Embodiment
Embodiment one
The dynamic experiment dolly of present embodiment such as Fig. 1-shown in Figure 5, comprise fairshaped car body 1 and the wheel 2 that is loaded on the car body 1 bottom axletree 20.The front and back ends of car body 1 bottom forms front bevel 3 and the back bevel 4 that upwarps respectively, and front bevel 3 and back bevel 4 form angle with surface level respectively, and these angle number of degrees are 5 °-30 °.The front end upper surface of car body 1 is made cambered surface.
As shown in Figure 6, three cavity 5-1,5-2,5-3 before, during and after setting up separately in the car body settle force transducer probe 6 in the preceding cavity 5-1, and an end that is fixed on force transducer probe 6 passes the first through hole 7-1; Settle displacement sensor probe 8 in the cavity 5-2, displacement sensor probe 8 is positioned at the second through hole 7-2 top of offering the car body bottom, and the second through hole 7-2 is waist shape (as Fig. 3); Settle temperature sensor probe 9 and 3-axis acceleration sensor probe 10 in the back cavity 5-3,3-axis acceleration sensor probe 10 can be surveyed dolly at the size and Orientation of doing any motion (as rectilinear motion, circular motion, spiral motion, simple harmonic oscillation etc.) brief acceleration.In cavity, be fixed with the integrated circuit plate, the conversion and the amplifying circuit of force transducer probe 6, displacement sensor probe 8, temperature sensor probe 9 and 3-axis acceleration sensor probe 10 are integrated on the integrated circuit plate, are provided with wireless transport module on the integrated circuit plate.
As Fig. 2 and shown in Figure 6, be shaped on rectangle cavity 11 at car body 1 top, can be used for adding loads, sensor or other experiment annex.
As shown in Figure 6, spring 21 is housed on axletree 20.
Shown in Fig. 1,2 and 3, car body 1 rear end face is made the plane.
As Fig. 2, Fig. 4 and shown in Figure 5, be equipped with screw at headstock (car body 1 front end), the tailstock (car body 1 rear end), cavity 11 and roof (car body 1 top), in order to make things convenient for experiment annexes such as fixation hooks, fixed bar.
First kind of teaching demonstration that uses that the dynamic experiment dolly of present embodiment carries out or experiment are as shown in Figure 7, the wheel 2 of the dynamic experiment dolly of present embodiment is stuck on the depression orbit of straight guide 12, like this, can probe at the uniform velocity or the teaching demonstration or the experiment of even change speed linear motion rule.
Second kind of teaching demonstration that uses that the dynamic experiment dolly of present embodiment carries out or experiment are as shown in Figure 8, the photogate sensor 14 that has pulley 13 is fixed on the wide L type support 15 of straight guide 12, then a bungee 16 and a cord 17 are tied, cord 17 connects car body 1 and walks around pulley 13, and an end of bungee 16 connects force transducer 26.The teaching demonstration or the experiment of the merit of many relation, bonding forces of probing into the momentum of bonding force and relationship with acceleration, bonding force and momentum change with the combination teaching instrument that like this, can use present embodiment and the mechanics phenomenons such as relation of kinetic energy change.
