| Abstract |
As the research object, the mobile robot chassis is designed. Firstly, the mobile robot
chassis intensity design is processed in accordance with the chassis external load. According to the
design results, the structure model is constructed in ANSYS, the strength and stiffness is checked
and its structural dynamics characteristic is computed. Then, based on the numerical value analysis,
the non-sensitive variable of the bodywork is analyzed and the optimization model of the body
structure is established. The result of the Numerical Optimization proved that, the inherent structure
frequency characteristics did not change significantly in the case of the body weight components
reduced. The mobile robot platform is set up in the laboratory, the experimental results showed that
the robot chassis design is reasonable, in line with the requirements of mobile robots. |
