Abstract

The invention relates to a load test device for a rotary hinge device. The device is used for testing the mechanical property of the rotary hinge device, and comprises a platform, a bracket, bidirectional loading devices, a horizontal loading device and vertical loading devices, wherein the bracket is vertically arranged on the platform; the bidirectional loading devices are configured to simultaneously provide test loads from both vertical and horizontal directions; the horizontal loading device is arranged on the platform; the vertical loading devices are arranged on the bracket; in a working state, the vertical loading devices are connected with a first fixing seat of the rotary hinge device; and the horizontal loading device is connected with a second fixing seat of the rotary hinge device. The device applies loads in two directions at the same time to simulate the stress situation when the rotary hinge device is mounted on a vehicle for driving, so that the mechanical property ofthe rotary hinge device is accurately measured.

Description

technical field [0001] The invention relates to a load test device for a rotary hinge device, in particular to a device for testing the mechanical properties of a rotary hinge device. Background technique [0002] 100% low-floor light rail vehicles are recognized and used by many cities around the world due to their economy, environmental protection, aesthetics and comfort. Since the world's first low-floor light rail vehicle was officially put into operation, with the continuous development and application of new technologies, foreign urban light rail vehicles have entered the era of different types of 100% low-floor vehicles. With the development of my country's modern society and economy, my country's urban traffic has higher and higher requirements for rapidity, low energy consumption, energy saving and emission reduction. There is also a growing demand for 100% low-floor light rail vehicles. [0003] Between the carriages of 100% low-floor light rail vehicles, in addi...
