Environmental adaptability requirements

Temperature	Operating temperature		-40℃ ~ +60℃
	Storage temperature		-45℃ ~ +70℃
Humid heat	Relative humidity		95% ± 3%
	Temperature		+25°C±2°C
	Storage time		72h
Vibration	Vibration spectrum shape (grms=6.06)		20Hz to 80Hz			+3dB/oct
			80Hz to 350Hz			G2/0.04 Hz
			350Hz to 2000Hz			-3dB/oct
	Vibration direction and time		vibrate in two direction for at least 10min. (vibration in two direction i.e. x axis that is along the laser axis and z direction too)
	Control point		should be selected in the fixture or shaking table surface near the maximum stiffness of the product, large equipment can use multi-point average control
	Monitoring point		the monitoring point should be selected in the key part of the product under test, so that the root mean square acceleration response does not exceed the maximum allowable design (grms=6.06)
	Installation requirements		The specimen is firmly attached to the shaking table, and for products equipped with shock absorbers, the shock absorbers should be removed before testing
	Performance check		During vibration testing with the equipment powered on, all performance indicators must meet the technical requirements specified in the design document. In the event of a failure, repairs are allowed. After the repair, the spectral value should be reduced to 0.01g²/Hz, grms=3.03, and the specimen should be subjected to vibration in the direction most susceptible to vibration for 10 minutes during the acceptance test.
Temperature cycle	Temperature range		Power-on test		-40±3℃ ~ +55±2℃
	Rate of temperature change		Temperature rise		10℃/min
			Cooling		10℃/min
	Cycle times		Ten cycles should be completed, ensuring that the last 2 cycles are without faults. If a fault occurs during the last 2 cycles, after repairs, an additional 2 fault-free cycles are required.
	Cycle time		One cycle time is 4h, one cycle includes temperature rise → temperature stay → cooling → temperature stay → temperature rise
	High and low temperature residence time		the residence time depends on the heat capacity of the specimen. Based on the principle of product thermal or cold permeability, the internal temperature of the specimen is maintained for 5min after reaching stability
	The requirements of the product under test		general temperature cycle test with the whole machine, should be as far as possible to open the cover
	Check and repair		In the power test equipment, after each temperature cycle test, it is necessary to confirm that the equipment is free of faults before proceeding to the next temperature cycle
Drenching requirements	Drenching is carried out with the whole equipment
transportation requirements	Equipment needs to be transported as a whole vehicle
	If the product has not undergone a road transport test, you can perform an indoor transport simulation test using a simulation transport table. This test involves conducting a sinusoidal cyclic vibration test to assess the product's performance
	The requirements of the simulated transport table test are as follows
	Test conditions	Frequency		5Hz ~ 200Hz
		Amplitude		5Hz ~ 7Hz
		Amplitude 12mm ~ 8mm
		7Hz ~ 200Hz equal acceleration 1.5g
		Vibration test condition allowable deviation is the same as broadband random vibration test
	Direction	vertical axle direction and side;Orientation: vertical and lateral to the axle
	Cycle time	log-scan 5Hz ~ 200Hz ~ 5Hz, 12min per cycle;When the resonant frequency of the specimen is measured below 5Hz, the test frequency can be extended to 2Hz, 2Hz ~ 200Hz ~ 2Hz scanning, scanning time should be 15min.The vibration time in each direction is 90min
	After the transportation test, check for any signs of damage or structural loosening, and conduct an inspection of technical indices to ensure they meet the design requirements
