Embodiment Construction

[0042] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0043] This embodiment determines the design parameters of a comprehensive environmental test chamber for the brake system of a civil aircraft. Comprehensive stress test. The design parameters of the test chamber include:

[0044] High temperature range; low temperature range; heating and cooling rates under load conditions; temperature protection design for the brake system; structural design. In order to meet the test requirements of the brake system, the mean time between failures (MTBF) of the comprehensive environmental test chamber is 5000h.

[0045] see figure 2 , the specific process of this embodiment is:

[0046] Step 1, determine the temperature design parameters of the comprehensive environmental test chamber

[0047] The first step is to determine the high temperature design parameters of the comprehensive environmental te...

Abstract

The invention belongs to the field of civil aircraft brake system environment test equipment development, and relates to a design method of a civil aircraft brake system comprehensive environment testbox. The design method comprises the steps that the temperature design parameter of the comprehensive environment test box is determined; design of the high temperature protection function is performed on the brake system; the structural design of the comprehensive environment test box is determined; and reliability testing of the comprehensive environment test box is performed so that whether the requirement of mean time between failures MTBF=5000h is met can be determined. The reliability of the comprehensive environment test box is enhanced so that waste of resources and energy caused by frequent replacing of the comprehensive environment test box can be avoided and the pollution to the environment can be reduced.

Description

technical field [0001] The invention belongs to the field of development of civil aircraft braking system environmental test equipment, and relates to a design method of a civil aircraft braking system comprehensive environmental test box. Background technique [0002] The temperature test of the conventional aircraft brake system adopts the method of independently conducting each product item by item. Domestic and foreign users directly purchase standard comprehensive environmental test chambers according to the routine, and the design parameters for special purposes are not mentioned in the procurement process, the derating design method is not clearly adopted, and the reliability indicators of the comprehensive environmental test chambers are not tested. Frequent equipment failures occurred during use, which affected the normal progress of product tests. [0003] The environmental test standards represented by the US standard DO-160 "Environmental Conditions and Test Pro...
