The standby method for testing many specification accelerometers, can realize and various sizes, profile accelerometer are tested in same test equipment
Product, is greatly lowered the testing cost of accelerometer product.
The technical scheme that uses to achieve the above object of the present invention is：It is a kind of many with the test equipment test of special accelerometer
The method of specification accelerometer, comprises the following steps：(1) appearance and size and installation site chi of accelerometer to be tested are measured
It is very little；(2) switching device is designed：Provided with the outline phase with accelerometer one end to be tested locating dowel in the middle part of switching device
Same center positioning hole, centralized positioning hole peripheral is uniformly placed with the mounting hole I that can be arranged on switching device in test equipment,
Centralized positioning hole peripheral is also uniformly placed with the mounting hole II for installing accelerometer to be tested；(3) will by mounting hole I
Switching device is arranged in test equipment；(4) accelerometer to be tested is installed on switching device and tested：It is to be tested
The locating dowel of accelerometer one end is positioned in the center positioning hole of switching device, and accelerometer to be tested is solid by mounting hole II
It is scheduled on switching device, then treats testing acceleration meter and is tested.
The present invention further technical scheme be：Switching device in the step (2) is generally circular, centralized positioning
Hole is to be arranged on the manhole in the middle part of switching device, the position of mounting hole I and the mounting hole site of each installation position of test equipment
Put corresponding, mounting hole II is corresponding with the position of mounting hole of accelerometer to be tested.
The present invention further technical scheme be：The diameter of the switching device is not more than two neighboring survey in test equipment
Try the distance between installation site.
A kind of method for testing many specification accelerometers of equipment test with special accelerometer of the present invention has following beneficial
Effect：The present invention designs a switching device for accelerometer, and accelerometer is navigated into test equipment by switching device
On, switching device is easily worked, cost is low, it is no longer necessary to for manufacturing special test frock per a newly-designed accelerometer
With purchase special test equipment, in the accelerometer development test of follow-up different sizes and profile, only need to change switching device
The position dimension of center positioning hole and mounting hole II is that may be implemented in test various sizes, profile accelerometer in same equipment
The way of product.
A kind of many specifications of special accelerometer test equipment test of the invention are accelerated with reference to the accompanying drawings and examples
The method of degree meter is further described.
