Abstract

The invention provides a lateral force and lateral restoring moment measuring instrument for a ship model. The lateral force and lateral restoring moment measuring instrument comprises a main sliding unit, a secondary sliding unit, an automatic unloading unit, a bearing unit and an angle adjusting unit, wherein the upper and lower sides of an airworthiness instrument are provided with an upper mounting plate and a lower mounting plate, and the upper end of the main sliding unit is connected with the airworthiness instrument through the upper mounting plate and the lower mounting plate; the upper end of the secondary sliding unit is connected with the airworthiness instrument through the upper mounting plate and the lower mounting plate, and the lower end of the main sliding unit is connected with the bearing unit; the lower end of the bearing unit is connected with the angle adjusting unit, and the lower end of the secondary sliding unit is connected with the automatic unloading unit. The lateral force and lateral restoring moment measuring instrument provided by the invention has the advantages that the required precision can be ensured in the complicated environment engineering and test environment, and the multi-cycle and long-time measurement requirement can be met.

Description

technical field [0001] The invention relates to a force and torque measuring instrument. Background technique [0002] At present, with the wide application of measuring instruments for measuring forces and moments in tests and engineering practices, the accuracy and durability of the measuring instruments in complex and even harsh environments are particularly important for the measuring instruments. [0003] In the ship model roll test, the test environment is more complicated, and the number of measurement tests and the accuracy have certain requirements. If the general measuring instrument cannot guarantee the accuracy and durability in this complex environment, it will affect the test results, the complexity and the cost to varying degrees. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to provide a ship model lateral force and lateral restoring moment measuring instrument that can still ensure the required accuracy under complex environmen...
