Arrangement method and arrangement system of vehicle door hinge axis

Abstract

The invention discloses an arrangement method and an arrangement system of a vehicle door hinge axis. The arrangement method of the vehicle door hinge axis comprises the following steps: inputting anouter CAS surface; setting a hinge axis and setting a vehicle door section perpendicular to the hinge axis; obtaining an auxiliary straight line according to the vehicle door section; obtaining a first auxiliary plane according to the auxiliary straight line and the hinge axis, and obtaining a parting line rear boundary according to the first auxiliary plane and the outer CAS surface; and obtaining a second auxiliary plane according to the hinge mounting bolt of the vehicle door section, and obtaining the front boundary of the parting line according to the second auxiliary plane and the outerCAS surface. According to the arrangement method of the vehicle door hinge axis, in the subsequent vehicle door hinge axis arrangement process of different vehicle types, the arrangement position of the new vehicle door hinge axis can be determined only by replacing the outer CAS surface and adjusting the related parameters of the vehicle door hinge axis, so that the arrangement work of the vehicle door hinge axis is simplified, and the design efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of vehicle manufacturing, in particular to a method for arranging a hinge axis of a vehicle door and an arrangement system suitable for the method for arranging the axis of a hinge of a vehicle door. Background technique [0002] The door hinge axis layout is an extremely important part in the development of new models, and it has a wide range of influence. Once determined, it is difficult to change later. In the prior art, the hinge axis layout method is mainly to determine the inclination angle and position of the hinge axis through the experience of engineers, and then continuously correct the inclination angle and position of the hinge axis through the DMU motion analysis results to obtain the hinge axis that meets the requirements of the door movement clearance. The hinge axis layout Because there are many parameters and are greatly affected by the external shape, once the shape is changed, the hinge ax...

[0002] The axis layout of the door hinge is an extremely important part in the development of new models, and has a wide range of influence. Once determined, it is difficult to change later

In the prior art, the hinge axis layout method is mainly to determine the inclination angle and position of the hinge axis through the experience of engineers, and then continuously correct the inclination angle and position of the hinge axis through the DMU motion analysis results to obtain the hinge axis that meets the requirements of the door movement clearance. The hinge axis layout Due to the large number of parameters and the great influence of the external shape, once the shape is changed, the hinge axis needs to be readjusted, which takes a long time and affects the progress of the feasible analysis of the project shape, and there is room for improvement
