Problems solved by technology
[0004] Due to the limitations of shape and light weight, it is difficult to design an overly long front side beam to absorb collision energy for various small electric vehicles. Therefore, it is necessary to design a reasonable deformation guiding mechanism to enhance the crushing energy absorption effect and achieve the maximum energy. absorption rate, and improve vehicle safety

The invention discloses a determination method and a device of deformation guide mechanism of front longitudinal beam of electric automobile. The method comprises the steps of determining maximum collision acceleration based on design safety level of automobile, and determining design length of front longitudinal beam; determining maximum axial compressing force in conquassation based on maximum collision acceleration and weight of electric automobile; determining a deformation guide mechanism whose axial compressing force is the maximum value and design parameters of deformation guide mechanism, arranging deformation guide mechanism on the front longitudinal beam conforming to design length according to design parameters; or determining at least two deformation guide mechanisms whose combined axial compressing force conforms to maximum axial compressing force and design parameters of at least two deformation guide mechanisms, and arranging at least two deformation guide mechanisms on the front longitudinal beam conforming to design length according to design parameters. The invention can enhance conquassation energy absorption effect and improve automobile safety.
Description
technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a method and a device for determining a deformation guiding mechanism of a front longitudinal beam of an electric vehicle. Background technique [0002] Energy shortages, oil crises and environmental pollution are intensifying, which have a huge impact on people's lives and are directly related to the sustainable development of the country's economy and society. All countries in the world are actively developing new energy technologies. As a new energy vehicle with reduced oil consumption, low pollution, and low noise, electric vehicles are considered to be an important way to solve the energy crisis and environmental degradation. Hybrid vehicles take into account the advantages of pure electric vehicles and traditional internal combustion engine vehicles at the same time. On the premise of meeting the requirements of vehicle power and mileage, it effectively improves ...
