Embodiment
[0031] Such as figure 1 As shown, a load simulation device for a power cabin includes a mechanical platform, a loading module, and a computer monitoring system, which can realize simulated loading of the engine and gearbox assembly.
[0032] The mechanical table body consists of a cast iron platform and several different types of brackets. The cast iron platform is used as the base, and the types of brackets include power cabin brackets, eddy current dynamometer brackets, bearing brackets, and torque speed sensor brackets. The cast iron platform fixes the power cabin, bracket and loading module through flanges. The mechanical table body provides an installation basis for the whole set of equipment, and at the same time, it can also reduce the vibration of the engine and gearbox during operation.

The invention relates to a load simulation device and method for a power cabin and belongs to the technical field of automatic detection. The load simulation device comprises a mechanical table, a loading module and a computer monitoring system. An electric eddy current dynamometer is adopted for simulating loads of the power cabin in different terrains and under different working conditions, actual working loads of the power cabin effectively reoccur, and the defects that the difficulty that the power cabin needs to be subjected to a road driving test after being installed on a vehicle, so that test efficiency is low, test cost is high, and maintenance is difficult after problems occur are avoided. A double closed-loop plus feedforward control strategy is adopted, various loads can be provided precisely according to settings without the influences of the rotating speed and the rotating direction, the accuracy of test conditions is guaranteed and loading effectiveness is improved through a two-dimensional load simulation strategy and a synchronous control strategy, and the load simulation device and method are suitable for relevant fields such as production and maintenance of armored vehicles.
Description
technical field [0001] The invention relates to a load simulation device and a simulation method of a power cabin, belonging to the technical field of automatic detection. Background technique [0002] The main purpose of the power cabin load simulation is to provide the same test conditions as the actual working conditions when fully testing the performance of the power cabin. Specifically, after the power cabin is assembled but before it is loaded into the vehicle, the load simulation device is used to simulate the loading and running conditions of the power cabin, and to test the relevant parameters in the system and the sealing of the system to test its working performance. [0003] The power cabin load simulation device is mainly composed of a mechanical platform (including cast iron platform, various types of brackets), a loading module (eddy current dynamometer and controller, torque speed sensor, power cabin cooling system) and a computer monitoring system. The simu...
