Embodiment 1

[0042] This embodiment relates to a method for determining the connection point of an X-shaped frame of a non-load-bearing vehicle, which is used to determine the position of the connection point on the frame of the non-load-bearing vehicle for connecting the frame and the body. Among them, the frame is an X-shaped structure, and the positions of the connection points on the frame for connecting the frame and the vehicle body are also scattered in different areas of the frame, so that the vehicle can be realized by connecting at multiple different positions. The stable and reliable connection between the frame and the body forms a complete body structure.

[0043] And the structure of above-mentioned X shape vehicle frame then can be as follows figure 1 As shown in , it includes a central beam body 1 in the middle, and front longitudinal beams 2 and rear longitudinal beams 3 fixedly connected to two opposite sides of the middle beam body 1, and the front and rear longitudinal ...

Embodiment 2

[0071] This embodiment relates to a non-load-bearing automobile frame. The frame is X-shaped, and its structure can be referred to the description in Embodiment 1. Several connecting pieces for connecting with the vehicle body are installed on the frame. And each connector is located on the vehicle frame at the position of the connection point between the vehicle frame and the vehicle body determined by the determination method of Embodiment 1. At the same time, the above-mentioned connectors are elastic connectors or rigid connectors, and when selected as elastic connectors When, the elastic connecting member is preferably suspended.

[0072] This embodiment also relates to a non-load-bearing vehicle, on which the above-mentioned non-load-bearing vehicle frame is arranged.

[0073] The non-load-bearing automobile frame of this embodiment and the automobile can realize the large rigidity connection between the vehicle frame and the vehicle body by arranging the connecting part...

Abstract

The invention provides a non-bearing type automobile X-shaped frame connecting point determining method which is used for determining the position of a frame body connecting point on a frame and comprises the steps of creating a frame structure three-dimensional model; importing the established three-dimensional model into finite element processing software to carry out finite element gridding processing and outputting a grid file; importing the grid file into simulation software, defining a simulation frequency interval, and simulating a frame modal diagram under each order of frequency; andcounting the frame modal value in each order of frame modal diagram, and taking the position with the maximum low modal coincidence degree in each region in different orders of modal diagrams as the position of the connection point. The invention further provides the non-bearing type automobile frame and the automobile with the connecting points determined through the method. The connecting pointposition determined by the method can achieve large-rigidity connection between the frame and the automobile body, strength complementation of the frame and the automobile body is achieved, the frameand the automobile body can serve as a whole to bear force, and the weight reduction design of the whole automobile is achieved.

Description

technical field [0001] The invention relates to the technical field of vehicle design and development, in particular to a method for determining a connection point of an X-shaped frame of a non-load-bearing vehicle. The present invention also relates to a non-load-bearing vehicle frame with the position of the connection point determined by the determination method, and a non-load-bearing vehicle with the frame. Background technique [0002] In the prior art, automobile body structures are mainly divided into load-bearing body and non-load-bearing body. The load-bearing body does not have a chassis structure that independently bears external forces, but only uses the body to support various components, that is to say, the entire body is integrated, there is no independent girder design, the suspension is installed on the body through the sub-frame, and the load of the body is transmitted through the suspension device. Give the wheels. The load-bearing body structure is lig...
