Environmental Vibration Testing Battery Shaker Vibration Testing System 3000Hz
Equipment overview
Environmental Stress Screening (DCS) is extremely effective in eliminating potential product defects. In the development stage, it becomes a magic weapon to find product design defects to achieve reliability growth; in the production stage, it becomes an important means to reduce production costs and create excellent products.
The DCS project will be applied during product development and production, which can greatly improve product reliability and reduce maintenance costs. Applying DCS during development can greatly save testing time and cost, thereby eliminating or reducing hidden defects before testing. The benefits for producers include: insight into reliability problems in products or processes, so as to eliminate reliability problems from products and processes, reduce production costs and save resources.
Vibration test can be used to find early battery failure, simulate actual working condition assessment and structural strength test. The product has a wide range of applications, wide application range, remarkable and reliable test effect. It is an ideal battery-specific vibration test for battery manufacturers, quality inspection departments and research institutes. Test Equipment. It is suitable for vibration testing of various types of single cells and battery packs such as charging treasures, lithium-ion, nickel-metal hydride, nickel-cadmium, lead-acid, and nickel metal hydride.
Vibration tests can also be used for fatigue tests of products for life assessment of products.
