摘要： The present disclosure provides a method for constructing a three-dimensional solid model with a geometric error and a computer-readable storage medium. The method includes: S10: obtaining an ideal geometric solid model of a component; S20: constructing a geometric error model for a surface of the component by use of geometric error data of the surface of the component; and S30: replacing a corresponding surface in the ideal geometric solid model with the geometric error model to obtain a three-dimensional solid model with a geometric error. The method for constructing a three-dimensional solid model provided by examples of the present disclosure integrates a geometric error of a component with a CAD model, so as to obtain a three-dimensional solid model with a geometric error, which describes a regular appearance characteristic of a real surface of the component macroscopically, and also reflects an irregular geometric error shape characteristic of the surface of the component microscopically.

摘要： The present invention discloses a soft knee exoskeleton driven by a negative-pressure linear actuator, including: an exoskeleton controller, a left leg knee joint soft actuator, a right leg knee joint soft actuator and the like. The soft knee exoskeleton mainly uses a miniature vacuum negative pressure pump as an air pressure power source. A DSP embedded control system performs real-time processing on the data, such as a muscle force, a knee joint angle and a human-machine interaction force, detected by a sensing system, estimates a human-machine cooperation state, and performs real-time control on the switching of the negative pressure flow and an air channel of the miniature vacuum negative pressure pump.
