Car Instrument Panel And Skeleton Of The Optimization Design And Experimental Verification

Dashboard is one of the most main parts of the car, the function layout, on thecollision process is important for the protection of the drivers and passengers. Cardashboard system design and development process were introduced in this paper,according to brilliance auto group development of the related models, for example,describes in detail the dashboard system at the different stages of the design anddevelopment, the input, output, involved content; Dashboard system are analyzed in detailin the various regulations and under the premise of the man-machine engineering, howcarries on the feasibility analysis and optimization of the design and engineering;Describes the dashboard system to meet the various performance test and road testrequirements, etc, thus can design a collection of beauty, comfort and safety for theintegration of the dashboard system parts.In this paper in brilliance auto the project development experience, elaborated thedashboard product development process: first, clear related department to input technologyof competing goods and prices of competing goods, given the typical sections and mainsections to molding department; For modelling CAS feedback to the man-machine analysis,code analysis, feasibility analysis, technology analysis; Through multiple rounds ofanalysis, provide the final version of A surface modelling. Product design engineer with Asurface structure, process performance, swap performance is taken into account in design,mould characteristics, the complete3d data work; Optimize the3d data design, doingquick validation. Last thing to do the rounds of mould products problem rectification, thevehicle assembly matching rectification. Dashboard tooling products after coming out, onroad test road test of reinforcement design, high and low temperature test; Test structuremeet the design requirements. In dashboard development process, using computer aideddesign software, harshness (NVH) interior SR enhancement test, reverberation laboratorytest the reliability of the actual verification, test results meet the design requirements. In this paper, we mainly do the dashboard beam optimization design, aiming at theexisting problem of instrument panel beam first, CAE analysis, elaborated how to carry outthe dashboard beams in the dashboard beam design need to be aware of key points.Through multiple rounds of optimization and experimental verification, and ultimatelyreach the qualified status; Computer simulation is carried out in view of the dashboardmolds, introduce the fluid analysis software, analyzes the dashboard injection moldingprocess of changes in temperature and pressure experiment, the influence of the gatedesign for product, shorten the design cycle. Reduce development costs. Mold productionhas a guiding role for manufacturers; In products, in order to ensure to provide qualifiedproducts, combined with the problem in the road test and customer focus, experimentedwith a complete outline of writing. Each test item through the tracking and verification, toensure that the product qualified. To product design experiment and experiment gives aclear definition, is advantageous for the manufacturers and makers of products such asquality control and batch tracing test, the product status query and controllable.Practical research subject offers a reference for future design personnel, has the verygood use value. Feasibility: including the direction of the mold, material selection, processselection, each product in the dashboard installation, environmental testing, etc.The dashboard design key points are as follows:1, mode to meet the design requirements, and do not produce sound, friction,vibration, etc.;2, reliability, meet the requirements, can through the vehicle’s fatigue test;3, process feasibility: disassembly, convenient installation, maintenance, meet therequirement of process;4,and regulations meet the requirements for drivers of application security andmaneuverability.
