Problems solved by technology

However, the traditional rigid mechanical arm is designed from heavy materials. This cumbersome design inevitably leads to many problems such as low load-to-weight ratio, high energy consumption, and slow response speed during the operation of the rigid mechanical arm.
Nowadays, with the rapid development of production, the traditional rigid mechanical arm can no longer meet the development of high-speed productivity.

Embodiment

[0053] Such as figure 1 As shown, the operating relationship between modules of a two-dimensional vibration control simulation method for a flexible arm system includes the following steps:

[0054] S1. Establish a flexible mechanical arm vibration simulation visual operation interface through Matlab GUI programming;

[0055] S1.1, PDEs equation analysis, using the difference discretization method to discretize the partial differential equation, using the backward difference method to obtain w′(x,t) and Then use Matlab for numerical calculation;

[0056] S1.2. In order to achieve the real-time display effect of the vibration of the flexible manipulator and the iterative characteristics of the fourth-order operation of the flexible manipulator equation, the data is discretely processed, and only 7 time discrete points are calculated at a time to ensure the matching of the calculation speed and the drawing speed. At the same time, it also takes into account the time causal da...

Description

technical field [0001] The invention belongs to the fields of vibration control of robots, mechanical engineering and aerospace technology, and relates to a simulation system capable of simulating the motion and vibration control of a flexible mechanical arm, and in particular to a two-dimensional vibration control method for a flexible arm system. Background technique [0002] Robotic arms are widely used to assist people in dangerous, monotonous and tedious tasks. However, the traditional rigid manipulator is designed from heavy materials. This bulky design inevitably leads to many problems such as low load-to-weight ratio, high energy consumption, and slow response speed during the operation of the rigid manipulator. Nowadays, with the rapid development of production, the traditional rigid mechanical arm can no longer meet the development of high-speed productivity. The development and progress of productivity always give birth to new technologies and changes, and flexib...
