The goal of theoretical research is to establish parameters, which have to be given in standards for percussive tests of products. Those parameters are essential for each user to be able to construct identical (equivalent) testing equipment. This would ensure identical results for identical products.The paper presents a detailed analysis of the distribution and the value of the forces generated during percussive collisions of two bodies. Elastic, plastic, and elastoplastic collisions are considered. Parameters determining the coefficient of restitution, the courses of energy, momenta, and the values of the forces in colliding elements are determined. The dynamic force acting on a product during a percussive test was studied. 相似文献

The paper presents a review of head injury criteria and determines an assessment criterion for test results. Parameters characterizing the protection properties of off-central impacted industrial helmets are chosen and the test stands used in the Central Institute for Labour Protection to test those parameters are presented. The idea of damping 2 selected industrial helmets used in Poland is discussed. The test results of the parameters characterizing the protection properties are compared for damped and not damped helmets. 相似文献
