AI Technical Summary

Technical Problem

Existing technologies make it difficult to measure the parachute line load during the parachute pack pulling process under simulated real-world conditions, which affects the stability and reliability of the parachute.

Method used

A parachute opening friction test platform was designed, including a drive loading mechanism, a parachute line traction mechanism, a friction tool fixing mechanism, a sensor trolley mechanism, and a buffer unloading mechanism. The parachute line is driven by an asynchronous motor to perform variable acceleration linear motion, and the tension, speed, and friction of the parachute line are measured by combining a tension sensor and a pull wire encoder.

Benefits of technology

It enables precise control and data measurement of parachute lines during parachute deployment, provides a reliable experimental environment, lays the foundation for parachute design and optimization, and improves the stability and reliability of parachutes.

Abstract

This invention discloses a parachute opening friction test platform, comprising a test platform frame, a drive loading mechanism, a parachute line traction mechanism, and a steel cable; the drive loading mechanism includes an asynchronous motor and a traction roller; the parachute line traction mechanism includes a friction force fixture fixing mechanism, a sensor trolley mechanism, a limit switch, and a buffer unloading mechanism; the friction force fixture fixing mechanism limits the parachute lines; the tension sensor and safety release mechanism of the sensor trolley mechanism are respectively fixed on a slider plate, the slider plate is slidably connected to a ball bearing rail, the end of the parachute lines is connected to the tension sensor, the safety release mechanism is connected to one end of the steel cable, and the other end of the steel cable is wound around the traction roller; the buffer unloading mechanism is used to decelerate the sensor trolley mechanism and allow the steel cable to continue moving when it collides with the safety release mechanism; the limit switch is located on one side of the sensor trolley mechanism to control the asynchronous motor of the drive loading mechanism to stop.
