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...

Abstract

The invention provides a vehicle end relation comprehensive test stand applicable for an interference test, a function test and a research test of a vehicle end relation component based on a six-degree-of-freedom parallel mechanism. A front counter-force base is fixed to a foundation, and connected with six sets of hydraulic execution mechanisms through three groups of low hinging supports; the front ends of the hydraulic execution mechanisms are connected with a motion platform through three groups of upper hinging supports; the motion platform is connected with an air spring through a bracket; the other end of the motion platform is connected with a front end transitional plate through a connecting frame; and a six-dimensional force / torque sensor is arranged on the motion platform. By adopting a modularized flexible design, the test on all members on the vehicle end of a railway carriage can be performed by adjusting the combinations of different members or a single member on the vehicle end, states of a train which runs through a straight line or a curve can be simulated, and a mutual interference relation of the members on the vehicle end can be checked; and the function test and the research test can be performed. The vehicle end relation comprehensive test stand is applicable for a motion simulation test and a force loading test of other large structural members.

Description

(1) Technical field [0001] The invention relates to electromechanical technology, specifically a comprehensive test bed for vehicle-end relations. (2) Background technology [0002] With the advent of the era of high-speed rail, the speed of trains continues to increase, which puts forward higher requirements for the design of train components. Car-end components are key components of high-speed trains and are crucial to ensuring the overall performance of the train. As the core component of the car-end components, the through-channel is also the focus of the design. This requires a set of high-performance comprehensive test equipment, which can not only realize high-precision motion simulation function, but also have high-precision force loading function to meet the motion interference test, functional test and research of vehicle-end related components. The test requirements provide reference for the design of train components. But at present there is no special equipme...
