Steady-state acceleration test of electrical and electronic products

The purpose of the steady-state acceleration test is to simulate the effects of steady-state acceleration experienced by samples mounted on rotating parts, projectiles and operating vehicles, especially space vehicles. The steady-state acceleration test of electronic and electrical products is used to determine whether the structural adaptability and performance of components, equipment and other electrical and electronic products are good under the force (except gravity) generated by a steady-state acceleration environment, such as the force generated by running vehicles, aerial vehicles, rotating machinery and projectiles, as well as to evaluate the structural integrity of some components.
Zhongke Testing Reliability Experiment Center has environmental testing capabilities for various electrical and electronic products, and provides professional steady-state acceleration test services for electrical and electronic products.

When a centrifuge is used to generate steady-state acceleration, the direction of acceleration is toward the center of the rotating system. In some special cases, where only a machine capable of producing linear acceleration can be used to carry out the test because some samples may be sensitive to gyratory couples, the relevant specifications should state this.
1) Tangential acceleration When the speed of the centrifuge increases from zero to a specified value, or decreases from a specified value to zero, the centrifuge should be controlled so that the tangential acceleration experienced by the sample is not greater than 10% of the specified steady-state acceleration value.
2) Acceleration Gradient The centrifuge should be sized relative to the sample so that no part of the sample (except the dangling leads) is subjected to tolerances exceeding the specified steady-state acceleration value.
3) Acceleration tolerance: If the linear dimension of the sample is less than 10 cm, any part of the sample (except the suspended leads) should be within ±10% of the specified steady-state acceleration value. In other cases, the specified steady-state acceleration tolerance is -10%~+30%.
