Long Jump

In order to detect the take-off forces of athletes in long jump, a novel force sensor based take-off board is designed. The take-off board consists of a standard take-off board, two novel force sensors, two support plates and a base. The working mechanism of the strain beam in the force sensor is analyzed and the finite element method(FEM) is used to investigate the structural deformation and stress distribution. Then the sensor is tested. The calibration experimental results demonstrate that the sensor has an excellent measurement linearity (0.6%) and can meet the requirements of practical applications. Then the multi-function take-off board based on the force sensors is designed and manufactured which can make the daily long jump training more scientific.

Composite Adaptive Control

In this article, a composite adaptive control method without persistent excitation condition is proposed to improve force tracking performance of an electro-hydraulic loading system. Due to structure restriction, the force sensor cannot be installed and associated force signals are unable to be obtained by the control hardware. Thus, a composite adaptive control method is designed to estimate the unknown spring stiffness and friction coefficient of the electro-hydraulic loading system. Simultaneously, a modified prediction error is designed to relax the stringent persistent excitation condition of the conventional adaptive method. Then the position trajectory of the cylinder could be optimized by using the estimated stiffness to achieve accuracy loading for the specimen. Furthermore, first-order filters are utilized to produce certain virtual controllers and their derivatives to avoid analytic calculation. At last, the stability analysis of the closed-loop system is given, and the comparative experimental results have verified the effectiveness of the proposed control method.

Micro Force Sensor

The current method of micro-force generated for sensor calibration is scarcity and complexity. In the paper we propose a mechanism based on flexible hinges for micro-force, illustrate its working principle and establish the mechanical model. By theoretical analysis the analytical expression of the force reduction multiplier is derived. After initializing some parameters, the result shows that this mechanism can produce the large range and high resolution force of µN. The force can be applied in calibration of micro-force sensor.
