下的自動上料攪拌車運動狀態(tài)，得出后軸先抱死時在任何情況下都損害了自動上料攪拌車的行駛方向穩(wěn)定性，而前軸先抱死時只有在嚴重跑偏情況下才影響自動上料攪拌車行駛的方向穩(wěn)定性。

The results show that when the rear axle is locked first, the stability of the driving direction of the automatic feeding mixer will be damaged in any case, while the direction stability of the automatic feeding mixer will be affected only when the front axle is locked first.
