Disclosed in the present invention is a floating swash plate-type axial plunger pump comprising a transmission mechanism capable of driving return discs at a constant speed by main shafts, comprising two drive mechanisms, i.e. a "three-pivot ball joint-spherical roller type" drive mechanism and a "ball cage joint-ball type" drive mechanism, achieving constant-speed synchronous rotation of four components, i.e. main shafts, ball joints, return discs and cylinder blocks within a full operation period, breaking through an insufficient periodic lateral contact force/friction force peak value of a plunger pair caused by plungers successively driving the return discs in turns to rotate in the prior art, and comprehensively and thoroughly reducing the lateral contact force/friction force of the plunger pair. A pre-pressurizing/pre-depressurizing noise reduction containing chamber is provided in a central recess part of a rear end cover, thereby reducing pump source flow pulsation of the plunger pump and pressure impacts on a plunger chamber while not affecting requirements for a mounting space. As part of oil in ports of a valve plate flows into oil storage slots via fixed-clearance damping slots, and there is a variable clearance fit effect between the cylinder blocks and the valve plate, hydrostatic bearing is formed at cylinder block-valve plate friction pairs.

The invention relates to the field of milling, specifically a point position layout optimization method and a follow-up support head in mirror milling. It features an annular and linear sliding module to design a support head with adjustable support points. A corresponding layout optimization method is developed, starting with a coupled vibration model of the machining process. A layout optimization model is then created, with the quantity of support points and the support radius as decision variables. The goal is to minimize vibration amplitude and root mean square, constrained by structural interference and boundary conditions. The solution is achieved using a particle swarm optimization algorithm, supplemented by parameter scanning and a penalty function strategy. This invention addresses the limitations of existing single support point layouts for the mirror milling of various large thin-walled workpieces.

The present invention measures the collaboration efficiency of the production processes with indices such as estimated wasted time, and calculates the estimated wasted time by the expectation of the weighted sum of wasted time. For the collaboration of the production processes with uncertain time, the propagation of uncertainty factors and occurrence of wasted time in the collaborative production process are limited in a manner of takt. In different scenarios focusing on the collaboration efficiency and completion probability of the production processes, two takt control models are established, and takt solutions for the collaboration of production processes with uncertain time are obtained by solving the models. The method proposed effectively reduces the wasted time in the production processes and improves the collaboration efficiency.
