specific Embodiment approach

[0043] 1. The right end of the working surface on the motion platform IV can fix two rectangular parallelepiped motion platform connecting seats V along the Y-axis direction, and set two sets of No. 3 horizontal force-applying units H along the X-axis direction. The right end surfaces of the two cuboid-shaped motion platform connecting seats V are respectively fixedly connected with one end bolts of the No. 3 force applying unit X III in the two sets of No. 3 horizontal force applying units H arranged along the X-axis direction. The two sets of No. 3 horizontal forces The other end of No. 3 force applying unit X III in the force applying unit H is fixedly connected to the foundation through anchor bolts.

[0044] 2. When two sets of No. 3 horizontal force-applying units H are installed on the right end of the motion platform IV along the X-axis direction, only No. 1 horizontal force-applying unit B or No. 2 horizontal force-applying unit G can be installed along the Y-axis dire...

[0057] 1. No. 1 six-degree-of-freedom motion test platform A is equipped with No. 1 horizontal force application unit B and No. 2 horizontal force application unit G along the y-axis direction, and No. 3 horizontal force application unit is set along the x-axis direction on No. 1 six-degree-of-freedom motion test platform H, to achieve the desired effect.

[0058] 2. When No. 1 six-degree-of-freedom motion test platform A is set along the y-axis direction with No. 1 horizontal force application unit B and No. 2 horizontal force application unit G, No. 1 six-degree-of-freedom motion test platform is set along the x-axis direction with No. 3 The horizontal force applying unit H can be increased to two sets, and the implementation effect remains unchanged.

[0059] 3. Set No. 1 horizontal force applying unit B or No. 2 horizontal force applying unit G along the y-axis direction on No. 1 six-degree-of-freedom motion test platform A (that is, set up a set of horizontal force applyi...

Abstract

The invention discloses a double six degree-of-freedom (DOF) motion testing platform for railway vehicle bogie. In the invention, a No.1 six DOF motion testing platform and a No.2 six DOF motion testing platform are arranged on a foundation symmetrically, wherein the No.1 six DOF motion testing platform or the No.2 six DOF motion testing platform comprises a No.1 horizontal force application unit, a No.2 horizontal force application unit, a No.3 horizontal force application unit, a vertical force application unit, a No.1 holding testing unit, a No.2 holding testing unit and a wheel pair, the lower end of the vertical force application unit is connected with the foundation, the upper end of the vertical force application unit is connected with one end of the No.1 horizontal force application unit and one end of the No.2 horizontal force application unit, the other end of the No.1 horizontal force application unit and the other end of the No.2 horizontal force application unit are connected with the foundation, one end of the No.3 horizontal force application unit is connected with the right end of the vertical force application unit, the other end of the No.3 horizontal force application unit is connected with the foundation, and the No.1 holding testing unit, the No.2 holding testing unit and the wheel pair are fixed on the upper end face of the vertical force application unit symmetrically.

Description

technical field [0001] The invention relates to a rail vehicle bogie parameter testing device, more specifically, the invention relates to a rail vehicle bogie double six-degree-of-freedom motion testing platform. Background technique [0002] At present, the domestic and foreign rail vehicle bogie characteristic parameter test benches are mainly used to test the shear stiffness, bending stiffness and other parameters between the wheel sets of the bogie. It is difficult to integrate these test items into one test equipment to complete. In recent years, German Windhoff Company, American Standard Car Bogie Company (SCT) and ABC-NACO Company, as well as Canadian Bombardier Company have all conducted research on the detection technology of train bogies and proposed corresponding technical solutions and developed bogie parameter test benches. , but in addition to the high price of these devices, the measurement of the vertical, longitudinal and rotational stiffness of the overall...
