Plastic runway impact absorption testing machine

1、 Equipment Overview:

The plastic track impact absorption testing machine is mainly used for testing the impact absorption performance of plastic sports fields. The machine's heavy hammer simulates the effect of human action on the impact synthesis surface layer, and the test results are calculated through a computer system.

2、 Technical principle:

The basic theory is to drop a heavy hammer of a specified mass from a specified height according to the law of conservation of energy, converting potential energy into kinetic energy. The converted energy impacts the test sample, and the force value is sampled and transmitted to a computer acquisition system through an impact sensor. The computer then performs a series of processes such as sampling, processing, calculation, and analysis to display the results of impact absorption and vertical deformation acting on plastic composite materials, thereby measuring the impact resistance and deformation parameters of plastic materials.

3、 Execution standards:

According to the requirements of BS EN14808-2005 "Determination of Impact Absorption of Ground Layers in Sports Fields", GB36246-2018 "Draft for Comments on Synthetic Material Surface Layer Sports Fields for Primary and Secondary Schools" - Appendix B and Appendix C, GBT 14833-2011 "Synthetic Material Runway Surface Layer", GB/T 22517.6-2011 "Requirements and Inspection Methods for the Use of Sports Fields Part 6: Track and Field Fields", GB/T 19851.11-2005 "Sports Equipment and Fields for Primary and Secondary Schools Part 11: Synthetic Material Surface Layer Sports Fields", and GB/T 19995.2-2005 "Requirements and Inspection Methods for the Use of Natural Materials Sports Fields Part 2: Wooden Flooring Fields for Comprehensive Sports Venues".
