The inner frame is rotatably connected with the outer frame through a pin shaft. A bottom surface of the conical workpiece can be fixedly connected with an inner bottom surface of the inner frame. The base plate is removably arranged on the inner frame, and abuts against a top of the conical workpiece. The base plate is perpendicular to an axis of the conical workpiece. The laser displacement sensors are fixedly arranged at a position of the inner frame below the top of the conical workpiece. The weighing mechanisms are provided at a bottom of the outer frame, and can bear the inner frame, the outer frame and the conical workpiece.

Abstract: A conical workpiece length measurement method is provided. Two laser displacement sensors are symmetrically arranged at opposite sides of a to-be-measured conical workpiece or a tooling loaded with the to-be-measured conical workpiece. Distance X0 from each displacement sensor to a bottom plane of the to-be-measured conical workpiece is calibrated. An elongated base plate is arranged at a tip of the to-be-measured conical workpiece, and the two displacement sensors measure their respective distances to the base plate. The total length of the to-be-measured conical workpiece is calculated as follows: X=X0+(X1+X2)/2, where X1 represents distance from one of the two displacement sensors to the base plate, and X2 represents distance from the other of the two displacement sensors to the base plate. Factors influencing the length measurement include calibration of the fixed length, measurement accuracy of the displacement sensor and a tilt error of the base plate.

Abstract: A method for making a spatio-temporal combined optimal scheduling strategy of a mobile energy storage (MES) system includes: inputting data of a power system, a traffic system, and an MES system; setting a time interval, and initializing a time interval counter; inputting real-time fault, traffic, and MES data; and performing rolling optimization and solving, and delivering regulation decision instructions of the MES system, till a fault is removed. The core of the present disclosure is to propose a spatio-temporal combined optimal model of the MES system to describe spatio-temporal coupling statuses of an energy storage vehicle, a traffic network, and a power distribution network. The present disclosure provides guidance for an optimal scheduling decision of the MES system by properly regulating a traveling path and charging and discharging power of the MES system, thereby supporting high-reliability operation of the power distribution network.
