Force effect tester

Abstract

The invention provides a force effect tester. The force effect tester comprises a base, slide guide rails which are symmetrically arranged on the base, a slide end which is fixed on the slide guide rails, a motor mounting rack which is fixed at the slide end, and a tensile force tester which is connected with the slide end, wherein a test circuit board with an onboard master control single chip microcomputer is arranged on the motor mounting rack; the single chip microcomputer is used for testing integral voltage and current through a sensor with a power supply plate, reading results of the tensile force tester, calculating the force effect by combining various results according to the set program, and displaying and recording the force effect on the single chip microcomputer and a display device thereof; the test circuit board 5 further can be connected with a remote-control receiver to supply power to the receiver, and a control signal of the receiver can be connected to control power transfer.

Description

Technical field [0001] The invention relates to a testing instrument, in particular to a testing instrument for measuring the overall force efficiency of a motor and a propeller, belonging to the field of testing instruments. Background technique [0002] In the development process of electric aircraft, the flight efficiency needs to be calculated. Therefore, it is necessary to detect and obtain a key parameter-power efficiency. Power efficiency is used to measure the indicator between power consumption and execution efficiency, which can be directly used to calculate flight time. In order to obtain power efficiency, it is necessary to use a professional instrument for testing the efficiency of the electric power system, that is, a power efficiency test instrument. [0003] The existing force effect test method is to directly connect the blades to be tested to the motor fixing plate in the motor fixing barrel, and install a pressure sensor on the motor fixing barrel, the motor fix...

AI Technical Summary

Problems solved by technology

Since the motor fixing plate is not properly fixed, the torque of the propeller and the motor will have a lateral impact on the motor fixing plate, thereby further affecting the signal acquisition of the pressure sensor. At the same time, due to the need to overcome the flexible force of the bracket, the pressure sensor Difficulty obtaining accurate pressure values

[0004] The existence of these problems makes it difficult for existing force sensors to accurately measure the force parameters of electric aircraft
