Braking Force Distribution Optimization Of Js6608 Bus

The braking system is the most important constituent of the bus, it is directly affecting the bus entire performance. In the new vehicle type development design process ,judges the vehicles braking system the rationality, by and it's the performance fit and unfit quality, and to the braking system design parameter, the performance parameter carries on the optimization, is an assorted minute important work. But, the bus braking system is one kind complex, involves the many kinds of physical parameter the distributed parameter system, this gave the research work to bring the quite great difficulty. Carries on the computation, the solution, the analysis with the manual method to it, the work load very in a big way, also is very difficult to obtain precisely superiorly melts, in the passenger train domain introduction computer hardware and software, may very convenient carry on the parameter in the braking system design to optimize and the braking quality computer simulation research.The type of JS6608 bus is the company for responds the government to summon, and according to market demand development development adaption countryside passenger transportation condition country bus. The economic security is basic. Because of the economy, many advanced control systems like ABS and so on, all cannot obtain the utilization; But, safely lets us be able not but under the existing condition, through the optimized design method, conducts the research through the computer simulation technology to the braking quality, makes some reasonable adjustments to its design parameter and the control portion, causes between the bus axle braking force to assign in the applicable scope achieves the optimization, causes the braking quality to conform to the national laws and regulations requirement.This article main content: Take the JS6608 vehicle type as the foundation, has carried on the system theoretical analysis to the bus braking system, has related in detail the main braking force adjusting device structure, the principle of work, and has established the corresponding characteristic function; And has established between the axis in this foundation braking force the assignment optimization design mathematical model and the braking quality simulation mathematical model; Through carries on the fixed ratio braking quality computation to the JS6608 original vehicle type parameter; The fixed ratio braking force assignment optimizes, after uses optimized the parameter to calculate it braking quality; Installs sets at the braking quality computation after braking force the adjustment, as well as optimizes the entire vehicle braking quality after braking force the adjusting device parameter to carry on the computation, and carries on the corresponding experimental confirmation, caused the present paper the correlation research to study and improves the design to provide the higher theory instruction function to the passenger train braking system development.As a result of work for enterprise, test condition limited, also end of mission time urgent, is very easy to let the person form one kind of contrast design the custom. The JS6608 bus as soon as starts to meet braking force does not reach the sign, the main reason lies in the design initial period the position estimate not to permit to its barycenter, the entire vehicle weight surpassed to the initial period predetermined value have been very many. Originalcomplete vehicle kerb mass: 3000kg, maximum design total mass: 4490kg.After the actual paper vehicle gets down, the complete vehicle kerb mass is: 3650kg, the maximum design total mass reaches: 5130kg. In order to consider on farmer brothers any sign, on finally announced when demarcates the parameter no matter what is: Complete vehicle kerb mass: 3000kg, biggest lumpy mass: 4490kg. Six meters about passenger trains markets, the hydraulic brake system has gradually is taken by the air braking system for the result.Investigates its reason, mainly is the design does not arrive , certainly does not remove the overload over strength , as well as necessary reason.This article took to the passenger train braking system design one kind of shallow attempt, through carries on the comprehensive theoretical analysis and the experimental study to the passenger train braking system, establishes the reasonable braking force assignment optimization design mathematical model and the braking quality computational mathematics model, and expected can develop corresponding computer software, will build the foundation for the later better development safe practical braking system.
