MEMS Accelerometers
Discover cutting-edge solutions from 8 leading global suppliers
Industrial and test measurement MEMS DC accelerometers by Silicon Designs Inc (SDI) can be used to provide advanced vibration diagnostics and platform optimization.
From aerial drones, to ground robotics, or autonomous marine vehicles, managing vibration is critical to ensuring mission readiness, equipment longevity, and sensor accuracy. Excess vibration not only threatens structural integrity but also disrupts sensitive electronics, optics, and payloads.
Precision Vibration Monitoring for Autonomous Systems
Unmanned platforms are constantly exposed to dynamic operating conditions, from the rapid accelerations of UAV launches to the rough terrain traversed by UGVs. These forces can introduce harmful vibration patterns that degrade performance over time or mask early signs of component fatigue. Silicon Designs’ rugged MEMS DC accelerometers give engineers the ability to detect and isolate these issues during R&D, testing, and even in deployed operations.
By integrating SDI sensors across a vehicle’s frame, suspension, propulsion systems, and payload mounts, test teams can gather high-fidelity vibration data in real-time. This insight enables smarter design decisions, fine-tuned damping strategies, and early intervention before minor faults evolve into mission-critical failures.
Real-Time NVH and Structural Data Collection
Noise, Vibration, and Harshness (NVH) analysis is no longer just for manned vehicles. In unmanned systems, NVH metrics can directly influence flight stability, imaging quality, stealth performance, and system health. Engineers using Silicon Designs’ single-axis (2240, 2266) and triaxial (2466, 2480) accelerometers can simulate demanding operational environments, from turbulent flight paths to armored vehicle impacts, all while collecting real-time vibration signatures across multiple test points.
These sensors offer DC response capabilities ideal for capturing low-frequency movements and subtle shifts in structural loading, signals that traditional piezoelectric accelerometers often miss. With this level of detail, developers can pinpoint where structural reinforcements, isolation materials, or system redesigns are needed.
Reducing Failure Risk with Predictive Vibration Diagnostics
As unmanned platforms become more autonomous and are expected to operate for longer durations without human intervention, early detection of wear and imbalance becomes critical. Silicon Designs’ MEMS accelerometers enable predictive diagnostics in key systems like electric motor mounts, suspension linkages, and propeller drives. By monitoring vibration trends over time, engineers can schedule maintenance before a failure occurs, reducing the risk of unplanned downtime or in-field malfunctions.
This approach not only extends the lifecycle of unmanned vehicles but also supports data-driven maintenance cycles, particularly important for large fleets of UAVs or autonomous ground systems operating in remote or tactical environments.
