Vibration Shaker Climatic Chamber Meeting MIL STD-202g Method 201A Requirements

1. Product Name and Purpose

2. Product Features

• Robust and Insulated Chamber Construction
  • The climatic chamber is built with a heavy-duty steel frame that provides exceptional rigidity and stability. The frame is coated with a corrosion-resistant finish to enhance its durability in harsh testing environments. The chamber walls are made of high-quality insulation materials, which minimize heat transfer and maintain precise temperature and humidity levels. The insulation is engineered to withstand the rigors of continuous testing and prevent any external factors from interfering with the internal test environment. The chamber is also equipped with a hermetic door seal, ensuring a leak-free enclosure and consistent test conditions.
• Precision Temperature and Humidity Control System
  • The chamber features a highly accurate temperature and humidity control system. It can maintain a wide temperature range, from -60°C to +180°C, with an accuracy of ±0.5°C. The humidity control range extends from 10% to 98% relative humidity, with an accuracy of ±2% RH. The system utilizes advanced refrigeration units, electric heaters, humidifiers, and dehumidifiers to achieve and maintain the desired environmental conditions. The temperature and humidity sensors are strategically placed within the chamber to provide real-time feedback, enabling the control system to make rapid and precise adjustments.
• Powerful Vibration Shaker
  • Integrated into the chamber is a high-performance vibration shaker. It is capable of generating a wide range of vibration frequencies and amplitudes. The frequency range can span from 2 Hz to 2000 Hz, allowing for the simulation of various real-world vibration sources, such as machinery operation, transportation, and seismic activity. The vibration amplitude can be adjusted from a few micrometers to several centimeters, depending on the test requirements. The shaker is mounted on a vibration isolation platform to prevent any external vibrations from affecting the test results and to ensure the safety of the surrounding laboratory environment.
• Synchronized Control and Data Acquisition
  • The system features a sophisticated control panel that allows for seamless synchronization of vibration and climatic parameters. Operators can precisely program the sequence and intensity of vibrations, temperature changes, and humidity levels, creating custom test profiles that meet MIL STD-202g Method 201A requirements. The control panel also provides real-time monitoring of all test parameters, including temperature, humidity, vibration frequency, amplitude, and sample status. The data acquisition system records detailed information about the test, such as temperature and humidity profiles, vibration waveforms, and any changes in the physical properties of the sample. The acquired data can be stored in a variety of formats and analyzed using specialized software to generate comprehensive test reports.
• Compliance with MIL STD-202g Method 201A
  • The equipment is specifically calibrated and programmed to perform tests in strict accordance with MIL STD-202g Method 201A. It can replicate the specific temperature and humidity cycling, vibration profiles, and test durations specified in the standard. This ensures that the test results are valid and comparable, allowing manufacturers to make informed decisions about product design, material selection, and quality control. The chamber also provides a means for documenting compliance with the standard, which is essential for product acceptance in military and defense applications.

3. Specific Parameters

• Maximum Temperature Swing Rate
  • The chamber can achieve a maximum temperature swing rate of 5°C per minute. This rapid temperature change capability is essential for simulating sudden environmental temperature fluctuations, such as those experienced during rapid altitude changes in aerospace applications or during the startup and shutdown of military equipment. For example, in testing electronic components for a missile guidance system, the ability to quickly change the temperature helps evaluate their performance under extreme and dynamic thermal conditions.
• Humidity Change Rate
  • The humidity change rate can be adjusted up to 10% RH per minute. This allows for the simulation of rapid humidity transitions, such as those that occur when moving from a dry indoor environment to a humid outdoor environment or vice versa. In military electronics, this is crucial for testing the moisture resistance of circuit boards and components, as high humidity can cause condensation and lead to short circuits or corrosion.
• Maximum Vibration Acceleration
  • The vibration shaker can produce a maximum vibration acceleration of up to 100 m/s². This high acceleration level is sufficient to replicate the intense vibrations experienced in heavy military machinery, high-speed transportation, and seismic events. For instance, in testing the durability of a military vehicle's suspension components, a significant vibration acceleration can help assess their durability and resistance to fatigue under extreme mechanical stress.
• Testing Volume and Payload Capacity
  • The chamber offers a customizable testing volume, with options ranging from 1 m³ to 20 m³. The payload capacity can be adjusted according to the size and weight of the test samples, with a maximum capacity of up to 2000 kg. This flexibility allows for the testing of a wide variety of products, from small electronic devices to large military equipment assemblies.
• Vibration Shaker Displacement Range
  • The vibration shaker has a displacement range of ±75 mm. This range enables the simulation of both small, high-frequency vibrations and large, low-frequency oscillations. It is particularly useful for testing the performance of products with different resonant frequencies, such as mechanical springs, shock absorbers, and vibrating screens.

4. Product Functions

• Accurate Simulation of Military Environmental and Mechanical Conditions
  • The primary function of the apparatus is to provide a precise and reliable simulation of the combined temperature, humidity, and vibration conditions specified in MIL STD-202g Method 201A. By accurately replicating these conditions, it allows military contractors and manufacturers to evaluate the performance and durability of products and materials. For example, in the aerospace and defense industry, it can be used to test the integrity of satellite components, avionics systems, and weaponry under the combined effects of extreme temperatures, high humidity in certain environments, and the vibrations caused by rocket launches, aircraft flights, and military operations.
• Product Design Optimization and Quality Control
  • Through a series of tests on different product prototypes, the data obtained from the system can be used to optimize designs. Manufacturers can analyze the behavior of various materials and components under the specified environmental and mechanical stresses. For instance, a military electronics manufacturer can study the effect of temperature and humidity on the performance of a new radar system design and make adjustments to improve its reliability. The apparatus also serves as a vital tool for quality control, ensuring that each batch of products meets the required standards and specifications.
• Research and Development Support
  • In the field of military research and development, the combined chamber and shaker offer valuable insights. Researchers can use it to study the fundamental properties of materials and the interactions between different environmental and mechanical factors. They can explore new materials and technologies that are more resistant to temperature, humidity, and vibration. For example, a materials science research team may use the equipment to test the performance of a new composite material and analyze its potential applications in military equipment, such as body armor or aircraft structures.
• Compliance Testing and Certification
  • The equipment is essential for conducting compliance testing to meet MIL STD-202g Method 201A and other relevant military and industry standards. Many military and defense applications require products to pass specific environmental and mechanical tests to ensure their quality and safety.
