Abstract
The invention provides a combustion chamber ignition test working condition optimization method. The method comprises the following steps: step 1, establishing a combustion chamber lean oil ignition boundary estimation reference model; 2, establishing a lean ignition boundary fitting formula of the combustion chamber on the basis of discrete test data and the lean ignition boundary estimation reference model of the combustion chamber; 3, an ignition boundary is calculated to form a super-space curved surface, an original working condition set in the space is formed, and boundaries corresponding to working condition points in the original working condition set are discrete points distributed on the super-space curved surface; and 4, performing ignition test working condition optimization on the original working condition set to form an optimized working condition set, and determining a final working condition set according to the ignition boundary deviation requirements of the original working condition set and the optimized working condition set. According to the combustion chamber ignition test working condition optimization method, the test working conditions can be greatly reduced, and the test efficiency is improved.
