Abstract
The invention discloses a manufacturing method of lightweight automobile chassis parts based on rigidity and deformation analysis. The manufacturing method comprises the steps of 1) carrying out CAD molding; 2) carrying out topological optimization, shape optimization, parameter optimization, material optimization or multi-objective optimization of a whole vehicle system through utilizing a CAE, CATIA, Unigraphics, Pro/E, IDEAS or C3P method; 3) selecting lightweight materials; 4) carrying out emulation during the casting process; 5) carrying out casting result analysis and optimization; 6) casting and producing the chassis parts; 7) carrying out isothermal quenching heat treatment; and 8) carrying out machining. According to the manufacturing method of lightweight automobile chassis parts based on rigidity and deformation analysis, the weight of the chassis parts is greatly reduced and a lightweight chassis is achieved on the precondition that the performance is guaranteed.
Description
Technical field
The manufacture method relating to a kind of automotive light weight technology vehicle chassis component based on Rigidity and deformation analysis of the present invention, belongs to Trend of Auto Manufacturing Technologies field.
Background technology
China's automobile volume of production and marketing occupies the whole world the first at present, recoverable amount the second in the world.Meanwhile, energy shortage and problem of environmental pollution have become the outstanding problem of restriction China automobile industry sustainable development.No matter be consider from social benefit or economic benefit, the needs of the automobile Dou Shi conservation-minded society development of low oil consumption, low emission.Automotive light weight technology technology is the important means of automobile fuel saving, and test shows: car mass 10%. oil consumption that often decline about decline 3% ~ 5%.
This concept of lightweight originates from motor sport at first, and its advantage is understood that in fact, lightweight, can bring better handling, and the power that engine exports can produce higher acceleration.Because vehicle is light, during starting, acceleration is better, and braking distance during brake is shorter.Along with " energy-conserving and environment-protective " more and more become the topic of extensive concern, lightweight is also widely applied to general-utility car field, can also have outstanding fuel-economizing performance while raising is handling.The oil consumption of automobile depends primarily on the discharge capacity of engine and the gross mass of automobile, under maintenance Integral automobile quality, performance and the constant prerequisite even optimized of cost, reduce automobile own wt can improve power output, reduce noise, promote handling, reliability, improve the speed of a motor vehicle, reduce oil consumption, reduce discharge amount of exhaust gas, promote security.Have research numerical monitor, if vehicle complete vehicle weight reduces by 10%, fuel efficiency can improve 6%-8%; If resistance to rolling reduces 10%, fuel efficiency can improve 3%; If the transmission efficiency of the device such as vehicle bridge, speed changer improves 10%, fuel efficiency can improve 7%.Lightweight research both at home and abroad for vehicle body is many, and fewer for chassis lightweight research.Along with various countries are increasingly strict to vehicle fuel consume limit value, should strengthen the light-weighted research in chassis to reach the maximum lightweight of car load.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, a kind of manufacture method of the automotive light weight technology vehicle chassis component based on Rigidity and deformation analysis is provided.
The manufacture method of the automotive light weight technology vehicle chassis component based on Rigidity and deformation analysis of the present invention, comprises the steps:
1) CAD modeling;
2) utilize CAE, CATIA, Unigraphics, Pro/E, IDEAS or C3P method to carry out the multiple-objection optimization of topological optimization, shape optimum, parameter optimization, optimization of material or Full Vehicle System, make product quality reach minimum while have best dynamic/static rigidity and best-of-breed functionality combination;
3) select lightweighting materials, described lightweighting materials is selected from ADI material, high strength steel, aluminium alloy or polymer-based fibers reinforced composite;
4) casting process emulation;
5) interpretation of result and optimization is cast;
6) Foundry Production vehicle chassis component;
7) same temperature hardening heat treatment;
8) machining.
The manufacture method of the automotive light weight technology vehicle chassis component based on Rigidity and deformation analysis of the present invention, under the prerequisite of guaranteed performance, significantly can reduce vehicle chassis component weight, realizes chassis lightweight.
