KRD50 & KRD51 Transportation Simulation Testing Machine Bounce testing

Product catalog summary

Introduction
Bounce testing is crucial for simulating the conditions experienced by cargo during truck transport, especially for military and civilian hardware. This ensures that items such as medical supplies, electronics, and weaponry maintain functionality upon arrival.

Testing Standards
The International Safe Transit Association (ISTA) has developed procedures resembling military tests, such as 1A for products under 150 lb and 1B for those over 150 lb. These tests, along with MIL-STD-810, simulate repeated vibration over distances up to 150 miles.

Technical Specifications
Mechanical Testing Solutions by CME Technology Co., Ltd.
The KRD50 series simulates road conditions like shocks and vibrations to evaluate the impact on goods during transport. It uses a subband approach to simulate broadband random vibration, with adjustable acceleration factors and AC variable frequency control.

Parameters
The KRD50 series offers various models with different specifications:

Max Load: Ranges from 200 kg to 6000 kg
Temperature Range: 0 to 40°C, Humidity ≤ 80%
Simulated Truck Speed: 20 to 80 km/h
Working Table Size: Varies from 1500×700 mm to 5000×3500 mm
Power Consumption: 6 to 90 kVA

Standards and Compliance
The systems comply with standards such as ISTA-1A, 1B, 2A, 2B, MIL-STD-810, and others. They require a 3-phase AC380V±10% 50/60Hz power supply.

Conclusion
The KRD50 and KRD51 series provide comprehensive solutions for simulating transportation conditions, ensuring that products and packaging can withstand the rigors of transport.

MECHANICAL TESTING SOLUTIONS €CME Adopt truck chassis suspension tech nology, the acceleration factor can be adjusted; AC variable frequency control; KRD50TRANSPORTATION SIMULATIONTEST SYSTEM KRD50 series transportation simulation test system is to simulate the actual road conditions such as shocks and vibrations during the transportation of various items of a specific load, and to evaluate the effect of the actual working conditions on the loading, unloading, transportation, packaging, sealing or internal structure of the goods. In order to assess or confirm the products and packaging. The method of subband approach is used to simulate broadband random vibration. Each subband contains a main natural frequency and meets the power spectrum of the subband. The vibration magnitude and running time of the test bench are consistent with the actual road spectrum. TECHNICAL SPECIFICATIONS TECHNICAL SPECIFICATIONS Bounce testing simulates the constant loose cargo state during truck transport. Often times, containers carrying military and civilian hardware (such as: medical supplies, electronics, weaponry, communication devices) travel for extended periods of time and must be transported off-road. All of these items must maintain functionality upon arrival at their destinations. The International Safe Transit Association (ISTA) developed a civilian package test procedure resembling the military test: 1A for products weighing less than 150 lb (68 kg) and 1 B for over 150 lb (68 kg). Additional tests in subsequent procedures such as 1C, ID, 2A and further combine the loose cargo basic test with atmospheric conditioning and other factors. MIL-STD-810 and ISTA Procedures 1A and 1 B offer package test procedures for packages subjected to repeated vibration (bouncing Testing) for a distance of up to 150 miles (240 km), while unrestrained and repeatedly colliding with other cargo and the walls and floor of a four-sided compartment.
