Auto parts placement determined secret

 Auto parts placement determined secret
Source: www.qijinggm.com
      Car design is actually try a lot of ups and downs, little information available, however, from the current variety of models can be seen, even if the heart of the car - the engine can be placed in different positions, other accessories can be placed before, during and after left, right, up, down, and a wide variety of auto parts, even of different sizes, different models, placed in the position of determining the difficulty can be imagined, cited herein Gasgoo article prompted two.
 
The general arrangement in the end is what?
 
 
Many people wonder what the total is disposed in the end, an analogy will know that you recently bought a house, but it is rough room, this time you need to do this wall design, the house back into something much furniture placed in what position. Change to the car, after the location of the various assemblies, components, relationships, space, movement is not there to interfere, and operators do not meet the design requirements and legal requirements, which are arranged and belongs tube, which is simply the general arrangement is that each tube assembly, how parts should be placed, placed in what position the design stage.
 
Clear vehicle development program
 
 
Then after the general arrangement of the work is to understand what, in the end how to carry out the general arrangement of it. Generally, the total arrangement engineers need to determine vehicle technology route, the overall design process required first step in determining the size of the main parameters of the vehicle, the main performance parameters, quality parameters and the basic status of each system assembly, generally installation point and angle, select preliminary design stage layout and powertrain and tires and other models, which is the vehicle project. These parameters were determined priority vehicle general arrangement design is generally determined based on vehicle development programs, vehicle development programs including performance requirements, market requirements, design requirements, and so on. Most of these requirements are based on extensive market research and statistical analysis, there are some consulting firms offer. On the basis of this work, according to the previous leadership given to the standard car as a basis for investigation and measurement.
 
Determine the parameters of the general arrangement
 
 
In determining the vehicle performance requirements, market requirements, the design will be carried out after taking a step forward modeling requirements. In this part of the designs, the main need to determine the size of the vehicle, standing on the platform of the angle should determine the appropriate platform. After determination of the parameters required to determine the car's length, width, height, wheelbase, tread and other control dimensions, axle load distribution range and powertrain, water tank, front and rear axles, drive shafts, and wheels the size and location of the outline , then refer to similar models as well as standard data models as a reference, after the preliminary determination before the hanging and the length of suspension, front and rear windscreen position and angle of the hood height, flat floor height, dash board position, the seat arrangement, the inner space to control the size, the position of the steering wheel angle, the mutual location of the operating mechanism.
 
Develop modeling programs
 
 
When the parameters which determine the basic car, then they would be the most important point, that is, modeling designer based on the total size and arrangement of the basic elements of the design parameters of the shape of the vehicle, of course, it requires a lot of design modeling steps were to live here on a little about some of Mr. basically modeling line design department vehicle exterior and interior renderings, of course, need a variety of programs, and then handed over the leadership after engineers determined the total vehicle general arrangement Layout design verification, performed clay modeling of the vehicle to determine the overall parameters later. By constantly modify the details, after the finalization of the detailed arrangement of the various assemblies by the general arrangement of parts. When styling renderings, CAS, clay model, stepwise refinement A plane, vehicle parameters and overall dimensions of the main body to determine the basic parameters, other parameters are the size of the premise of meeting the requirements of the main dimensions, gradually arrangement design of concrete. On the contrary, the main vehicle and body size parameters identified in the preliminary modeling analysis, layout design of the continuous deepening of the revisionist and eventually can get out is determined. In this stage, through continuous adjustment to finalize the design to meet the relatively perfect vehicle modeling programs and related design, in fact, which is why the concept cars and production vehicles have the root cause of gaps.
 
Refine design details and the overall arrangement of the local check
 
 
When modeling the vehicle already has a design to meet, the next step is to refine the other details of the arrangement of parts. For example, the location of air conditioning, both inside and outside mirrors, navigation, sunroof, seat belts, armrests, seats, etc. as well as various types of electrical components, and door guard, instrument panel, all kinds of other interior panels, body interior space , luggage and body size main technical parameters for detailed arrangement OK. When these parts have been completed, entered the stage of overall vehicle data check local car, in the professional sector finished the design of the corresponding data model based on detailed modeling and general arrangement, the total arrangement on the vehicle sector needs data simulation data verification, simply means that each system, there is no interference (stationary when the collision did not hit, can not touch it after exercise) between parts, whether the space is enough (there are some regulations which fire prevention requirements, so the gap parts is also very important, tips: Do not attempt to modify the engine compartment and take the line), there is positioned about the accuracy, whether the position should be on the assembly to prevent problems from occurring. After repeated checking and modification, confirm the vehicle detailed layout program, and ultimately get the perfect vehicle data.
 
Automotive vehicle design among the general arrangement is substantially similar to these, of course, specific to how to work each manufacturer has the characteristics of each manufacturer and processes, each engineer also has the habit of every engineer in the whole amount to the car's design production stage, along with the design, testing and constant changes, the general arrangement is to keep engineers need revision and verification, through the design phase of the entire vehicle, but also to modify the maximum number of times, the need to coordinate the most problems, the meeting most engineers . Each car design, whether forward or reverse all their efforts, heartfelt tribute to the engineers for the development of China-made cars.
