Abstract


Brake’s performance is directly related to the safety of driving a motorcycle, motorcycle brake products for quality testing can ensure the quality of brake products ,through quality analysis of the data obtained can improve the brakes production methods, optimize the brakes production process, thereby enhance the brakes performance. This thesis combined with the "hydraulic disc brake assembly performance test-bed" project of a motorcycle manufacturing enterprise, and in accordance with the standards of the People’s Republic of China National Standard QC-T654-2005 "the motorcycles and mopeds’ brakes performance requirements and test methods", designed out the brake assembly performance test-bed for the enterprise.Introduced the motorcycle hydraulic disc brake structure and working principle in the thesis, and in the light of the standards and test methods in QC-T654-2005 " the motorcycles and mopeds’ brakes performance requirements and test methods ", explored the working principle of the hydraulic disc brake assembly performance test-bed, designed the units of the test-bed that the mechanical implementing agencies of the test-bed on the basis. The mechanical structure design of the test-bed surrounded the testing devices of the brake handle displacement, grip force and gag force mainly, including the hand pumps fixture, the simulation device and testing device of the grip force, the screw transmission and pressed device, the brake clamp pressed device, the pneumatic pipeline design and so on. In the premise of meeting the testing requirements, considered the reliability and safety of the test-bed, as well as the installation and maintenance of the various sensors and proximity switches.In accordance with the parameters and required standards of the brake assembly performance test-bed tested , selected three sensors as the front-end of the detection system; In accordance with the working environment and control requirements of the test-bed, selected S7-300 series PLC as the control equipment, S7-300 series PLC adaptable, easy to program, easy to control; In accordance with the detection and control requirements, made some corresponding set to the hardware of PLC and programmed the procedures for the control system with STEP7; Selected PC based on LabVIEW, the host computer and the control equipment communicated through RS-232C serial, the operator can operate the test-bed to detect the brake products easily through the man-machine interface, can observe the status of the test-bed equipment and test parameters in real-time, and can print out the testing parameters and the parameters’ relationship curves if necessary.The brake assembly performance test-bed studied in this thesis combined the mechanical and electronic technology, computer aided test technology and pressure transmission control technology, improved the automation and detection accuracy of the test-bed significantly, provided a more effective quality technical support for enterprise, and provided a broader application platform for measurement and control system test equipment.
