Abstract
The application is suitable for the technical field of window design, and particularly relates to a door and window hinge structure optimization method and a door and window hinge. The method comprises the following steps: for each fitting level, based on the gap configuration data and the torque data corresponding to the fitting level, determining the tolerance sensitivity corresponding to the fitting level; based on the tolerance sensitivity corresponding to the fitting level and the sensitivity threshold value corresponding to the fitting level, and based on the gap safety interval data and the gap fluctuation range corresponding to the fitting level, determining a dangerous fitting level; for each dangerous fitting level, trying to execute the parameter adjustment strategy in turn according to the preset strategy priority order until the tolerance sensitivity of the dangerous fitting level is reduced to below the sensitivity threshold value and the manufacturability constraint is met; and determining the adjusted structure parameter of the dangerous fitting level as the target structure parameter corresponding to the dangerous fitting level. The method provided by the application can solve the problem that the optimal gap is located at the edge of the normal zone in the traditional method, thereby causing low product quality in manufacturing.
