The long-term working environment of emergency vehicles is affected by many factors, and the emergency environment for various types of emergency vehicles is very different. Here, subdivision is made, and the vertical water supply and drainage emergency environment is the prerequisite environment for exploration. How to study the stability of such emergency vehicles. The first is a brief description of the relevant structure of the vertical water supply, sewerage and rescue vehicle . This type of emergency vehicle is equipped with a large number of specialized functional components based on the chassis of the vehicle, and has a special operation vehicle with a quick and large drainage function. The second is the significance of stability research. In this type of vehicle, the working length when the telescopic tube is fully extended can reach up to ten meters. Mechanically, it will produce a long theoretical tilting force, and the center of gravity of the entire vehicle will also have a large offset, so the entire vehicle will be carried out. The research and analysis of stability have practical significance for the safe and efficient work of emergency vehicles. The third is the law of stability research. The key components of the vertical water supply and sewerage emergency vehicle are lift, swing, and luffing mechanism. Using traditional stability calculation methods, the calculation of these complex structural components is cumbersome and computationally difficult. Compared with the traditional design method, the relevant theory method of simulation experiments under the limit work was used to analyze the stability of the vehicle. The establishment of a simulation experiment platform makes the stability analysis and experimental analysis of the actual work of emergency vehicles more flexible and efficient. The fourth is to study the stability classification. The research on the stability of vertical water supply and sewer rescue vehicles falls into two categories. One is the stability under the non-working normal state, that is, the contraction of each moving mechanism and the withdrawal of the hydraulic legs, taking into account the limit situation that the entire vehicle is fully supported by the tire. One type is working normal stability, that is, under the action of the hydraulic outriggers, sliding and rotating mechanisms, the rear body will leave the ground limit. Because of the operating characteristics and vehicle body design characteristics of the emergency rescue vehicle in the vertical water supply and drainage field, the design emphasizes the enhancement of the relevant stability performance. However, for other professional vehicle types of emergency rescue vehicles, it cannot be generalized, and it is not necessary to focus on the study, but understand the vehicle model. The required advantage is the basis that every research designer must do.
