Embodiment Construction

[0049] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0050] figure 1 It is a flowchart of a suspension side-view geometric motion analysis method provided by an embodiment of the present invention.

[0051] Such as figure 1 As shown, the suspension side-view geometric motion analysis method includes the following steps:

[0052] Step 101. Read suspension hard point information, wherein the suspension hard point information includes: front axle hard point information and rear axle hard point information.

[0053] A hard point is a point whose three-dimensional coordinate position is fixed and cannot be moved during the car modeling process. The hard point information of the suspension refers to the coordinates of important parts of the suspension in the vehicle body coordinate system. In this embodiment...

Abstract

The embodiment of the invention provides a side-looking geometrical movement analyzing method and system for a suspension. According to the side-looking geometrical movement analyzing method and system for the suspension, analysis and calculation of the suspension in three-dimensional space are simplified to analysis and calculation in a two-dimensional plane, the calculation process is simplified, the calculation time is shortened, and convenience is brought to engineering practical applying. The side-looking geometrical movement analyzing method and system for the suspension meet the requirements for the calculation accuracy of general side-looking geometrical performance parameters and can be used for early-stage designing and parameter optimization of the suspension in the type.

Description

technical field [0001] The invention relates to the technical field of analysis and measurement control of automobiles, in particular to a method and system for analyzing geometric motion of a suspension side view. Background technique [0002] In the initial development process of vehicle model products, the geometric motion analysis of the suspension is an important theoretical basis for the design of the suspension system. The geometric motion analysis of the suspension can solve the kinematic model of the suspension, and at the same time determine the geometric parameters of the suspension mechanism and their changing laws. The geometric motion analysis of the suspension is the basis for the analysis of the influence of the suspension geometric layout and the suspension system parameters on the performance of the vehicle. Due to the complexity of the automobile suspension structure, mathematical methods such as multi-body dynamics are generally used to analyze it. This ...
