Abstract

With the development of human society, the concept of “carbon neutrality” has gradually attracted people’s attention. However, due to the existence of throttling loss, the efficiency of the hydraulic systems widely used is usually lower than 30%. In order to improve the energy conversion rate of the inefficient hydraulic system, a new type of multi-pump and multi-motor (MPMM) driving system is proposed, which can meet the flow and pressure requirements of different working conditions by switching the operation modes. In this paper, a functional symbol representation method of MPMM is specified and a systematic method of how to determine the operation mode of MPMM driving system is presented, which lays the foundation for the design of a new MPMM driving system. The test bench is built up and the correctness of the MPMM principle is verified. In addition, the comparative study of the conventional and the novel system is conducted. The results show that the input power of the hydraulic system adopting MPMM can be significantly reduced.
