Mixing and whipping device based on a piston crank-slider mechanism

The device for mixing and whipping based on a piston crank-slider mechanism operates in the rotational mode of the drive link. With minimal engine power, the piston with the slider rises up, the connecting rod slows down, and after bypassing the engine shaft (crank), the connecting rod and the piston with the slider moves downwards at an accelerated rate. The force of the piston's interaction with the liquid was measured by a CALL DYLY-103 force load cell, which was integrated into the slider and connected to the ZET 058 strain gauge station and then to a computer. Using the ZETLAB software, oscillograms of the forces acting on the slider were obtained for various modes of operation of the prototype mixing-whipping device. According to the obtained oscillograms of forces, the maximum forces of interaction of the piston with the liquid for various modes were estimated. The linear acceleration of the slider was measured using a ZET 7052-N digital accelerometer, which is connected to a computer via the ZET 7076 interface. Using the filtering program, the linear velocity of the slider was obtained, which was recalculated through the transfer function of the device into the angular velocity of the crank.基于活塞曲柄滑块机构（piston crank-slider mechanism）的搅拌搅打装置，以驱动连杆（drive link）的转动模式运行。在发动机输出功率极低的工况下，搭载滑块的活塞向上运动，连杆随之减速；在绕过发动机曲轴（crank）后，连杆与搭载滑块的活塞将以加速速率向下运动。活塞与液体间的相互作用力，通过集成于滑块上的DYLY-103型测力传感器（CALL DYLY-103 force load cell）进行采集，该传感器依次连接至ZET 058型应变测试站（strain gauge station），最终接入计算机。借助ZETLAB软件，研究人员获取了该原型搅拌搅打装置在不同运行模式下的滑块受力示波图（oscillograms of the forces）。基于所得的受力示波图，可估算得到不同工况下活塞与液体间的最大相互作用力。滑块的线加速度（linear acceleration）通过ZET 7052-N型数字加速度计（ZET 7052-N digital accelerometer）测量，该加速度计通过ZET 7076型接口（ZET 7076 interface）与计算机相连。通过滤波程序（filtering program）处理后，得到滑块的线速度（linear velocity），并通过装置的传递函数（transfer function）将其换算为曲轴的角速度（angular velocity of the crank）。
