Simulation Analysis and Experimental Research on Key Connection Structure Strength of Electric Three Wheel Cleaning Vehicle

In order to study the strength of the connection structure between the body frame and the water tank of a cleaning vehicle, the key connection structure of a certain model of electric cleaning vehicle is taken as the research object. Establish a three-dimensional model of the connecting structure, determine the stress characteristics of the cleaning vehicle under two typical working conditions, conduct finite element analysis under different working conditions, and obtain the stress distribution results of the key connecting structure of the cleaning vehicle model. The rationality and accuracy of the stress results obtained from the simulation analysis of the strength of the connecting structure were verified through stress testing experiments. Provide important reference for optimizing the connection structure between the cleaning vehicle frame and the water tank.
