The Package Of The Vehicle Based On Ergonomics

The packaging of the vehicle always exists in the research and development process.It is a work that needs to be negotiated and coordinated continuously.Based on rational package、 convenience and operation safety,The purpose is to select parameters such as body size and package form accurately and get The optimal result of the overall package.Also,it aims to set design standards for the other design departments to ensure that the designed vehicles meet the requirements at the early stage of the design.With the continuous refinement of the design work,the packaging gradually evolves into the packaging of the lower body and the packaging of the upper body.The packaging of the ergonomics on the upper body is closely related to the utilization rate of the vehicle space and the safety of drivers,and the comfort of drivers and occupants.Therefore,in the process of research and development,the status of automobile ergonomics is very important.At the same time,it can also explain the design idea of modern car based on people.This passage takes a car as an example,using the Chinese men’s and women’s human body model provided in RAMSIS software as an analysis object,analyzing the places that the drivers and passengers can reach based on ergonomics.At the same time,the driver’s comfortable sitting position is directly arranged by RAMSIS,which can reduce the analysis progress of the comfort of drivers and occupants,thereby shortening the development cycle.After the ergonomics packaging of the drivers and passengers,the windshield datu m points,the A column obstacle angle and the inside and outside rearview mirror of t he car were checked respectively,according to the latest regulation-GB-11562-2014 and GB-15084-2013.It turns out that the design meets the national standard..Finally,the limited opening angle of the engine cover and the trunk lid are analyzed by RAMSIS software.After the completion of the design and analysis,the reachable of the drivers and A column obstacle angle were checked by SAE standard,the national standard and the RAMSIS software.Among them,after the analysis of the reachable of the drivers,the results of the RAMSIS software are more stringent than the results of SAEJ287.After analyzing and verifying the obstacle angle of A column,the results are as follows: the obstacle angle calculated by RAMSIS software is larger than that calculated by SAE J1050 and both of them are larger than that calculated by GB-11562-2014.Therefore,for the result of checking the reachable of the drivers and A column obstacle angle,the results obtained by RAMSIS software are relatively strict,and the operation is more convenient and faster,so it is recommended.
