Abstract

Due to a number of advantages, such as a high ratio of power transmitted to the weight of the system, the possibility of easy control and the freedom to arrange system elements on the machine, hydrostatic drive is one of the most popular methods of machine drive. The executive elements in such a system are hydraulic cylinders that convert the energy of the pressure of the liquid into the mechanical energy of the reciprocating motion. One of the disadvantages of conventional actuators is their weight, so research is being done to make them as light as possible. The directions of this research include the use of modern engineering materials such as composites and plastics. The paper presents the process of designing, FEM analysis and experimental validation of the base and gland of a composite hydraulic cylinder. The considered elements are made of PET plastic. During the analysis, material non-linearity was taken into account, and the analysis itself was carried out in two steps. The first was the preloading of the tie-rods, and the second was the loading of the cylinder with internal pressure. The numerical calculations were experimentally validated by prototype tests with the use of strain gauges.

拉杆复合液压缸塑性件设计与有限元分析
由于许多优点,如高功率传递到系统的重量比,易于控制的可能性和自由安排系统元件在机器上,静液驱动是最流行的机器驱动方法之一。这种系统中的执行元件是液压缸,它将液体的压力能量转化为往复运动的机械能。传统执行器的一个缺点是它们的重量,因此研究人员正在进行使它们尽可能轻的研究。研究方向包括复合材料和塑料等现代工程材料的应用。介绍了一种复合液压缸基座和缸盖的设计、有限元分析和试验验证过程。考虑的元素是由PET塑料制成的。在分析过程中,考虑了材料的非线性,分析本身分两步进行。第一个是拉杆的预加载,第二个是气缸的内压加载。利用应变片进行了样机试验,验证了数值计算的正确性。
