Embodiment Construction

[0043] Combined with the accompanying drawings, taking the frame structure of an intercity bus with a length of 12.5 meters, a maximum width of 2.5 meters, and a maximum frame height of 3.2 m as an example, a low wind resistance bus body structure and its design method of bionic seals are further explained .

[0044] The body structure is as Figure 1-4 As shown, it is mainly composed of three parts: cockpit, passenger compartment and cargo compartment.

[0045] Among them, the head of the bionic seal in the cockpit is established, the upper beam of the windshield is formed by a round tube through pre-bending process, the lower beam is composed of two round tubes, and the right end of the lower beam is connected with the door arranged on the right side of the cockpit. Column beam welding. The door steps are 2 steps. There are three protruding circular bends in the front of the cockpit to form a space structure similar to the front jaw of a seal to arrange the engine, and th...

Abstract

The invention relates to a low wind resistance passenger car frame structure imitating monachus tropicalis and a design method thereof. A lateral contour, a cross section contour and a cab contour of a passenger car are respectively based on a lateral contour, a cross section contour and a head profile of a seal and are determined comprehensively taking regard of driver visual field; the outer contour of the body is provided with a bionic streamlined shape of a monachus tropicalis; a carrying-type car body frame is formed by a longitudinal beam, a cross section annular beam, a floor beam and a connecting beam of a cab which are applying to the outer shape of the passenger car; an upper body structure is formed by the floor and an upper frame; comfortable and safe riding environment is provided and standing and walking of passengers are secured; a lower body is formed by the floor and a lower frame to provide mounting space for engines and suspensions and space for luggage cases. By means of the finite element structural optimization and on the basis of bending, torsion and braking load of passenger cars, the overall car frame is optimized; rod members of passenger cars are properly adjusted or added to form a space frame of a bionic passenger car with uniform overall loading and reasonable rigidity distribution.

Description

technical field [0001] The invention relates to a bus body structure and design method, more specifically, the invention relates to a bionic Caribbean monk seal bus frame with low resistance characteristics and a design method thereof. Background technique [0002] As a main body of transportation, passenger cars have the characteristics of flexibility and large passenger capacity. With the increasing urban population, people's travel requirements and frequency have also greatly increased, and the increasingly tense traffic situation has put forward more stringent requirements for the quality of buses. [0003] Most of the current passenger cars adopt a square box structure with a large drag coefficient, which is not conducive to fuel consumption and energy saving and emission reduction. [0004] The biomimicry method develops new machinery and new technologies, or solves mechanical technical problems by understanding the structure and functional principles of organisms. A...
