Real vehicle power load test system and method for power device of tracked vehicle

Abstract

The invention discloses a real vehicle power load test system and method for a crawler-type vehicle power device. The real vehicle power load test system comprises a signal adapter, a data acquisition module, a wireless torque test device, a comprehensive acquisition instrument and a camera, wherein the data acquisition module is installed in a cockpit and receives the video information of the camera and switching data of the signal adapter; the signal adapter is connected with the comprehensive acquisition instrument; the camera is mounted at a set position of a vehicle head, and the signal adapter is arranged in a power cabin, receives the information acquired by the comprehensive acquisition instrument and transmits the information to the data acquisition module; the system solves a problem that the dynamic load cannot be obtained due to limited space of the special vehicle and inconvenient installation of equipment.

Description

technical field [0001] The invention relates to the technical field of vehicle engineering, in particular to a real vehicle power load testing system and method for a crawler vehicle power device. Background technique [0002] The power unit is the power core of the tracked vehicle, and its performance directly affects the maneuverability of the tracked special vehicle. At present, the performance verification of the power unit of tracked special vehicles is limited to the completion of steady-state tests such as thermal balance capability and traction characteristics on the bench, while the overall performance of the power unit, especially the dynamic characteristics, still depends on the field test of the whole vehicle. The rapidly changing dynamic power loads of real vehicles cannot be simulated. Due to the lack of real vehicle dynamic load data, during the development and development of tracked vehicles, the failure modes and faulty parts exposed by the bench test are i...

Problems solved by technology

[0003] In view of this, the present invention provides a real vehicle power load testing system and method for a tracked vehicle power device, aiming at the fact that the dynamic power load of a real vehicle cannot be simulated rapidly when the tracked vehicle is dynamically tested on a bench, which in turn causes The failure modes and faulty parts exposed by the bench test are inconsistent with the actual problems; and due to the limited space, some performance parameters of the power plant cannot be obtained, and the overall performance of the integrated crawler vehicle power plant cannot be fully verified by relying solely on component tests , which brings about a series of problems such as insufficient performance verification of the tracked vehicle power plant, lower than expected vehicle comprehensive performance, and high failure rate, and can obtain the actual dynamic power load of the tracked vehicle
