Design and Application of Environmental Worthiness of Onboard Oxygen Generator for Special Vehicles
The work aims to conduct environmental worthiness design to the onboard oxygen generator of special vehicles,so that the generator can meet the function and performance requirements in the plateau environment,complex electromagnetic and special environment.Based on the analysis of the working requirements and the environmental impact factors of the on-board oxygen generator,the comprehensive environmental worthiness design of the onboard oxygen generator in low pressure,high and low temperature,wet and hot,vibration and shock,and complex electromagnetic environment wascarried out by adopting the key technologies of air compression pump mass displacement compensation,efficient heat dissipation and cool-ing,comprehensive shock absorptionand electromagnetic compatibility and then verified by the test.The onboard oxygen gen-erator had an oxygen productionof 3.41 L/min and an oxygen concentration of 56.7%at a simulated altitude of 4 500 m andan oxygen production of 3.30 L/min and an oxygen concentration of 51.8%in the plateau environment of 5 200 m.The generator could work normally in high and low temperature environment,with oxygen output.The surface was not damaged,the function was normal,the oxygen production was greater than 3 L/min,the oxygen concentration was more than 90%in wet and hot and vibration and shock environment.The electromagnetic compatibility met the requirements of GJB 151B—2013"Requirements and Measurement of Electromagnetic Emission and Sensitivity of Military Equipment and Subsystems"for army ground equipment and satisfied the requirements of electromagnetic compatibility for real vehicles.The environmental worthiness de-sign method for the onboard oxygen generator is effective and can meet the relevant standards.
