Embodiment 1

[0038] A motion simulation analysis method for a falcon wing door, comprising the following steps:

[0039] (1) if figure 1 As shown, the falcon wing door dynamics model is established in Adams / car;

[0040] (2) Design the movement of the falcon wing door;

[0041] (3) Run the simulation calculation and perform post-processing of the results;

[0042] (4) Activate the strut force to restore the movement process of the falcon wing door.

[0043] Described step (1) is specifically:

[0044] (1.1) Establish a hard point; respectively establish the hard point coordinates of the installation point of the falcon-wing door top door strut and side door strut, the side door hinge center and the top door hinge center, the top door and the side door mass center;

[0045] (1.2) Establish the top door and side door part, and give quality;

[0046] (1.3) Establish a kinematic pair; respectively establish a ball pair at the connection point of the side door side and the top door side fo...

Abstract

The invention discloses an eagle wing door motion simulation analysis method. The method comprises the following steps: (1) establishing an eagle wing door dynamic model in Adams / car; (2) designing the movement of the eagle wing door; (3) running simulation calculation, and performing result post-processing; and (4) activating the supporting rod force, and restoring the eagle wing door movement process. In the multi-body simulation software Adams, the multi-body dynamic model of the eagle-wing door is established, the whole opening and closing process of the eagle-wing door is simulated, the movement speed of the eagle-wing door, the stress of the supporting rod and the like are extracted, and important support is provided for development of the eagle-wing door.

Description

technical field [0001] The invention relates to a falcon-wing door, in particular to a motion simulation analysis method for a falcon-wing door. Background technique [0002] The front and rear doors of a traditional car open in one direction. This kind of side-opening door is used in most mass-produced cars, and the design and manufacture of the door is very mature. In recent years, with the development of design and manufacturing technology of car body and opening and closing parts, many new car doors have been designed, such as side-by-side doors, scissor doors, gull-wing doors, eagle-wing doors, butterfly doors, etc., most of which are in the concept In the research stage, the falcon-wing doors have been used by Tesla on the production car Model X. Falcon wing doors are favored by users because of their convenience in getting on and off, strong practicability, and a sense of technology. However, apart from Tesla, there are no mass-produced models of falcon wing doors i...
