I. Equipment Introduction

The aircraft landing gear shimmy test device is primarily used to simulate the dynamic characteristics of the landing gear system during aircraft taxiing, takeoff, and landing. By precisely testing the dynamic response of aviation tires and landing gear under disturbance excitation, it provides critical data support for aircraft design and airworthiness certification.

Test Principle:

The landing gear shimmy test is based on recording and analyzing the response of the landing gear after applying transient initial disturbances under simulated aircraft taxiing conditions, verifying the shimmy stability of the landing gear.
