Abstract: The disclosure discloses a magnesium alloy for wheels, comprising in mass percentage: Al: 2-3.0 wt. %; Zn: 0.5-1.0 wt. %; Mn: 0.3-0.5 wt. %; Ce: 0.15-0.3 wt. %; La: 0.05-0.1 wt. %, the balance is Mg. The magnesium alloy of the present invention takes Al element and Mn element as main alloying elements, supplemented by trace Ce and La elements as alloying process, and the nano-scale Mn-rich precipitated phase obtained during homogenization and the segregation of rare earth elements Ce and La at the interface and grain boundary of Mn-rich precipitated phase are used to inhibit the coarsening during extrusion and forging, so as to improve the strength and plastic deformation ability of the alloy.

Abstract: The disclosure relates to the technical field of hydraulic pneumatic systems, in particular to an electric control valve detection plug and an electric control valve signal detection method. The disclosure can accurately measure the electric control signal actually obtained by the valve, thus avoiding the risk of misjudgment. The disclosure has simple manufacture and convenient installation and disassembly.

Abstract: The present disclosure provides a visual model for image analysis of material characterization and analysis method thereof. By collecting and labeling big data of microscopic images, the present disclosure establishes an image data set of material characterization; and uses this data set for high-throughput deep learning, establishes a neural network model and dynamic statistical model based on deep learning, to identify and locate atomic or lattice defects, and automatically mark the lattice spacing, obtain the classification and statistics of the true shape of the microscopic particles of the material, quantitatively analyze the tissue dynamics of the material.

Abstract: In an electric valve provided by the present invention, a gear reduction mechanism comprises a first ring gear, a second ring gear as well as an upper planetary gear assembly and a lower planetary gear assembly arranged in the longitudinal direction of the electric valve; at least part of the first ring gear is located in an inner cavity of a rotor member; an input gear part of the rotor member meshes with planetary gears of the upper planetary gear assembly; and the lower planetary gear assembly is rotatably connected to a transmission rod. In this embodiment, at least part of the first ring gear is located in the inner cavity of the rotor member, thereby reducing the size of the electric valve.

Abstract: The present disclosure belongs to the technical field of tests of automobile wheels and automobile chassis suspension systems, and provides a simulated pavement rotary drum and automobile test equipment. A simulated cobblestone pavement, and a simulated impact pavement, so that a testing pavement at a test field is reproduced; an impact load caused by the track pavement, the cobblestone pavement, and the impact pavement can be applied to wheels and a chassis system; and a road simulation test of wheels and a suspension system of an automobile can be performed on bench test equipment. As verified, the simulated pavement rotary drum of the present disclosure can reproduce the simulated track pavement at the test field; and the consistency of radial impact loads is greater than 95% at the same speed and under the same vehicle load operating condition.

Abstract: Disclosed is a method and system for adjusting process parameters of a die-casting machine, and a storage medium. The method and the system can receive die wheel type, molten aluminum temperature, interruption time and defect information in real time, respond to the above information one by one according to a set response priority order, select die-casting process parameters, and automatically adjust different process parameters for different products and different working conditions, thereby realizing simultaneous control of multiple die-casting machines, replacing manual adjustment and improving product quality stability and production efficiency.

Abstract: The invention discloses a non-pneumatic tire, comprising a wheel hub; an annular belt located on the periphery of the wheel hub; spokes comprising a plurality of spokes circumferentially arranged between the annular belt and the wheel hub; each spoke being V-shaped, and the spoke comprising two inclined plates arranged at an angle and an arc-shaped apex corner area formed at the joint of the two inclined plates; a resistance part for limiting the deformation amount of the apex corner area to a deformation amount corresponding to the yield strength. According to the invention, plastic permanent deformation of spokes can be effectively avoided by adding resistance parts, and further the service life of non-pneumatic tires can be prolonged.

Abstract: The present disclosure belongs to the field of machining of chamfers of holes. The hole chamfering device includes blades in bilateral symmetry and a blade distance adjusting, through the blade distance adjusting, the distance between the blades on the left side and the right side can be adjusted, thus, after the blades on the left side and the right side of the hole chamfering device process chamfers on the front face of a hole, the distance between the blades is reduced to enable the blades to pass through the hole to process chamfers on the back face of the hole, after processing of the chamfers on the back face of the hole is completed, the distance between the blades is reduced, the hole chamfering device not only can chamfer the front face of the hole, but also can chamfer the back face of the hole.
