Linkotest Bump Test Machine
Linkotest offers PC-controlled pneumatic shock testers known as Bump Test Machines. These machines are designed to ensure accurate and repeatable shock testing for both laboratory and production environments. They are capable of testing samples weighing up to 1000 kg (depending on the model).
Equipped with shock pulse programmers, these machines can generate short and long duration half sine shock pulses. This functionality allows them to meet strict automotive, military, and industrial specifications, as well as customized testing requirements. The generated waveforms comply with various military standards, such as MIL-STD-202, MIL-STD-750, MIL-STD-810, and MIL-STD-883.
The primary purpose of the bump test machine is to replicate the effects of repeated bumps that components and equipment may experience during transportation or when installed in different vehicles. These machines are mounted on an air spring and utilize heavy shock absorbers, effectively isolating them from the ground. This design ensures accurate simulation of real-world bump conditions while maintaining stability and reliability during testing.

Bump Test Machine Supplier FAQ
Bump Test Machine FAQ Guide
If you want to learn about the bump test machine, then our guide is for you. It covers everything you need to know about the bump test machine in terms of definitions, applications, benefits, and more. You’ll learn everything you need to know in this guide – let’s get started:
A bump test machine is an automatic pneumatic lifting vertical impact testing system. It is a kind of vertical impact test equipment with a novel design, a high degree of automation, simple operation, and convenient maintenance. You can use it to measure and determine the impact resistance of products or packaging in impact environments. In addition, the functional reliability and structural integrity of the product under impact can be assessed. Our pneumatic shock test system can perform a variety of conventional classical impact tests. Realize the shock wave and shock energy of your product in the real environment to improve your system or optimize the structure of your product.
Linkotest designs and manufactures shock test systems including mechanical shock test machines, bump test machines, incline impact tester, and other products to meet your different impact testing needs.
- Windows-based stability control system: automatic remote control interface, you only need to enter a simple value, and the impact control measuring instrument can accurately complete the impact test.
- Full pneumatic drive shock, clean and environmentally friendly, simple structure, and high reliability.
- Pneumatic drive greatly improves the shock test efficiency, maximum shock rate of up to 120 times/min.
- You can control the impact rate by adjusting the gas pressure, and the shock rate can be adjusted continuously.
- High-performance cast aluminum table: cast aluminum table has high strength and hardness, as well as a higher first-order resonance frequency, low noise, and no clutter;
- Complete measurement system: The system stores a variety of waveform tolerance zones, which is convenient for you to adjust and apply, and automatically completes the test report generation after the test is completed.
- Convenient installation: The equipment comes with a high-performance shock absorber and isolation device. You do not need a special foundation, easy to install, safe, and reliable.
This equipment is mainly used for life testing of auto parts.
In general, a bump test machine can be used to test weights from 50 kg to 2000 kg. Accelerations ranged from 3 “g” to 3000 “g” for subjects with pulse durations ranging from 3 milliseconds to 20 milliseconds. In addition, the machine is designed to reproduce components and equipment. This equipment may experience the effects of repeated bumps of 60 to 180 degrees per minute when transported or installed in various vehicles. And the machine is mounted on an air spring that uses heavy-duty shock absorbers to isolate it from the ground.
The pneumatic vertical shock test system is composed of three parts: a table body, a pneumatic control system, and an electrical control measurement system.
There are two types of bump test machines.
1）Free fall type
This machine is suitable for test object weight of 50~2000kg, acceleration of 3~60g, and a pulse time of 3~20ms test. In fact, the machine is designed to reproduce the effects of repeated collisions. Between 60 and 180 of these collisions per minute can be caused by various types of vehicle transport or installed parts and equipment. The machine is mounted on an air spring, and heavy shock absorption is also used to isolate it from the ground.
As we all know, the bump tester is a general-purpose testing device that performs impact tests according to various national and international standards such as IS, MIL, EN, ISO, IEC, DEF, and ASTM.
2）Force fall typ
Our custom strong steel construction enables it to be used for testing objects weighing from 50kg to 2000kg. Acceleration is from 3 “g” to 200 “g”, and pulse duration is from 3ms to 30ms. The object mounting hole format of the platform is a 100 x 100mm matrix according to customer requirements. Select T-slot mounting test objects can also be used.
The mounting platform is raised vertically by the CAM device and allows it to land freely/forcefully on an elastomer pad (semi-sinusoidal programming pad) placed on the anvil. The required level of acceleration is provided by such means.
You can obtain the desired impact acceleration by adjusting the drop of the mounting platform. In addition, the use of the elastic gasket produces a half-sinusoidal pulse, the duration of which can be adjusted by changing the hardness and thickness of the rubber gasket.
Generally speaking, the pneumatic impact test system is equipped with a half-sine wave generator. The half-sine wave generator is mainly made of engineering rubber (considering the stiffness and cohesion of rubber) and felt pads of various thicknesses.
Different thicknesses are connected in series to form multiple rigidities, giving you different shock pulse widths. The post-peak sawtooth generator is a lead cone. The trapezoidal wave generator gas source is high-pressure nitrogen, the pressure range is 1-10MPa. The overload value can be adjusted between 10-100g.
