The invention discloses a quasi-zero stiffness vibration isolator installation method, a propulsion system and an underwater vehicle, and relates to the technical field of vibration suppression, and the method comprises the following steps: analyzing a vibration transmission path of a propulsion shafting in the propulsion system, and determining a main vibration transmission path and a secondary vibration transmission path; the quasi-zero stiffness vibration isolator is installed on a secondary vibration transmission path. By analyzing the vibration transmission path of the propulsion shafting, the quasi-zero-stiffness vibration isolator is installed on the secondary vibration transmission path, vibration transmission is effectively isolated, and the stiffness of the propulsion shafting cannot be obviously reduced.
本申请公开了一种准零刚度隔振器安装方法、推进系统及水下航行器,涉及振动抑制技术领域,其中方法包括:分析推进系统中推进轴系的振动传递路径,确定主要振动传递路径和次要振动传递路径;将准零刚度隔振器安装在次要振动传递路径上。本申请通过对推进轴系的振动传递路径分析,将准零刚度隔振器安装在次要振动传递路径上,不但有效隔绝了振动传递,而且不会明显降低推进轴系的刚度。
