Load control system and load control method of dynamic performance test stand of monorail bogie

Abstract

The invention discloses a load control system and a load control method based on a dynamic performance test stand of a monorail bogie. The control system comprises a load motor, a transducer, testing devices such as a temperature raising apparatus, a torquemeter and the like, and a control system, wherein bogie walking wheels are connected with the load motor through the torquemeter and a coupler; a temperature testing apparatus is connected with a gear box and a shaft box bearing; the control system is in communication connection with the whole set of equipment; and the control system adjusts states of the bogie according to data fed back by testing equipment so as to test relevant data of the bogie in various states. Through the system and the method provided by the invention, the test of the rotation speed and torque of the bogie walking wheels in various states is controlled by the transducer; and data such as traction, a brake performance curve, an acceleration and deceleration speed, brake time, brake force, a brake distance and the like of the bogie are obtained through a self-developed algorithm, so that the test of various performances in the bogie walking wheels load are realized; the safety and the reliability of the bogie are improved; and the system plays an important role of breaking the abroad monopolization to relative technologies of the bogie.

Description

technical field [0001] The invention relates to a bogie load control system and method, in particular to a load control system and method for a monorail bogie dynamic performance test bench in monorail railway applications. Background technique [0002] Since 2005, my country has built a straddle-type monorail transportation system for the first time, which has greatly promoted the establishment of my country's modern urban passenger transportation system. Although my country has introduced related vehicle technologies from abroad, some core equipment and technologies still rely on foreign countries. Independent research and development The localization of monorail transportation equipment related to core technologies can greatly reduce construction costs, and bogies must undergo special testing before leaving the factory. The independent research and development of bogie testing equipment will help my country realize the localization of monorail transportation equipment can p...

AI Technical Summary

Problems solved by technology

Based on conventional bogie test benches such as figure 1 As shown (traditional bogie test rig), the bogie test rig includes load motors, bogies and related electronic components, and has the following disadvantages: a. The experimental data obtained by the bogie test rig only includes the bogie running at a certain speed The relevant characteristics, carrying capacity and load of the wheel, b. The waste of electric energy during the test is also extremely huge

Therefore, the existing bogie test bench cannot meet the more accurate and wider test data and items required by the increasing development of monorail transportation equipment, and cannot cope with the increasingly tense world situation of energy

[0004] Therefore, the problems of narrow coverage and large energy consumption of traditional bogie test benches must be solved
