Study Of Herringbone Frame Structural Of Automobile High-speed Tire Test Machine Based On Dynamic Characteristics

High-speed car tires dynamic characteristics test machine is in automobile tires measuring high-speed (250km/h) under various performance parameters of laboratory equipment.This paper reviews the development of domestic and foreign tire test equipment, the introduction of modern technology to design high-speed tire testing machine of herringbone frame were studied. Identified herringbone frame the basic structure of its structure of the movement simulation, the thickness and herringbone frame structure has been optimized. So herringbone frame structure of a better stress distribution and deformation conditions. After the optimization of herringbone frame structure of the dynamic characteristics analysis, have been more ideal its structure .Herringbone frame is the important component of the high-speed tire testing machine of its direct impact on the test machine performance in high-speed, high-load of security and reliability. By herringbone frame functional analysis to determine the structure of Q235 plate box from structural welding. In realization of the structure, through the finite element software ANSYS APDL language in the secondary development of a ANSYS order flow establishment, the establishment of a herringbone frame structure of the parameters of finite element model. Use of recycling and branch statements extracted herringbone frame roll movement in the process of the different stress and strain rate and an important position in the image stress curve and realized the herringbone frame structure of the movement numerical simulation; Second, consider the stress distribution and economic performance through ANSYS structural optimization module thickness of herringbone frame structure has been optimized analysis. Finally, the application of ANSYS software to optimize the herringbone frame structure of the dynamic characteristics of.To meet the strength and stiffness required conditions, make herringbone frame the quality of the smallest. After optimization analysis, determined by the herringbone frame at different points with different thickness of the structure; final adoption of the herringboneframe structure optimized for dynamic analysis shows that after optimizing the herringbone frame structure with good mechanical structural dynamic characteristics proved the herringbone frame structure optimized to meet the economic indicators and performance requirements.
