The mechanical product multi-station laser welding machine comprises a workbench, a laser, a three-axis module, an inclination mechanism, a laser head, a feeding mechanism and the like; the workbench is internally provided with the laser, the top of the workbench is provided with the three-axis module, the laser head is installed on the three-axis module through the inclination mechanism, and the laser head can adjust the pitch angle under the action of the inclination mechanism. Through the clamping piece, in the process of clamping the workpiece, when one small semicircular block contacts the workpiece, the large semicircular block and the middle semicircular block will automatically rotate until the other small semicircular block contacts the workpiece, and then the large semicircular block and the middle semicircular block stop rotating, so that each small semicircular block clamps the workpiece, so that the workpiece can be fixed more stably, and the fixation of workpieces with different shapes can be adapted.

A computer-implemented method of designing a 3D modeled object representing a mechanical product. The 3D modeled object has a feature tree and an original value of a set of semantic parameters. The method includes by a user graphically interacting with the 3D representation graphically selecting a semantic point of an outer surface of the 3D modeled object and graphically selecting one or more target 3D positions of the semantic point. The method further includes, automatically, iteratively modifying the value of the set of semantic parameters. Thereby the method obtains an updated value of the set of semantic parameters. The method further includes, automatically by the CAD system, updating the 3D representation of the 3D modeled object based on the updated value of the set of semantic parameters. This provides an improved solution for updating 3D modeled objects based on graphical interactions.

This invention relates to a method for evaluating the life distribution function of a wind turbine, comprising the following steps: collecting the time of occurrence of a wind turbine failure, the location of the failure (specifically down to the component), the failure mode, and the failure impact, and performing relevant statistical listing; cleaning the collected failure data (t1, t2, ...) to remove outlier data; estimating the parameters of the three distribution functions (exponential distribution function for conventional electronic products, Weibull distribution function for simple mechanical products, and normal distribution function for mechatronic products) using the cleaned data, and fitting the life distribution according to the following mathematical model: taking the distribution function corresponding to the minimum value after fitting the three distribution functions, which is determined as the life distribution function of the wind turbine, and using this life distribution function to evaluate the life of the wind turbine.

The invention belongs to the field of macromolecules, and relates to a fat aromatic copolyester foaming composition, fat aromatic copolyester foaming beads, a preparation method of the fat aromatic copolyester foaming beads and a foaming bead forming body. The composition comprises fat aromatic copolyester, a shrinkage inhibitor, a stiffening agent, a compatilizer and an auxiliary agent, based on 100 parts by weight of the fat aromatic copolyester, the content of the shrinkage inhibitor is 0.2-2 parts by weight, the content of the stiffening agent is 0.2-5 parts by weight, the content of the compatilizer is 0.1-2 parts by weight, and the content of the assistant is 0.01-2 parts by weight; the shrinkage inhibitor is selected from at least one of polysorbate, sucrose ester, sorbitan fatty acid ester, palmitic acid diglyceride and isosorbide dinitrate. The shrinkage inhibitor, the stiffening agent and the compatilizer are used and play a synergistic effect, so that the shrinkage rate of the fat aromatic copolyester-based foamed bead is obviously reduced, and the application fields of a molded body in electronic and electric appliance packaging, precision mechanical product packaging and the like are expanded.

The utility model discloses a kind of orthotic braces, belong to human health care mechanical product technical field, including waistband to be fixed on human body, it has the vertical cloth belt extending along human spine direction;Second elastic member is fixed on the vertical cloth belt, it has the second bending part protruding to human back side, the second bending part is supported on human body, dynamic deformation is generated with human back bending, support force on human back is adaptively adjusted. The vertical cloth belt of waistband and the synergistic effect of second elastic member, dynamic support to human spine is realized. When user bends, second elastic member will automatically adjust bending amplitude with back curve, provide progressive support force, avoid the rigid restraint feeling of traditional waist support. This intelligent adjustment mechanism is particularly suitable for people who need to maintain a sitting position or bend for a long time, which can provide sufficient waist support and ensure flexibility.
