Embodiment Construction

[0034] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0035] Such as figure 1 As shown, the FSC racing car frame is welded by multiple 4130 steel pipes of different sizes, and its overall size and rigidity are much smaller than those of ordinary cars. Referring to the torsional stiffness detection device of the body-in-white of ordinary cars, and considering the special structure of the FSC racing car frame and the actual conditions of the college team, we designed a measuring device that specifically measures the torsion and bending stiffness of the FSC racing car frame and is easy to use for the college team.

[0036]Principle: The common method of measuring the torsional stiffness of the frame is: fix the rear suspension mounting rod of the frame, apply a pair of eq...

Abstract

The invention relates to a measuring device for the torsional and bending stiffness of an FSC racing car frame, comprising a base plate, a front bracket, a torsion bracket, a rear bracket and a load applying device, and the base plate is provided with the front bracket, the torsion bracket and the The first guide rail of the longitudinal sliding of the load applying device, one end on the bottom plate and corresponding to the extending direction of the first guide rail is provided with a second guide rail for the lateral sliding of the rear bracket; the front bracket, the torsion After the frame of the FSC racing car is fixed and positioned by the bracket and the rear bracket, a load is applied to the frame of the FSC racing car through the load applying device, and its torsional and bending stiffness values ​​are calculated. The beneficial effects of the invention are: the measuring device has the function of measuring the torsional stiffness and the bending stiffness of the frame of the FSC racing car, and the measurement is accurate, which provides great convenience for the research of the frame of the FSC racing car.

Description

technical field [0001] The invention relates to the field of measurement, in particular to a measuring device for torsion and bending stiffness of an FSC racing car frame. Background technique [0002] Formula Student China (FSC for short) is an automobile design and manufacturing competition organized by students majoring in automobile engineering or automobile related majors in colleges and universities. FSC racing car frame torsional and bending stiffness measurement device is a measurement device specially used to detect the torsional stiffness and bending stiffness of the car frame used in the race. It mainly includes: a base, a fixing device, a twisting and bending device, a load applying device and a detection device. [0003] Since the FSC competition was introduced into China in 2010, it has received support from a large number of colleges and universities, and the number of participating teams has increased year by year. As of 2015, nearly 70 colleges and univers...
