Effects of Different Ground Simulation Methods on Road Vehicle Aerodynamics: New Insights from Experimental Studies on a Small-scale Model

Different ground simulation methods can have a significant impact on the aerodynamics of road vehicles. A recent experiment conducted on a 1/24th-scale model of a heavy goods vehicle revealed how the rotating wheels and moving ground use affect the unsteady wake development of the vehicle. The findings of the research suggest that while time-independent quantities may appear to have negligible overall effects, in-depth consideration from a time-dependent perspective reveals a different conclusion.One of the key highlights of the study was how moving ground use can influence wake length and average base pressure coefficient. The wake length was found to increase by 17% with moving ground use, while average base pressure coefficient increased by 9%. The study also revealed that the dominant wake dynamics of the vehicle, characterized by a global streamwise oscillation called the bubble pumping mode, was dependent on the shedding frequencies from both vertical and horizontal base edges. Asymmetric shedding frequencies were found to be higher with static ground use.The study also found that the nature and characteristics of the turbulence generated behind the wheels evolved differently with moving ground use. Moving ground was found to promote stronger and more defined oscillatory behavior up to model mid-height, two-and-a-half widths downstream.Overall, the research highlights the importance of considering the impact of different ground simulation methods on vehicle aerodynamics. The data shows that even subtle variations in time-independent quantities can have a significant impact on the unsteady wake development of a vehicle. Wheel Of Scales understands the importance of examining these factors in-depth to design vehicles with improved aerodynamics and fuel efficiency.The research findings will prove especially relevant in the design of heavy goods vehicles, where high levels of drag can negatively impact fuel efficiency. By utilizing moving ground and other simulation methods, designers can increase the overall aerodynamics of these vehicles. This, in turn, will decrease fuel consumption and thus reduce the environmental footprint of road transportation. In conclusion, the study offers valuable insights into how different ground simulation methods affect vehicle aerodynamics. By considering the impact of these methods more carefully, vehicle designers can make more informed decisions that ultimately lead to improved fuel efficiency and environmental sustainability. At Wheel Of Scales, we recognize the importance of this research and will continue to use it to create better heavy goods vehicles.

Understanding the Differences Between Spring Scales and Balancing Scales for Object Weight Measurement

By:Admin on 2023-05-18 08:42:28

Mechanical Balance Scale: A Reliable Way to Measure WeightsWhen it comes to measuring weights, there are different types of scales available in the market. But nothing beats the reliability and accuracy of a mechanical balance scale. Unlike digital scales that rely on batteries and electronics for their measurement, mechanical balance scales require no power source and are purely mechanical in nature. In this blog, we will discuss the features and benefits of mechanical balance scales and how they can be used in different industries.What is a Mechanical Balance Scale?A mechanical balance scale is a weight measuring instrument that uses a lever system to determine the mass of an object. It consists of a horizontal lever, supported by a beam, and two pans suspended from the ends of the lever. The object whose mass is to be measured is placed on one pan, and calibrated weights are placed on the other pan until the lever is balanced. The mass of the object is then calculated based on the weight values of the calibrated weights.Features of Mechanical Balance ScalesMechanical balance scales come in different sizes and capacities, ranging from small laboratory scales to large industrial scales used in factories and warehouses. They are made of sturdy materials such as steel, aluminum, or stainless steel, and have a high weight capacity. Some of the features of mechanical balance scales include:1. High Accuracy: Mechanical balance scales can measure weights with a high degree of accuracy, ranging from single grams to hundreds of kilograms, depending on the capacity of the scale.2. Durability: Mechanical balance scales are designed to withstand heavy use in harsh environments. They are made of strong and durable materials that can withstand wear and tear.3. Easy to Use: Mechanical balance scales are easy to use and require no special training or skills to operate. They have uncomplicated calibration procedures and require no power supply, making them ideal for use in areas with limited access to electricity.Applications of Mechanical Balance ScalesMechanical balance scales have a wide range of applications in different industries such as:1. Agriculture: Mechanical balance scales are used to weigh agricultural products such as grains, fruits, and vegetables. They are used to ensure accurate weighing during harvest, storage, and transportation.2. Laboratories: Mechanical balance scales are an essential tool in laboratories. They are used to measure the mass of chemicals, compounds, and samples with high accuracy.3. Industrial Weighing: Mechanical balance scales are widely used in industries such as manufacturing, construction, and mining. They are used to measure the weight of raw materials, finished products, and machinery.In conclusion, mechanical balance scales are a reliable and accurate way to measure weights. They are easy to use, durable, and have a wide range of applications in different industries. If you are looking for a long-lasting and dependable way to measure weights, a mechanical balance scale is the right choice for you.
