Embodiment Construction

[0023] In order to make the purpose, content and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0024] This embodiment proposes a general arrangement method for heavy trucks, such as figure 1 As shown, the method specifically includes the following steps:

[0025] S1. Use CATIA software to establish a CATPart model including vehicle parameters, large component positioning parameters, and suspension hard point coordinates and steering hard point coordinates; which not only includes vehicle parameters such as wheelbase and wheelbase, but also includes parameters such as Positioning parameters of large parts of powertrain and steering axle, design hard point coordinates of suspension system and steering system. In order to ensure the rationality of the design, these parameters and coordinates need multiple rounds of...

Abstract

The invention belongs to the technical field of vehicle total arrangement, and particularly relates to a top-down heavy truck total arrangement method based on a parameterized skeleton model. According to the method, complete forward design from top to bottom is adopted, and top layer planning is established and serves as a design criterion to be transmitted downwards step by step; The modification is very convenient, only corresponding parameters or hard point coordinates need to be modified, the point-line skeleton model, the part model and the large part are positioned, the point-line DMU model can be automatically modified, and the part motion envelope can be automatically generated; The method is suitable for a series of vehicle types of the same platform, and the requirements can bemet only by establishing one-time vehicle parameters and hard point coordinates, a one-time point line skeleton model and a one-time point line DMU model and simply modifying other vehicle types. Theworkload is greatly reduced, the sample production quantity is reduced, the product development cost is reduced, and the product development period is shortened.

Description

technical field [0001] The invention belongs to the technical field of vehicle general layout, in particular to a top-down heavy truck general layout method based on a parametric skeleton model. Background technique [0002] The general layout of heavy trucks is to arrange various systems and components such as powertrain, suspension system and steering system on the car, so that the car forms an organic whole, and then can complete various functions. High-quality general layout can ensure the avoidance of static and dynamic interference between systems during the design and development stage of the car, and finally achieve one-time verification of physical prototype loading, reduce the number of prototypes produced, shorten the product development cycle, and reduce the cost of prototype development . [0003] At present, the most widely used general layout methods mainly include two-dimensional general layout method and three-dimensional digital-analog general layout metho...
