[0054] Example 1

[0055] In this embodiment, the door opening process of the door system is taken as an example to illustrate the simulation process of the present invention.

[0056] In the ADAMS simulation environment, the external load is set to 75N resistance, which acts horizontally on the door panel 1 (opposite to its movement direction), the motor drive parameter is 205r / min (forward rotation), and the contact parameter setting of the rolling lock pin 2 is shown in Table 1.

[0062] In this embodiment, the door closing process of the door system is taken as an example to illustrate the simulation process of the present invention.

[0063] In the ADAMS simulation environment, set the external load, motor drive parameters, and the contact parameters of the rolling lock pin 2. Among them, the external load and the contact parameters of the rolling lock pin 2 are the same as those set in Embodiment 1, and the motor driving parameter is 50 r / min (reverse rotation). Under the above parameter settings, the simulation results of the displacement, velocity, acceleration and force of the rolling lock pin 2 are as follows Figure 7 ~ Figure 10 Shown. From Figure 7 ~ Figure 10 In the door system closing process, the locking device, especially the movement and force of the lock pin 2 can be deeply understood, and a conclusion similar to the above-mentioned door opening process can be drawn from this: that is, the rolling lock pin 2 and the scr
