Embodiment Construction

[0068] The present invention will be further described in detail with reference to the accompanying drawings and demonstration configurations.

[0069] see figure 1 , Figure 1A As shown, the present invention is a reconfigurable flexible teaching aid for demonstrating the dual relationship between degrees of freedom and constraints in the teaching of mechanical principles. The teaching aid includes a dynamic platform 1, a static platform 2, a disassembly tool 3, a first rod 4. The second rod 5, the third rod 6, the fourth rod 7, the fifth rod 8 and the sixth rod 9 are assembled between the moving platform 1 and the static platform 2 by combining different configuration rods Flexible teaching aids with different degrees of freedom can be formed between them.

[0070] see figure 1 , Figure 1A The shown configuration diagram of installing all rods between the dynamic platform 1 and the static platform 2 does not have any degree of freedom, and is for the convenience of expl...

Abstract

The invention discloses a reconfigurable flexible teaching aid for demonstrating the duality relation of freedom degree and restraint in mechanical principle teaching. The teaching aid comprises a movable platform, a static platform and six rod pieces, wherein the six rod pieces are arranged between the movable platform and the static platform. According to the teaching aid designed, on one hand, teaching aid configurations with different freedom degrees can be lapped by utilizing the modularized rod pieces and the platforms, on the other hand, the duality relation between the freedom degree and the restraint can be verified by utilizing the lapped teaching aid configurations. Through the direct observation of the teaching aid, students can directly master the concepts of freedom degree and restraint and the like as well as the duality relation between the concepts.

Description

technical field [0001] The invention relates to a teaching tool, more particularly, a reconfigurable flexible teaching tool for demonstrating the dual relationship between degrees of freedom and constraints in the teaching of mechanical principles. Background technique [0002] The concept of degrees of freedom, constraints, and virtual constraints is very important in the study of mechanical principles, because it is very useful for designers to analyze and design mechanisms. However, concepts such as degrees of freedom, constraints, and virtual constraints are often difficult for beginners to intuitively imagine and understand clearly due to their multidimensional or abstract nature, which brings a lot of trouble to students' learning and teachers' teaching. Contents of the invention [0003] The reconfigurable flexible teaching aid provided by the present invention for demonstrating the dual relationship between degrees of freedom and constraints is assembled to form mu...
