System and Method for Tracked Vehicle Dynamometer Testing

摘要

A system and method for tracked vehicle dynamometer testing. The dynamometer system may be configured as a treadmill electric chassis dynamometer having dual, parallel endless belts positioned as substantially flat surfaces with cleats, i.e., the tracks of a test vehicle and a dynamometer vehicle. The track assemblies of the test vehicle and the dynamometer vehicle are generally vertically, mechanically coupled in close contact with each other via a retention fixture. The testing may be conducted in a climatic chamber to simulate various environmental conditions.

主权项

1. A system (100) for tracked vehicle dynamometer testing, the system comprising:
a dynamometer vehicle (50_DYNO) having dynamometer vehicle tracks; a test vehicle (50_TEST) having test vehicle tracks, wherein the test vehicle is similar to the dynamometer vehicle; and a test fixture (120) comprising a base (122), a front retention bracket (140), and a rear retention bracket (160); wherein,
the test fixture (120) vertically, mechanically couples the test vehicle (50_TEST) and the dynamometer vehicle (50_DYNO) together via the front retention bracket (140) and the rear retention bracket (160) such that there is direct, adjacent contact of the test vehicle tracks to the dynamometer vehicle tracks, and the test fixture (120) elevates the dynamometer vehicle (50_DYNO) above the base (122) such that the dynamometer vehicle tracks move freely during the dynamometer testing.
