This application discloses a servo driver and its control method, as well as a servo system, relating to the field of servo driver control technology. The control method for the servo driver includes: acquiring the current position command of the servo driver; determining the rigid position output signal and the flexible position output signal of the servo driver based on the current position command; fusing the rigid position output signal and the flexible position output signal to obtain the target position command of the servo driver; and controlling the servo driver to operate according to the target position command. This application can ensure the position control accuracy of the servo system while ensuring the normal operation of the electronically controlled equipment in the servo system.

This utility model discloses a footwear product, including: a sole and an upper. On the side view projection surface of the footwear product: the lower surface of the sole forms a continuous, upward-curving, arc-shaped rolling profile extending to the front of the sole in the forefoot area, and a ground-contacting plane in the heel area; a sole reference plane is defined by the lowest point of the arc-shaped rolling profile and the ground-contacting plane; the lowest point of the arc-shaped rolling profile corresponds to the posterior side of the metatarsal region of the foot; the ratio of the distance from the forefoot of the arc-shaped rolling profile to the sole reference plane to the projected length of the arc-shaped rolling profile on the sole reference plane is 1:1.4 to 1:1.6; the upper surface of the upper forms a continuous, upward-curving arc-shaped profile extending to the front of the shoe in the toe area, curving upwards to its highest point and then downwards; the lowest point of the arc-shaped curved profile at the toe is parallel to the sole reference plane, defining a toe reference plane, and the lowest point of the toe corresponds to the toe-heel area of ​​the foot. This footwear product can improve the adverse effects of long-distance running on runners' toes.

The application discloses an analysis method for silicon and manganese alloy element enrichment behavior of hot-rolled plate coil oxide scale, and belongs to the technical field of hot-rolled plate coil surface oxide scale detection and evaluation, comprising: sampling, preparing a sample for a test section, identifying the hierarchical structure of the oxide scale, the oxide scale-matrix interface and the abnormal area, determining the measurement path and / or measurement area across the thickness direction of the oxide scale and the oxide scale-matrix interface; screening and positioning silicon (Si) and manganese (Mn) in the test section, quantitatively performing line scanning and / or area scanning on the test section by using EPMA to obtain concentration distribution data of target elements; establishing a coordinate system, determining the reference concentration of the target elements, and calculating the enrichment index according to the concentration distribution data; comparing the enrichment index with a pre-established pickling defect risk threshold value, and outputting the result. The application solves the problems of insufficient authenticity of the test section, non-uniform measurement path, difficult comparison of the results and insufficient stability of the determination basis in the prior art.

The invention relates to a heat dissipation plate, terminal equipment and a preparation method. The heat dissipation plate comprises a first cover plate and a second cover plate which are oppositely arranged, a sealed working medium phase change space is formed between the first cover plate and the second cover plate, and the working medium phase change space is filled with a working medium; the blocking part is located in the working medium phase change space, connected with the first cover plate and the second cover plate and used for dividing the working medium phase change space into a first phase change area and a second phase change area which are arranged in parallel; the first phase change area is used for allowing the liquid working medium to circulate; the second phase change area is used for allowing the vapor-state working medium to circulate; wherein the material of the first cover plate and / or the material of the second cover plate comprise at least two different materials. The heat dissipation plate is provided with the space for working media in different states to circulate, so that the heat dissipation plate has efficient heat dissipation performance; and the heat dissipation plate is made of at least two different materials, so that the preparation flexibility is realized.

The application discloses a segmented installation method of a tunnel pile foundation steel reinforcement cage under an ultra-low clearance condition and relates to the technical field of tunnel pile foundation construction. The segmented installation method of the tunnel pile foundation steel reinforcement cage under the ultra-low clearance condition comprises the following steps: first, a light steel reinforcement framework containing only stirrups and reinforcing hoops is prepared and is lowered to the bottom of a hole in sections; then, a plurality of longitudinal main reinforcements are sent into the hole from the hole opening and are sunk to the bottom of the hole under the dead weight, and a pile end anchoring body is formed by grouting; a corrugated pipe is sleeved on the top end of the lower main reinforcement which needs to be lengthened to form an annular cavity, the bottom end of the upper main reinforcement is processed into an expanded end head, the expanded end head is inserted into the corrugated pipe after the corrugated pipe is filled with anchoring slurry, and slurry anchoring splicing is completed, and after all the main reinforcements are lengthened in turn, the pile body concrete is poured through a guide pipe. The application changes the mechanical connection at the hole opening into the anchoring of the flow state material in the hole, and the clearance required for construction only needs to meet the passing of a single component, so that the segmented installation of the steel reinforcement cage under the ultra-low clearance condition is facilitated.
