2results about How to "Reasonable design method" patented technology

The present invention relates to the technical field of automobile structural design optimization methods, and specifically refers to a trunk lid bent tube hinge axis arrangement calculation optimization method. According to the rear modeling CAS surface, as well as known design parameters and set constraints, the trunk lid initial opening θ0 and the hinge axis initial coordinate f0 are set; a hinge optimization area is constructed, and within the hinge optimization area, the trunk lid initial opening θ0 and the hinge axis initial coordinate f0 are calculated based on the hinge span design requirements, human-machine goals, the safety gap of the hinge relative to the sealing strip movement, the safety gap requirements of the trunk lid and the rear windshield during the opening process, the assembly space distance between the hinge axis and the rear windshield, and the trunk lid closing force requirements to obtain the optimal solution for the hinge axis. The optimization method of the present invention is reasonably designed, with rich considerations, avoiding the risk of repeated modifications in the later stage, improving the efficiency of the hinge axis design and development, and has great promotion value.

The application provides a design method of a reverseable gas turbine sliding bearing tile oil supply device, which comprises the following steps: S1, giving design input; S2, determining the number n of oil supply pipes; S3, determining the diameter phi of the oil supply pipes; S4, determining the positioning size L and alpha of the nozzle; S5, determining the diameter d and the spacing L of the nozzle; S6, calculating the oil flow; and S7, processing the reverseable gas turbine sliding bearing tile oil supply device meeting the design. K The design method scheme is reasonable, the design flow is clear, the guidance is strong, and the efficiency of the reverseable gas turbine sliding bearing tile oil supply device is greatly improved. The application is used in the domestic reverseable gas turbine sliding bearing design for the first time, and has very important reference value in the future gas turbine sliding bearing design.
