The invention relates to a matching design method for pre-clamping stress of equal-thickness main springs of first-stage gradually changed rigidity plate springs and belongs to the technical field ofgradually changed rigidity plate springs of a suspension frame. According to the method, according to the piece number of the main springs and auxiliary springs, structural parameters of the plate springs, the starting contact load, the rated load and the allowed stress of the first piece of main spring under the rated load, matching design is performed on the pre-clamping stress of the equal-thickness main springs of the first-stage gradually changed rigidity plate springs. It can be known from a prototype test that the matching design method for the pre-clamping stress of the equal-thicknessmain springs of the first-stage gradually changed rigidity plate springs is correct, a matching design value of the accurate and reliable pre-clamping stress can be obtained, and a reliable technicalbasis is laid for design of the arc height of free tangents of the equal-thickness main springs. By means of the method, it can be guaranteed that the pre-clamping stress of the equal-thickness mainsprings meets the design requirement, the design level and the reliability of products are improved, the service life of the products is prolonged, and the running safety of vehicles is improved; andmeanwhile, the design and experiment cost of the products is reduced, and the product development speed is increased.

The invention relates to a method for fast extracting loads in a movement mechanism and an optimizing design scheme. The method includes the following steps that firstly, a movement mechanism principle diagram is built up, load conditions of the movement mechanism are determined, and a movement tract diagram is generated; secondly, load information of the movement mechanism is extracted, a movement mechanism driving load curve is automatically drawn, multiple load conditions of the movement mechanism are overlapped, and the maximum load which the movement mechanism can bear is extracted; thirdly, an initial scheme of the movement mechanism is optimally designed, and the design of the movement mechanism can be optimal finally. By means of the scheme, in the initial design period, the inner loads of parts in different conditions and moments can be fast extracted according to coordinate positions of a mechanism part so that strength persons can conduct primary strength check and optimal design on a mechanism system before obtaining a specific Catia entity model of the mechanism part, it is ensured that the design of the mechanism system is the optimal scheme from the beginning, and therefore a design period can be fully shortened and development cost is saved.

The invention provides a memory positioning device. The memory positioning device comprises a positioning mechanism, the positioning mechanism is configured to position the memory, and the positioningmechanism comprises a substrate and at least one group of positioning assemblies. The substrate is provided with at least one positioning groove penetrating through the substrate, the positioning grooves are configured to contain the memories, and the shapes of the positioning grooves are matched with the shapes of the memories. The at least one set of positioning assemblies are arranged corresponding to the at least one positioning groove, and each set of positioning assemblies comprises a plurality of positioners arranged on the substrate. The plurality of positioners are distributed aroundthe positioning groove at intervals, and the positioners are configured to adjustably position the memories. The memory positioning device can meet the positioning requirements of memories of different sizes, does not need to measure the to-be-debugged memory in advance, greatly reduces the design cost, and is better in universality.
