Embodiment Construction

[0027] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0028] This embodiment provides a real vehicle power load test system and method for a tracked vehicle power device, aiming at that when a tracked vehicle is dynamically tested on a bench, it is impossible to simulate the rapidly changing dynamic power load of the real vehicle, which causes the bench test The exposed failure modes and faulty parts are inconsistent with the actual problems; and due to limited space, some performance parameters of the power plant cannot be obtained, and the overall performance of the integrated tracked vehicle power plant cannot be fully verified by relying solely on component tests. The actual dynamic power load of tracked vehicles can be obtained for a series of problems such as insufficient performance verification of tracked vehicle power units, lower than expected comprehensive vehicle performance, and high failure rate....

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...
