What is a falling ball impact testing machine?
In the fields of industrial production and materials research and development, the falling ball impact testing machine is a common testing equipment used to evaluate the performance of materials or products when subjected to impact. This article will introduce in detail the definition, working principle, application fields and related technical parameters of the falling ball impact testing machine, and discuss its importance in the industry based on hot topics on the entire network in the past 10 days.
1. Definition of falling ball impact testing machine
The falling ball impact testing machine is a testing equipment that simulates impact force through free fall. It usually consists of a height-adjustable bracket, a standard steel ball or impact ball made of other materials, and a data acquisition system. During the test, the ball falls freely from a predetermined height and hits the surface of the sample. The impact force and deformation or damage of the sample are recorded through the sensor.
2. Working principle
The working principle of the falling ball impact testing machine is based on the law of conservation of energy. During the free fall of the sphere, the potential energy is converted into kinetic energy, and an impact force is generated when it hits the sample. The equipment measures parameters such as impact force and displacement through high-precision sensors and generates data reports to help users analyze the impact resistance of materials.
