Abstract: A direct-drive system, including: a base; a mover assembly arranged on the slide; a stator assembly arranged on the base; and at least one mover protective assembly fixed to the slide and in contact with the stator assembly. An electromagnetic force is formed between the mover assembly and the stator assembly to drive the slide to slide relative to the base; and in a direction perpendicular to a sliding direction of the slide, the mover assembly and the stator assembly are opposite to and spaced from each other to form a gap. The at least one mover protective assembly is configured to enclose the gap. The at least one mover protective assembly can enclose the gap between the mover assembly and the stator assembly, so as to effectively prevent foreign matters from entering a mover air gap and thus improving reliability of the system.

Abstract: A direct-drive system, including a base provided with a guide rail; a slider arranged on the guide rail; a mover assembly including a mover arranged on the slider and a magnet arranged on an inner side wall of the mover; a stator assembly including a stator support arranged on the base and a stator connected to the stator support; and a blocking member. The stator is inserted into the mover and arranged opposite to and spaced from the magnet. The blocking member includes a first end connected to a side of the base away from the stator support and a second end obliquely extends towards the stator and spaced from the slider. The blocking member effectively prevents foreign matters from falling onto the guide rail, thereby preventing blockage of the slider by the foreign matters on the guide rail, and thus bringing a good protective effect and effectively improving an operation accuracy of the guide rail and prolonging a service life.

Abstract: A direct-drive system, including a base provided with a guide rail and a stator assembly; and at least one slide spaced from the base and fixed to the base by means of the guide rail. A mover assembly arranged opposite to the stator assembly is fixed to the at least one slide, and the mover assembly interacts with the stator assembly to drive the at least one slide to slide on the guide rail. An orthographic projection of the guide rail onto the base along a sliding direction of the at least one slide falls at least partially at an outer side of the base. The guide rail structure is first contacted when the modules are spliced, so as to ensure smooth sliding of the direct-drive system and reduce the difficulty of assembly and maintenance of the system.

Abstract: The present disclosure provides a method for calculating wellbore friction resistance of a foam drainage gas production well. It is based on the conversion of the parameters of the gas-liquid two-phase flow Mukherjee & Brill model, it defines the liquid film reversal point as the zero friction resistance point, ignores the influence of the negative value of friction resistance, and uses this as a starting point to predict the change of friction resistance. The influence of liquid phase parameters and foaming agent concentration is taken into account in the friction resistance coefficient. An effective calculation method is obtained by combining the experimental data fitting and optimization. The present disclosure better characterizes the wellbore flow condition of the foam drainage gas production well, and provides important theoretical support for the prediction of the wellbore pressure drop of the foam drainage gas production well.

Abstract: Introduced are a method, a software apparatus, an electronic device, and a storage medium for simulating inerter using finite element analysis. The method involves: acquiring structural parameters of an inerter; simulating the mechanical properties of racks on rigid rods and flywheels within the inerter using the structural parameters and a finite element platform; formulating constraint equations and transformation formula to simulate translational-rotational conversion and inertia amplification mechanism of the inerter; integrating the force and constraint information to achieve the finite element simulation of the inerter. The finite element simulation method for the inerter addresses the challenge of lacking “inerter units” and the inability to simulate inertia components in general finite element software platforms. It also overcomes the technical bottleneck of real-time dynamic coupling simulation between inerter and complex engineering structures.
