Embodiment Construction

[0017] Simulation calculation

[0018] The mass of the exciter mechanism is M = 20 kg, the eccentricity e = 50 mm, and the mass of the counterweight m 1 = 1 kg, the angle between the slideway and OOc is θ= π / 4, l 01 = 20 mm, l 02 = 20 mm, slideway length d = 100 mm, elastic coefficient a of nonlinear spring = 2. 0×10 5 , b = 1. 4×10 4 , the rotational speed of the eccentric wheel ω= 10π (running at a constant speed). Instructions attached figure 2 is the amplitude spectrum of the reaction force of the support of the eccentric mechanism with 1 pair of slider spring mechanism, the specification image 3 is the amplitude spectrum of the reaction force of the support of the eccentric mechanism with two pairs of slider spring mechanisms. Attached from the manual figure 2 , 3 It can be seen that the frequency components of the vibration excitation generated by the improved eccentric wheel mechanism are relatively wide and numerous. In addition to producing multip...

Abstract

Provided is a novel wideband vibration exciter. Springs, sliding blocks and sliding grooves are symmetrically arranged on an eccentric wheel at one end of an original vibration exciter to generate wideband excited vibration. The wideband eccentric vibration exciter can provide rich frequency components, on the basis that basic frequency excitation of a traditional vibration exciter is maintained, multiple frequency components are added, and therefore the vibration exciter can have good adaptability, and work efficiency is vibration exciting can be improved.

Description

technical field [0001] The invention relates to the field of vibration exciters, in particular to a novel broadband vibration exciter. Background technique [0002] For most vibration mechanisms in engineering practice, the vibration is mainly driven by the inertial exciter, so the structure and performance of the exciter directly have a great impact on the working efficiency of the vibration mechanism. Vibration compaction equipment currently used in the construction industry, such as vibrating rods, frog ramming machines and vibratory impact rammers, all have the defect of single or rare excitation frequency, and this defect has a great impact on their work efficiency. In order to overcome the above defects, many experts and scholars have done a lot of useful work here, and some exciters use multiple frequency (two frequency components) or frequency conversion technology. However, if the multiple frequency technology is used, the frequency components are fixed, which make...
