Force sensor in automotive safety experiment and robot industry application

Speaking of multi-axis load cells, there are not many people who know. However, many people have seen car crash experiments on television, and judged the safety performance of the car by colliding with the output signal of the human sensor. It can be said that without the multi-axis load cell, the collision simulator can only act as a model in the window, and it can't really work.

A load cell is installed on the simulator of the car safety crash test.

Load cell in automotive safety performance test

In the car safety laboratory, the car manufacturer usually conducts safety performance experiments, allowing the simulator to sit in the car, intentionally colliding, and then detecting the acceleration, load and deformation of various parts of the simulator to assess the safety level of the car. .

Most of the simulators are made of metal and plastic, not only have the same shape as real people, but also complex spine, ribs and synthetic muscles. Most importantly, the simulator is equipped with a variety of multi-axis load cells for the technician to analyze the technical data of the car at the moment of collision. In general, multi-axis load cells are mounted on different parts of the neck, hand, and legs of a car crash simulator.

The neck will be broken by a certain degree of force, and the thigh will be fractured by violent impact. By analyzing the various force data collected by the load cell and the dummy's 'injury', the car manufacturer can assess the safety performance level accordingly.

Existing exploration of load cells in the robot industry

In addition, at present, domestic teams have applied multi-axis load cell technology to the robot industry, which has improved the intelligence level of robots.

How can robots be smarter, one with vision and the other with touch. At present, 95% of the robots have so-called vision. If a multi-axis load cell is added, the robot's hand is perceived, which greatly enhances the robot's intelligence.

In addition, the multi-axis load cell can also be used in industrial applications such as ordinary metal parts such as sanding, such as sanding work, which is more demanding for tactile robots. In the grinding work, dust is harmful to the human body, work intensity is high and safety accidents occur frequently. At present, a domestic team is also planning to develop intelligent grinding heads with multi-axis load cells, allowing robots to replace manual grinding, so that more companies can use it.
