Car frame twisting rigidity test bed of formula car and test method thereof

Abstract

The invention discloses a car frame twisting rigidity test bed of a formula car. The car frame twisting rigidity test bed of the formula car comprises a base, a front fixing beam, a back fixing beam, a rotating support seat, a rotating beam, two first fixing support seats and two second fixing support seats, wherein the front fixing beam and the back fixing beam are mutually parallel and are respectively and movably arranged on the base; the height of the front fixing beam is lower than that of the back fixing beam; the rotating support seat is fixed in the center position of the front fixing beam; the rotating beam is supported on the rotating support seat in a center-rotatable way, and can relatively rotate around the rotating support seat; when the rotating beam is parallel to the back fixing beam, the rotating beam and the back fixing beam have the basically identical height; the two first fixing support seats are movably arranged on the rotating beam and are used for connecting and fixing the front part of the vehicle frame to be tested; the two second fixing support seats are movably arranged at the back fixing beam and are used for connecting the back part of the car frame to be tested. The car frame twisting rigidity test bed of the formula car has the advantages that the structure is simple; the operation is convenient; the universality is realized.

Description

technical field [0001] The invention relates to the field of vehicle frame torsional rigidity test, more specifically, the present invention relates to a formula car frame torsional rigidity test bench and a test method thereof. Background technique [0002] The torsional stiffness of the frame determines the location accuracy of the hard point of the suspension when the vehicle is running on a twisted road. At present, the analysis of the torsional stiffness of the Formula Student racing car mainly relies on the analysis of the corresponding three-dimensional model of the frame by finite element software, and there is no test bench that can impose constraints and loads on the car frame, let alone actually test the car. The torsional stiffness of the frame. Contents of the invention [0003] The invention designs and develops a torsional stiffness test bench for a formula racing car frame. The bench structure of the invention is simple and easy to operate. [0004] Still...
