Abstract

The invention provides a four-freedom-degree series-parallel motion platform and a dynamic simulation device. The four-freedom-degree series-parallel motion platform comprises a base, a three-freedom-degree parallel mechanism, a low-order motion platform, a rotating series mechanism and a high-order motion platform, wherein the three-freedom-degree parallel mechanism comprises at least three first driving components; the first driving components comprise first linear driving units, rotational connecting pieces and sliding pieces; the rotating series mechanism comprises a second linear driving unit, a transmission piece and a rotating piece. A purpose of the four-freedom-degree series-parallel motion platform is for the dynamic simulation device.

Description

technical field [0001] The invention relates to the field of motion platforms with few degrees of freedom, and more specifically, to a four-degree-of-freedom mixed motion platform and a dynamic simulation device. Background technique [0002] Multi-degree-of-freedom motion platforms are widely used in industrial production, dynamic simulation and other fields. For example, the three-degree-of-freedom and four-degree-of-freedom motion platforms with few degrees of freedom have the characteristics of simple structure, low cost, and large work space compared with six-degree-of-freedom motion platforms, and have broader application prospects. [0003] Most of the existing motion platforms with few degrees of freedom use the drive unit to drive the platform in the form of oblique support. The aforementioned oblique support of the drive unit means that there is always a certain angle between the drive output direction of the drive unit and the base. The motion platform adopting ...
