There is a clear difference in design and application between cylindrical shakers and square electromagnetic shakers.
First of all, from a structural point of view, the cylindrical shaker is a rotationally symmetrical shape with a cylindrical structure. This design usually has a vertical axis of rotation on which an eccentric mass is mounted. When the axis of rotation rotates at a certain speed, a periodic centrifugal force is generated, which creates vibrations in the horizontal direction. The structural design of the cylindrical shaker is simple, and it is easy to manufacture and operate.
In contrast, the structural design of a square electromagnetic shaker is more complex. It usually consists of a square frame, an electromagnetic actuator, and some supporting structures. The electromagnetic driver consists of a fixed coil and a movable core, and when an alternating current is introduced into the coil, an alternating magnetic field is generated that drives the core back and forth. This motion is transmitted to the bottom of the square frame, causing the entire shaker to vibrate horizontally.
From the perspective of working principle, the working principle of cylindrical shaker is based on the principle of centrifugal force, which generates centrifugal force through the rotation of the rotating shaft, so as to achieve horizontal vibration. The square electromagnetic shaker uses the principle of electromagnetic induction to drive the iron core back and forth through the alternating magnetic field, so as to achieve horizontal vibration.
In addition, there are certain differences in the application of cylindrical shakers and square electromagnetic shakers. Cylindrical shakers are often used to simulate vibrations in the direction of degrees of freedom, such as those in the horizontal direction. Square electromagnetic shakers, on the other hand, are more suitable for simulating vibrations in multiple degrees of freedom, such as horizontal and vertical vibrations. In addition, the square electromagnetic shaker has a wider frequency range and can simulate vibrations at multiple frequencies.
In conclusion, there are obvious differences between cylindrical shakers and square electromagnetic shakers in terms of structure, working principle and application. The cylindrical shaker has a simple structure, is easy to manufacture and operate, and is suitable for simulating vibration in a single degree-of-freedom direction; The square electromagnetic shaker has a complex structure and uses the principle of electromagnetic induction to achieve vibration, which is suitable for simulating vibration in multiple degrees of freedom and has a wider application prospect.
