OBJECTIVE: To study the thermo-dynamic model of a combustion-bouncing bounce actuator, analyze the output performance of a driver, and verify the correctness of the thermo-dynamic model of the drive by experiments. Innovative points: 1. The thermal-dynamic model of the bombshell bounce actuator was established, and the variation law of the related output parameters of the bombshell bouncing actuator over time was obtained.2. The output performance of the driver was analyzed by theoretical simulation and test. Based on the analysis of working process of the bombshell bouncing robot, the dynamic model of the bombshell bouncing actuator is deduced, and the locking force and spring stiffness parameters are tested.2. According to the thermo-dynamic model The pressure in the combustion chamber changes with time as a function of time.3. The test results are compared with those of the thermo-dynamic model by testing the curve of pressure and displacement with time during the drive-driven bouncing process. The conclusion is as follows: 1. The thermo-dynamic model of combustion-explosion bounce actuator is established, and the output performance parameters of the actuator are obtained.2. The experimental results are in good agreement with the simulation results, which proves the correctness of the thermo-dynamic model.
