Problems solved by technology

The chaotic vibration exciter will change the vibration frequency from a single frequency to a broadband frequency. On the basis of retaining the main frequency of the traditional exciter, a frequency multiplier component with greater energy is added; at the same time, the total excitation energy is increased. Effectively solve the problem of single excitation frequency, high energy consumption and low efficiency of the existing vibration hydraulic cylinder exciter

Abstract

The invention discloses a chaotic vibrating hydraulic cylinder. The chaotic vibrating hydraulic cylinder comprises a piston I, a piston rod, a mass cover sealing element, a mass cover, additional mass, a spring, a hydraulic control valve, a piston sealing element, a first end cover, an end cover sealing element, a second end cover, a third end cover, a hydraulic cylinder body and a bolt. The piston and the piston rod are of an integrated structure and forms mass m1. The piston rod is sleeved with an inner circle of the additional mass m2, and an outer circle of the additional mass m2 is assembled in an inner hole of the mass cover. The additional mass is in the sliding friction relation with any one of the piston rod and the mass cover or with both the piston rod and the mass cover and isconnected with the piston rod in the axial direction through the spring. The piston rod, the mass cover and the hydraulic cylinder body can each generate chaotic vibration to the outside. According tothe chaotic vibrating hydraulic cylinder, a single vibration frequency is converted into a broad vibration frequency, large-energy frequency multiplication elements are added on the basis that the dominant frequency of a traditional vibration exciter is reserved, and the total excitation energy is improved, so that the problems that an existing hydraulic vibration exciter has a single excitationfrequency and is high in power consumption and low in efficiency are effectively solved, and the application range is wide.

Description

technical field [0001] The invention relates to a chaotic vibration hydraulic cylinder, in particular to a high-efficiency vibrating hydraulic cylinder exciter, which belongs to the field of vibration engineering equipment and hydraulic technology. Background technique [0002] In the field of vibration engineering technology, the vibrator is one of the very important core vibration equipment. At present, ordinary vibrating hydraulic cylinders are single-mass or single-degree-of-freedom vibration systems, which generate a single excitation frequency. With the development of modern vibration engineering technology, higher requirements are put forward for the excitation effect, efficiency and energy consumption of vibration exciters. The existing single-frequency vibrating hydraulic cylinder exciter cannot achieve a better excitation effect in vibration engineering, and even cannot work effectively in some special occasions with low excitation efficiency and high energy consu...
