Embodiment Construction

[0066] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0067] like figure 1 As shown, the present invention proposes a kind of analysis system for opening and closing force of the trunk lid of an automobile, including framework program, VB execution code and import and export template;

[0068] The external load applied to the trunk lid in the present invention includes opening force or closing force;

[0069] The framework program is used to realize the functions of importing, setting, running, editing and exporting, and selects and runs related programs according to the received basic parameters and modes;

[0070] The VB execution code is used to extract the parameter information imported into the framework program and calculate the external load (that is, the opening force or closing force) under the opening angle of the trunk lid, and generate the calculation result into a data file for the framework program ...

Abstract

The invention provides a car trunk lid opening/closing force analysis system. The system comprises a framework program and executive codes; the framework program is used for achieving the functions ofimporting, setting, running, editing and exporting, and running related programs according to received basic parameters and mode selection; the executive codes are used for extracting parameter information imported to the framework program, calculating an outer load under an opening angle of a trunk lid, namely, an opening or closing force of the trunk lid, and generating a data file for the framework program to read by a calculation result; the frame program comprises selection of opening and closing modes, and the corresponding executive codes are called by selecting different modes; and by executing relevant functions in the codes, the parameter information is called, a parameter equivalent relation is calculated, the opening force and the closing force are calculated, and an outer load curve is correspondingly drawn. According to the system, the working efficiency is improved while a high-precision analysis result is ensured.

Description

technical field [0001] The invention relates to the technical fields of automobile product design and CAE, in particular to a calculation method for opening and closing force of a trunk lid of an automobile and a software system for automatically generating external load curves. Background technique [0002] Automotive product design refers to the development of products that meet the needs of users by drawing product program engineering drawings and calculation and analysis to meet performance design requirements. [0003] CAE (Computer Aided Engineering) refers to computer simulation based on theoretical analytical solutions. [0004] The opening and closing force of the trunk lid of a car has an important impact on the user's perception when using the trunk lid. In the process of model development, analyzing and optimizing the opening and closing force of the trunk lid of the car can effectively predict and improve the air quality of the real car. The design risk of matc...
