| Abstract: | Dynamic simulation of long jump is intended to analyze key motions in long jump, that is, impacts in takeoff. Simulation equations applied to multi - rigid - body takeoff impact are derived by lagrange impact equations . Main factors affecting results of long jump can be analyzed by these simulation equations. A mathematical model describing transit of long jumpers is constructed, taking distances of long jump as the target function. Optimization parameters of long jump technique can be calculated by computing facilities, which provides a theoretical basis for scientific training to instructors. |
