Abstract

The invention provides an automobile suspension parameterization design method. A hard point meter is used for driving point and line models of all components of a suspension, the point and line models of the components are used for building a point and line DMU (diesel multiple unit) model of the suspension, the point and line DMU module drives the suspension components to move, the DMU model of a suspension system is formed, and then, the DMU model of the suspension system is subjected to movement checking. When the method is implemented, the components, the MDU model, detail digital analog data of each component and the like are automatically changed during the suspension hard point change. The remodeling is not needed, the development period of a suspension product is greatly shortened, different automobile types can share the DMU model, the work efficiency can be greatly improved, and the development time can be shortened.

Description

technical field [0001] The invention relates to the field of digital design of automobiles, in particular to a parametric design method of automobile suspension. Background technique [0002] Suspension is an important assembly of modern automobiles. It elastically connects the body and the wheels. Its main function is to transmit all the forces and moments between the body and the wheels, and to ease the impact load transmitted to the body from uneven road surfaces, thereby attenuating The vibration caused by the bearing system controls the movement of the wheels to ensure that the car has the required ride comfort and handling stability. [0003] At present, when developing a suspension, automotive engineers first select the suspension structure according to the requirements of the vehicle, and determine the performance parameters of ride comfort and stability. Then use software such as ADAMS (Automatic Analysis of Mechanical System Mechanics) to establish a suspension dy...
