Product overview:
1 the engine suspension dynamic fatigue tester has features such as ease of use, high control accuracy and good reliability. The series of test machines was developed and developed using advanced electron-serving dynamic tester techniques and designed in conjunction with the actual use status of domestic users。
2. The electron server is capable of conducting both dynamic high and low weekly fatigue tests, process control fatigue tests, static constant rate, constant variability, constant stress controlled tests and routine mechanical performance tests, as well as cracking mechanics tests, partial vibration and shock tests as required, and fatigue life of materials or components in a broad range, crack extension, break-up resilience performance tests, safety evaluation of actual tests, and work simulations。
Characteristics of engine suspension dynamic fatigue test machines:
1. Product composition:
The 100kn liquid-serving fatigue test system consists mainly of a 100kn-serving line-lifter, a constant-serving pump station, a loaded dragon door framework (customer-equipped), a test kit, a full-digit 2-channel server (one channel reserved) and computer printers, associated test software, other necessary accessories, etc。
2. Actors:
2. 1. Design pre-resilience ring-linking of test traps to the servinating line enablers, load sensors and test traps to further enhance dynamic response performance。
2. 2 structural characteristics:
1) the system uses a lacuna device to remove institutional connections and trajectories, automatically fixes power values, reduces side forces, reduces the impact of high-frequency pressure tests and improves the test wave shape。
2) the use of multi-level soft support combination-led institutions with excess pressure of less than 0. 3 mpa and no creeping phenomenon。
3) a combination of seals, high pressure seals, low pressure seals and leaks, and a tank is always oil-free。
4) the sensor is placed inside the piston and is flexible in motion without external interference。
5) the combination seal structure is well interchangeable and easier to maintain。
6) pistols are simple and are supersophisticated, with surface polishing up to rα 0. 4u。
7) structural formation: two poles, two effects。
