Embodiment 1
[0009] Example 1: Combining figure 1 , the present invention is a comprehensive test bench for car-end relationship, which is composed of front reaction force foundation (1), lower hinge support (2), hydraulic actuator (3), motion platform (4), upper hinge support (5 ), connection frame (6), air spring (7), front transition plate (8), bracket (9), six-dimensional force / torque sensor (10), through channel (11), rear transition plate (12) , the simulated compartment end (13), and the rear reaction force foundation (14) are formed. The front reaction force foundation (1) is fixed to the foundation, connected with six sets of hydraulic actuators (3) through three sets of lower hinge supports (2), and the front end of the hydraulic actuator (3) is passed through three sets of upper hinge supports (5) It is connected with the motion platform (4), the motion platform (4) is connected to the air spring (7) through the bracket (9), and the other end of the air spring (7) is connected ...
Embodiment 2
[0010] Example 2: Combining figure 1 , figure 2 , the present invention has the following technical characteristics:
[0011] 1. Based on the positive kinematics solution of the six-degree-of-freedom parallel mechanism, it can realize high-precision pose measurement;
[0012] The kinematics of the six-degree-of-freedom motion system describes the relationship between the motion of the drive system and the motion of the motion platform. Knowing the motion of the motion platform, finding the motion of the driving system is called the inverse kinematics solution (inverse solution); conversely, knowing the motion of the driving system, and finding the motion of the moving platform is called the forward kinematics solution. Since the motion platform of the motion system is fixedly connected with the through passage, the movement of the motion platform is consistent with the movement of the through passage.
[0013] At present, there is no special instrument at home and abroad t...
