Abstract

The invention discloses a truck smoothness stability simulated analysis method. Simulated analysis is carried out on the phenomenon that the smoothness of a truck of a certain model number is sometimes good and sometimes bad, and the smoothness is not stable. The nonlinear kinetics theory is used in the field of truck smoothness, and the numerical simulation analysis method of the truck smoothness instability phenomenon is established. Simulation results are analyzed, simulation analysis results are displayed in a curve mode, and the smoothness instability phenomenon is expressed visually. The smoothness sudden changing reason is explained, and a corresponding solution and a certain foundation are provided for truck comfort and whole truck performance improving. A parameterized graphical user interface is developed based on a MATLAB developing platform, a user only needs to input basic parameters, the smoothness stability phenomenon can be subjected to simulated analysis, the method is simple, and operation is easy.

Description

technical field

[0001] The invention belongs to the technical field of automobile engineering, and in particular relates to a simulation analysis method for the ride comfort stability of a truck. Background technique

[0002] Ride comfort refers to the influence of the vibration and shock environment caused by the unevenness of the road surface and the rotating parts such as the engine, transmission system and wheels on the comfort of the occupants during driving; within certain limits, for trucks, it also includes Maintain the integrity of the cargo carried. The vibration during the driving process of the car will not only reduce the service life of the vehicle and increase maintenance costs; it will also affect the health of the occupants and the integrity of the transported goods; it will also affect the power and fuel economy of the vehicle. Therefore, the ride comfort of vehicles has become an important evaluation index of modern delivery vehicles. In recent years, it...
