Abstract
A surrogate component for shock testing is disclosed that includes a housing with exterior dimensions, mass, and a center of gravity approximately the same as the exterior dimensions, mass, and center of gravity of a counterpart component. The housing also has a stiffness greater than the counterpart component and has an interface for securing a sensor. In particular, the counterpart component may be hard drive and the housing may be constructed from a molybdenum material.
Claims20
A surrogate component for shock testing comprising:
- a housing having exterior dimensions, mass, and center of gravity approximately the same as the exterior dimensions, mass, and center of gravity of a counterpart component;
- the housing having a stiffness greater than the counterpart component;
- and
- the housing having an interface operable to secure a sensor.
A system for shock testing comprising:
- a shock table;
- a test system secured to the shock table;
- at least one surrogate component installed within the test system, the surrogate component comprising:
- a housing having exterior dimensions, mass, and center of gravity approximately the same as a counterpart component;
- the housing having a stiffness greater than the counterpart component;
- the housing having a cavity formed therein;
- an accelerometer secured within the cavity;
- and
- a computer operatively coupled to the accelerometer, the digital computer operable to receive and record surrogate component shock data from the accelerometer.
A method for testing a computer system comprising:
- obtaining surrogate component shock data from an accelerometer secured to a surrogate component installed within a test system;
- converting the surrogate component shock data to the shock response spectrum (SRS);
- and
- comparing the surrogate component SRS data to known counterpart component SRS data.
